연소특성시험
ASTM E 84 – Surface Burning Characteristics-Fire safety technology
표면연소 특성이란?

재료의 표면연소 특성은 연기생성을 제한하고 동시에 화염에 저항하는 능력을 종합적으로 평가하는 것으로써 보통 건축법이나 기타 정부등의 기관에서 규정한다.

내부 벽이나 천장 마감 재료로 사용되는 재료에 있어서 화염 전파율은 중요한 물리적 특성 중에 하나이다.

통제된 화재 조건에서 상대적으로 표면 연소 특성을 결정하기위한 표준적인 시험방법은 수평 화재 터널 장치(Steiner Tunnel)를 이용하는 ASTM E 84이다. 이 방법은 비록 두 측정이 직접적 연관이 적을 수 있지만, 화염의 확산 및 연기의 확산 지수를 결정하고, 특정설치요구사항에 대한 재료의 적용성을 결정하는데 도움이된다.

 

시험 방법

ASTM E 84 ; 건축 자재의 표면연소 특성에 대한 시험표준 방법에 지정된 스타이너 터널은 특정한 시험 조건하에서 물질의 상대적 표면연소 특성을 결정하기 위해서 설계되었습니다. 시험의 결과는 화염확산 지수( FSI )와 연기발생(SD) 지수로 표현됩니다.

이 스타이너 터널은 규정된 특정한 온도로 예비 가열하고 또 사전시험온도로 냉각이 허용되며 12인치 폭과 24피트 길이의 터널뚜껑을 열고 시료를 설치할 수 있도록 되어 있다. 터널 천정에 설치되는 시험편은 장치의바닥을 향해 설치된다. 뚜껑이 덮여지고 버너를 점화하여 시편의 한쪽에서 불꽃을 인가한다. 화염확산 거리를 관찰하고 10분 이상동안 매초마다 확산거리를 기록하고 레드 오크(임의로 할당된 100에 대한 FSI 및 SD )의 비교치에 근거한 FSI 및 SD 를 결정하기 위하여 계산이 이루어진다 .

 

테스트 결과

ASTM E 84에는 등급기준이 포함되어 있지 않습니다. 그러나, 많은 업계 문서는 ASTM E 84 테스트 데이터를 참조 하고 일반적 등급기준을 적용합니다. 비록 각 문서에서 사용되는 용어가 서로 다를 수 있지만 등급범위는 일반적으로 동일하다.

 

일반적인 범위 :

클래스 A 또는 클래스 1 ( FSI = 0-25 )
클래스 B 또는 클래스 2 ( FSI = 26-75 )
클래스 C 또는 클래스 3 ( FSI = 76-200 )
위 모든 각 분류는 최대 450의 연기발생(SD )율을 규정함

테스트 실시 시기

ASTM E 84는 제품 개발 단계나 지속적인 기업 품질 보증 프로그램의 일부로 이용 될 수있다. 특히 북미와 중동의 많은 글로벌 관할권역의 건물관리는 내부 벽 및 천정 마감 재료에 대해 ASTM E 84를 강제하고 있고 나아가 지역별 기관의 강제요건에 따라 이들 재료에 대한 일회시험 반복시험, 확장시험(예 :30 분), 또는 더 집중적인 제품 인증 프로그램의 시험항목을 적용한 시험의 결과가 적용되어질 수 있다 .

 

시료 요구 사항

각 시험에서는 폭 21인치(533mm), 길이24피트(7,315mm)의 시료가 요구된다 (예:각 21인치 폭(533mm), 8 피트 길이(2,438mm)의 시료 3개가 필요). 시료의 두께가 3 인치(75mm) 미만 또는 6 인치 (150mm )보다 두꺼운 경우, 터널 뚜껑을 수정해야 표준시험을 할 수 있으며 유리 섬유 강화 시멘트 보드 또는 석고 보드가 일반적인 기판으로 사용되어 질 수 있다. 그 외 세부 내용은 시험소의 설비의 조건을 고려하여야 한다.

 

TEST PROCEDURE

ASTM E 84-13a
-”Standard Method of Test for Surface Burning Characteristics of Building Materials”

ASTM E 84-13a “건축 자재의 표면 연소 특성에 대한 표준 시험 방법”으로 지정된이 방법은 특정 시험 조건 하에서 재료의 상대적인 표면 연소 특성을 결정하도록 작성되었습니다. 시험의 결과는 화염 확산 지수 (FSI) 및 연기 발생 (SD)으로 표현되며  화염 데이터의 비교 표면 확산을 개발하기 위해 건축에 사용되는 재료, 제품 및 조립품에 이 시험방법이 적용 가능하지만, 시험 결과는 모든 건축 화재 조건에서 시험 된 물질의 상대적인 표면 연소 특성을 반영하지 않을 수 있습니다. 따라서 시험대상 및 시험목적 등을 고려한 시험조건을 검토하여야 합니다.

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
