EN 15567-1 : 2007 ; Sports and recreational facilities -Ropes courses – Part 1: Construction and safety requirements

Introduction

Ropes courses vary considerably and may be used for education, recreational, training or therapeutic purposes.

Ropes course activities involve risks that should be managed by the operators. This is achieved through careful supervision, training, instruction, information etc.
Ropes course activities should only be taken by those who are physically and mentally able to comply with the safety requirements specified by the operator.

The various safety devices (for protection against falling from a height and collisions) consist of equipment designed to limit the consequences of falls or collisions. There are inherent risks associated with ropes courses. These risks should, however, be appropriately managed and minimized by the ropes course operator and his staff; it should be understood that they can not be eliminated altogether.

On the basis of a risk assessment, operators should take reasonably practicable measures to ensure the safety of participants. This means that the degree of risks in a particular job/work place/facility need to be balanced against the time, trouble, cost, benefits and physical difficulty of taking measures to avoid or reduce the risk.
Ropes course operators should also consider EN 15567-2, when carrying out risk assessments.

Safety in use

Sport surfaces undergo a complex reaction when subjected to loading. The desired components of the interaction are deformation under load, the ability to absorb impact, and the energy restitution of the impact, i.e. the amount of energy returned to sports person from the surface on which he/she is performing.

The ability of surface to absorb an impact is an important safety feature of sports surface, Values specified are, therefore, inevitably a compromise between these fundamental characteristics, sports surfaces react differently under different temperatures and strain rates: they become harder at low temperatures and softer at high temperatures.

An important requirement for safety and sports performance is for there to be sufficient grip between the footwear of athlete and the sports surface. Insufficient grip can result in the athlete slipping on the surface: to much grip can place un acceptable stress on joints and muscle ligaments.

CISCA 절차 단원 5 축하중 시험

Section 5
Pedestal Axial Load Test

Purpose:

To verify the axial load an access floor pedestal assembly can withstand without structural failure or damage to components inclusive of threads, nuts, collars, etc.

Preparation:

1.A minimum of three (3) randomly selected pedestal assemblies shall be tested for each floor height. Pedestals shall be identical to those used in normal installations for their corresponding floor heights, including thread engagements normally utilized in field conditions.
2.Pedestal assemblies shall be tested for maximum floor heights of each assembly design or configuration.
3.Loads shall be imposed and measured through a properly calibrated and appropriately sized load sensor over the center of the pedestal head. The load indentor or applicator may be machined to integrate with the pedestal head to simulate the loading of the four corners of the panels.

Test Procedure:

1.Align the Pedestal assembly in the testing apparatus and apply an increasing load centered on the pedestal until the desired load is reached. Hold imposed load for minimum of one (1) minute duration. The load shall then be relaxed and the assembly visually inspected for damage. Adjusting devices, locking devices, threads shall be workable by hand. Rate of load application shall not exceed 10,000 pounds per minute (44.5 kN/min).

 

Report:

1.Reference of testing procedure described herein by CISCA A/F section number shall be included in report.
2.All apparatus, equipment, instrumentation, accuracy ranges, etc. shall be described including equipment calibration/certification dates.
3.Materials tested shall be fully described or referenced to manufacturers’ drawings and part numbers containing the following:
- Materials of construction, weight, nominal dimensions and thicknesses.

4. Report load applied and relaxed for each pedestal and describe damage to components, if any.

Section 10
Air Leakage Test
(Through Panel Seams)

Purpose:

To determine the rate at which air will pass through the cracks and gaps in an access floor panel assembly, at
a specified and controlled differential static air pressure. This test applies only to floors used for underfloor air distribution.

