EN 13238:建筑產(chǎn)品防火測試-基材選擇的調(diào)理方法和通則

EN 13238:Reaction to Fire Tests for Building Products - Conditioning Procedures and

General Rules for Selection of Substrates

Abstract摘要

The Construction Products Directive requires products to be tested in their end use condition which, for the purpose of substrates, could lead to an economically unrealistic large variety of tests to be carried out. This large spectrum has been reduced to a practical number of standard substrates that enables the majority of end use conditions to be represented. Rules for the selection of such substrates are also given in this standard. BS EN 13238 is for use in conjunction with European Standards covering the reaction to fire test methods for the relevant construction products.

BS EN 13238 describes the conditioning procedures for test specimens which will be tested according to the European standards for reaction to fire.

BS EN 13238 also covers the rules for the selection of substrates for construction products when carrying out reaction to fire tests.

BS EN 13238 does not contain requirements for:

? The pre-drying of test specimens for the non-combustibility test according EN ISO

1182

? Methods of cleaning (e.g. washing) and other methods for the assessment of

durability aspects, which are dealt with in the relevant product standards.

EN 13501-1:建筑產(chǎn)品和構(gòu)件的防火等級

EN 13501-1:Fire classification of construction products and building elements

Abstract摘要

This European Standard provides the reaction to fire classification procedure for all construction products, including products incorporated within building elements.

Products are considered in relation to their end use application.

This document applies to three categories, which are treated separately in this European Standard:

-construction products, excluding floorings and linear pipe thermal insulation products; floorings, linear pipe thermal insulation products.

EN 13823:建筑產(chǎn)品的對火測試反應(yīng)- 單體測試

EN 13823:Reaction to Fire Tests for Building Products - Bulding Products Excluding

Floorings Exposed to the Thermal Attack by a Single Burning Item

Abstract摘要

The Single Burning Item test can be considered as the backbone of the Euroclass system for building products. The test results are required for a classification D - B (combined with test results from EN 11925-2), for a classification A2 (combined with test results from EN ISO 1716), and sometimes for a classification A1.

TEST PRINCIPLE

The specimen is exposed to a diffusive flame of 30 kW. Combustion gases are collected by an exhaust hood for analysis. This gas analysis makes it possible by oxygen depletion to calculate heat release rate from the specimen. Smoke production is assessed by

measuring attenuation of a light beam by smoke in the exhaust duct. The burning behaviour of the specimen is observed for flame spread, and the occurrence of burning particles and droplets.

EN 50266-2-4:Common Test Methods for Cables under Fire Conditions - Test for Vertical

Flame Spread of Vertically-Mounted Bunched Wires or Cables Part 2-4:

Procedures - Category C

Abstract摘要

EN 50266 specifies methods of test for the assessment of vertical flame spread of

vertically-mounted bunched wires or cables, electrical or optical, under defined conditions.

The test is intended for type approval testing. The requirements for the selection of cables for testing are given in annex A. The flame spread is measured as the extent of damage of the cable sample. This procedure may be used to demonstrate the cable’s ability to limit flame spread.

This Part 2-4 covers Category C and relates to cables installed on the test ladder to achieve a nominal total volume of non-metallic material of 1,5 litres per metre of test sample. The flame application time is 20 min. The method of mounting uses the front of the standard ladder. The category is intended for general use where low volumes of non-metallic material are required to be evaluated.

A recommended performance requirement is given in annex B.

EN 50268:在燃燒條件下電纜通用測試方法-在規(guī)定條件下電纜燃燒煙密度測量

EN 50268:Common Test Methods for Cables under Fire Conditions - Measurement of

Smoke Density of Cables Burning under Defined Conditions

Abstract摘要

The test is performed inside a chamber measuring 3 metres by 3 metres by 3 metres and the test is sometimes referred to as the three metre cube test.

The number of lengths and the mounting arrangement of the cables is dependant upon its outer diameter. Once the specimens have been bundled as required, they are placed onto the specimen stand and an alcohol fuel source is placed below the test specimen. At the start of the test the fuel is ignited.

The test is performed by monitoring the transmittance reduction of a white light beam, running from one side of the chamber to the other at a set height, thus monitoring the build up of smoke inside the chamber. A small fan is utilised inside the chamber to

prevent the smoke building up in a layered effect and a draft screen is utilised to protect the specimen and the flame source from any wind turbulence.

The test duration is 40 minutes.

Test Results

The minimum percentage light transmission is often used to determine if the product has passed or failed the test, often a minimum light transmittance of ≥ 60% is applied in order to classify a cable as low smoke (though this does depend upon the specification document).

Sometimes the limits supplied in specification documents are Ao values. The Ao results are generally calculated by use of the following equation (in accordance with the Beer- Lambert law), converting the transmittance of light received by the detector into the measured optical density of the smoke (Am):

Am = log10 (I0/It)

Where:

I0 is the initial luminous intensity

It is the transmitted luminous intensity

Ao is calculated by the following equation:

Ao = (Am x V) / (K x l)

Am is the optical density measured in the cube.

V is the volume of the cube in metres.

l is the length of the optical path between the windows in metres.

K is the number of units of material constituting a test specimen.

NB. The value of K is the number of lengths of cable used in the test specimen.

EN 60695-11-10:Fire hazard testing-Part 11-10: Test flames 50 W horizontal and vertical

flame test methods

Abstract摘要

Horizontal Testing (HB) - Method A

Procedure: A specimen is supported in a horizontal position and is tilted at 45°. A flame is applied to the end of the specimen for 30 seconds or until the flame reaches the 1 inch mark. If the specimen continues to burn after the removal of the flame, the time for the specimen to burn between the 1 and 4 inch marks are recorded. If the specimen stops burning before the flame spreads to the 4 inch mark, the time of combustion and damaged length between the two marks is recorded. Three specimens are tested for each thickness.

Vertical Testing (V-0, V-1, V-2) - Method B

Procedure: A specimen is supported in a vertical position and a flame is applied to the bottom of the specimen. The flame is applied for ten seconds and then removed until flaming stops at which time the flame

is reapplied for another ten seconds and then removed. Two sets of five specimens are tested. The two sets are conditioned under different conditions.

EN 60695-11-20:Fire Hazard Testing - Part 11-20: Test Flames - 500 W Flame Test

Methods

Abstract摘要

Specifies a small-scale laboratory screening procedure for comparing the relative burning behaviour of specimens made from plastics and other non-metallic materials, as well as their resistance to burn-through when exposed to a flame ignition source of 500 W nominal power. This method is applicable to both solid materials and cellular plastic materials having an apparent density of 250 kg/m3 or greater when determined in accordance with ISO 845. It does not apply to thin materials that shrink away from the applied flame without igniting, for which ISO 9773 should be used. The test method described is intended to characterize material performance, for example for quality-control purposes, and is not intended to assess the behaviour to fire of building materials or furnishings. It may be used for the pre-selection of a material, provided that positive results are obtained at a thickness which equals the smallest thickness used in the application. The results obtained provide some information about the behaviour of plastic materials in service, but can never by themselves assure safe performance in service. This test method provides a classification system which may be used for quality assurance or the pre-selection of component materials of products.