Preparation:

1.The test shall be performed on a specimen of panels in a relatively airtight box or chamber, as shown below. The gap between the perimeter of the floor panels and the chamber opening shall be sealed to minimize air leakage.
2.The dimensions of the panel assembly shall be at least 72 inches (1829 mm) square. Finished floor height shall be 12 inches (305 mm), or the maximum height of the system; whichever is less.
3.Any coatings, stringers, gaskets, pads, clips, fasteners, or other materials normally used shall be
identical to that utilized in an installed system. The pedestals shall be anchored to the base of the chamber only if such anchorage will affect the air leakage rate in some way. If so, such anchorage
shall be described in the report.
4.A controllable blower, fan, or air pump shall be fitted to the chamber to supply airflow to the chamber at
a rate sufficient to maintain the positive air pressure required. The system should provide essentially constant airflow for a period of time sufficient to obtain readings of airflow rate and pressure.
5.A flowmeter or other suitable device to measure the rate of airflow into the test chamber shall be fitted.
A manometer or other suitable device to measure the differential test pressures shall be connected between the chamber and atmosphere.
Note: The referenced test method, ASTM E283, requires the device be capable of recording the pressure within ±2% of set point. The static air pressure differentials typically employed in under floor air
distribution systems are much lower than in the referenced method, so care must be taken by the test agency to employ the appropriate pressure measuring device.

Test Procedure:

1.Calibrate the air leakage test equipment in accordance with the calibration instructions in ASTM E283 Standard Test Method For Determining Rate of Air Leakage Through Exterior Windows, Curtain Walls, and Doors Under Specified Pressure Differences Across the Specimen , except that the calibration pressure shall be 0.10 inch of water column (25 Pa).
2.With the floor specimen installed as described above, adjust the total airflow into the chamber to provide the specified test pressure difference across the test specimen. When the test conditions have stabilized, record the airflow through the flowmeter, and the test pressure difference. This measured air flow is designated the total air flow, Qt(p)n, where p is the pressure, and n is the number of the measurement. Measure the barometric pressure, B, and temperature of the air at the test specimen, T.
3.Repeat the measurement of the leakage at each pressure level at least 4 times. Calculate the arithmetic average of all leakage measurements at each pressure, Qt(p).
4.Seal all gaps and holes in the floor specimen.
5.With the floor specimen sealed, measure the amount of air leakage through the test chamber itself, at the same air pressure differentials as in step 2. Each measured air flow is designated the extraneous airflow, Qe(p)n.
6.Repeat the measurement of the extraneous leakage at each pressure the same number of times as in step 3. Calculate the arithmetic average of all extraneous leakage measurements at each pressure, Qe(p).
7.Measure the total crack length between the access floor panels, l. Do not include any of the joints between the perimeter of the specimen and the chamber.

The Calculation:

1.Calculate ratio Ap/lp , where:
Ap = Area of a floor panel, ft² (m²)

lp = Perimeter of a single floor panel, ft² (m²)

Note: For some systems, where multiple panel sizes or shapes are employed together in one floor assembly, determination of lp may require more careful analysis. Generally, the perimeter of each panel should be measured only once in determining lp.

1.Express the total average air flow at each pressure Qt(p), and the extraneous average air flow at each pressure Qe(p), in terms of flow at standard conditions, as outlined in ASTM E283.
Note: Ensure all units of measure referenced in the E283 calculation are observed, and that the correct equation is employed.

1.Express the air leakage through the test specimen at each pressure, Qs(p), as
Qs(p) = Qt(p) – Qe(p), ft³/min (L/s) (1)

1.Calculate the rate of air leakage per unit crack length at each pressure, ql(p), as
ql(p) = Qs(p)/l, ft³/min-ft (L/s-m) (2)

1.Calculate the rate of air leakage per unit area at each pressure, qA(p), as
qA(p) = ql(p) / [2 (Ap/lp)], ft³/min-ft² (L/s-m²) (3)

Report:

1.Reference of testing procedure described herein by CISCA A/F section number shall be included in the report.
2.All apparatus, equipment, instrumentation, accuracy ranges, etc., shall be described including equipment calibration/certification dates.
3.Materials tested, and specimen configuration(s) should be fully described in text and/or photograph and/or drawing, or by reference to manufacturer’s drawings and/or part numbers, including the following:
Panels:

. Floor finishes

. Materials of panel construction

. Weight, nominal dimensions and thicknesses

Supporting structure:

. Height

. Materials, sections, fasteners, adhesives or other anchors

Other:

. Fully describe other materials used in the mock-up

4. For each of test pressures, report the rate of air leakage per unit crack length, and per unit area, as noted. At a minimum, report the air leakage rate at the pressures noted in the table. Other pressures may also be reported, at the discretion of the proponent or authority. Calculated accuracy of the measured air leakage, based on the precision of the air pressure measurement.

CISCA Glossary of Terms

Access Floor System

An access floor system is an elevated or “raised” floor area upon another floor (typically a concrete slab in a building) creating an interstitial space for service distribution. It consists of modular floor panels that are designed to be removable from their support so that “access” to services is quickly and easily achieved. These services may include but are not limited to electric power, data, plumbing, telecom, environmental control, air conditioning, fire detection suppression, security, etc.

Air Leakage

As it pertains at access floors, air leakage is defined as the passage of air from an underfloor air cavity through elements other than the designed air outlet devices. Leakage typically falls into two categories: 1) leakage in the air cavity under the floor due to construction quality, and 2) leakage through floor panel seams and other non-air outlet devices.

Axial Load

A vertical load (or force) whose line of action passes through the center of the member’s cross sectional area and is perpendicular to the plane of the section such that no bending or torsion moments are produced. This is the load that is typically specified when referring to the axial load performance of an access floor pedestal support.

Beam Deformation

Deformation is defined as the act of distorting or changing the shape or dimensions of a structural element or body resulting from forces or stresses. Beam deformation as related to access floors is generally the term used when referring to the permanent set of the entire span of the access floor panel after application of a rolling load and is determined by measuring the overall flatness of the access floor panel before and after the application of the load.

Concentrated Load

A single load or force that has a small contact area as to be negligible compared with the entire surface area of the supporting member. Concentrated loads (sometimes referred to as static loads) are typically imposed by stationary furniture and equipment with legs. A concentrated load is applied to the surface of the panel (1″x 1″ square or 1.128″ diameter indentor) (25.4 mm x 25.4 mm square or 28.65 mm diameter) resulting in deflection and permanent set. Concentrated load rating is specified in pounds force applied over a one square inch (645 mm2) area.

Deflection

Deflection is the vertical displacement of a structural member or system under load. This is generally referred to when discussing the vertical displacement a floor panel experiences upon application of a concentrated load or uniform load.

Design Load

The load expected to be imposed on the floor system in service. The access floor concentrated load rating is not the safe working load or design load for the floor system.

Dynamic Load

Loads that vary significantly with time as measurements are being made. Two dynamic loads are generally referred to: rolling loads and impact loads.

Finished Floor Height

Finished floor height is defined as the height of the access floor system as measured from the top of the supporting sub-floor to the top of the access floor panel.

Impact Load

Impact loads are caused by objects being accidentally dropped onto an access floor. These loads are defined by the weight of the load, height, or distance dropped, impact area, and hardness/softness of the object. Impact loads generate severe shocks that can cause structural and panel damage. Impact loads most often occur during construction, move-in, and equipment/furniture rearrangements.

Live Load

A live load is produced by the use or occupancy of the building. This does not include construction, environmental, seismic, or access floor dead loads. The live load should not be confused with the uniform load capacity of an access floor.

Local Deformation

Local deformation is generally the term used when referring to the permanent set recorded along the wheel path after a rolling load test. It is determined by measuring the local flatness of the panel along the wheel path before and after the application of the load using a 6″ (152 mm) spanner perpendicular to the wheel path. The difference between before and after measurements is defined as local deformation.

Overturning Moment

Overturning moment is the term generally used to refer to the capacity of the floor pedestal attached to a supporting floor to withstand tip over forces generated by the application of a lateral force applied to the top of a moment arm. Overturning moment capacity is calculated by multiplying the lateral force by the height at which the force is applied.

Panel/Panel Assembly

Modular and removable structural floor element or elements designed to rest on separate or integral elevated supports that may be used as an interstitial space for distribution of building services (wire, cable, air, etc.).

Pedestal (Adjustable Height)

An access floor pedestal with adjustable height option is defined as the structural element that supports the access floor panel and raises it off the floor slab to create an interstitial space for service distribution. The adjustable height or leveling feature of the pedestal allows the access floor panels to be installed level regardless the changes in elevation of the floor slab.

Pedestal (Fixed Height)

A fixed height floor pedestal is defined as the structural element that supports the access floor panel and raises it off the slab to create an interstitial space for service distribution. The fixed height floor pedestals and corresponding access floor panels are designed to lay on the floor slab and follow its contour and undulations.

Permanent Set

A material that is deflected so far that its elastic properties have been exceeded and it does not return to its original condition upon release of load is said to have taken a “permanent set.”

Raised Floor System (See Access Floor System)

Rolling Load

Rolling loads are dynamic loads typically imposed by equipment on wheels moving across the access floor.

Stanchion

The term stanchion is sometimes used to describe an access floor pedestal.

Static Load

Static load is defined as a force that does not undergo a change in magnitude or direction during a measurement procedure. Three static loads are generally referred to: concentrated, ultimate and uniform loads.

Stringer

A stringer is a structural element used to connect access floor pedestals together, thus providing lateral stability to the system and floor supports.

Uniform Load

Uniform load is a static force applied equally over the entire area of an access panel and is typically imposed by stationary furniture, equipment without legs, boxes, pallets, etc. The uniform load rating is specified in pounds per square foot or Newtons per square meter.

Ultimate Load

The greatest applied vertical static force(s) beyond which additional deflection is achieved without additional load or resistance.

ISO 8124-4, ISO 8124-3 Address Toy Safety, Dangerous Materials

국제 표준화기구 (ISO)는 안전하지 않은 장비 및 장난감에있을 수있는 위험 물질로부터 어린이들에게 부상의 위험을 줄이기위한 두가지의 장난감 안전 기준을 발표했다.
표준 :

ISO 8124-4:2010 – 장난감의 안전성 – 제 4 부 : 그네, 슬라이드와 실내 및 실외 가족 가정용 유사한 활동 장난감
ISO 8124-3:2010 – 장난감의 안전성 – 제 3 부 : 특정 요소의 마이그레이션 .

의도적 재생 (일반 사용)뿐만 아니라 의도하지 않은 재생  (합리적으로 예측 남용)의 사용에서 발생하는 잠재적 인 위험을 최소화 할 수 있도록 설계되어 있습니다.
ISO 8124-4:2010 그네, 슬라이드 및 14 세 미만의 어린이들이 실내 및 야외에서 사용되는 다른 활동 장난감과 “가족 상황”만에 요구 사항 및 시험 방법을 제공합니다.

함께 위험 분석과 사고 데이터는 ISO 8124-3의 새 버전의 개선을위한 기초이었다, ISO는 말했다. 개정 된 기준은 장난감을 섭취하는 경우 해의 위험을 줄여 잠재적으로 독성 요소에 아이들의 노출을 최소화 할 계획이다.

ISO 8124-3:2010은 아마도 장난감에서 발견 된 비소, 카드뮴, 납, 수은 및 다른 재료와 같은 위험 물질의 최대 허용 수준을 제공합니다. ISO 8124-3:2010는 이전의 1997 판을 대체합니다.

장난감 안전, ISO 기술위원회 ISO / TC 181 단단하기위한 지속적인 노력의 일환으로, 장난감의 안전도 (각각 2009 년과 2007 년) ISO의 장난감 안전 시리즈의 첫 번째 두 부분을 업데이트하고 개선 :

제 1 부 : 기계적 및 물리적 특성과 관련된 안전 측면
2 부 : 가연성
ISO 8124 시리즈는 세 부분으로 첨가하여 가까운 미래에 확장 할 것으로 예상된다. 이들은 다음을 포함한다 :
