11、COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULPERFORMANCE5 General5.1 All polyurethane foam intended for use during the polyurethane smoldering and flaming tests outlinedin UL 217 and UL 268, are to be subject to all tests and results outlined
12、in this document. The ConeCalorimeter tests outlined in Section 7 and polyurethane smoldering and flaming tests outlined in UL 217and UL 268 are to be conducted using specified samples of foam. The foam used for validation testingshall come from the same batch of foam, (bun-run or bun) that will be
13、used for the polyurethanesmoldering and flaming tests as outlined in UL 217 and UL 268. Each batch of foam must be validatedprior to the material being used for UL 217 and UL 268 polyurethane flaming and smoldering tests.5.2 The tests outlined in this document shall be conducted on each batch of foa
14、m intended to be used forthe polyurethane smoldering and flaming tests outlined in UL 217 and UL 268, and shall be conducted inthe numerical order as outlined in this document.5.3 Each batch of foam shall be subject to validation testing consisting of at least 5 samples. At least onesample shall com
15、e from the front of the bun and one sample shall come from the end of each bun withthe balance of the samples being selected from throughout the bun.5.4 Foam test samples shall be cut with the longest sample dimension parallel to the bun machinedirection, with the top surface of the sample no less t
16、han 12 in. (30.5 cm) from top of bun, and sampleedges not less than 12 in. from bun sidewalls.5.5 The foam shall not consist of any colorants, whitening additives, fire retardant additives, orpost-production fire retardant additives.5.6 The foam shall have an Indentation Force Deformation (IFD) of 3

(4140 275 N/m2) 25% as determined by ASTM D 3574, Standard Test Methods for Flexible Cellular MaterialsSlab,Bonded, and Molded Urethane Foams, Test Method B1.5.7 The batch of foam can be used for polyurethane smoldering and flaming tests outlined in UL 217 andUL 268 if it complies
18、with all of the requirements and test results specified in Sections 5 10. Otherwise,the batch of foam shall not be used for polyurethane smoldering and flaming tests outlined in UL 217 andUL 268.NOVEMBER 15, 2013 UL 2852 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION
19、 WITHOUT PERMISSION FROM UL6 Conditioning6.1 All foam samples for cone calorimeter, smoldering and flaming tests shall be conditioned for aminimum of 30 days, at a temperature of 23 3ordm C (73.4 5.4ordm F), with a relative humidity of 5010%.6.2 Samples are to be removed from their shipping containe
20、rs/packaging during conditioning.7 Foam Material Density Specifications7.1 Polyurethane foam density shall be calculated and recorded using the following formula.Density = M (lbs) S (ft3)M (m) S (kg) (cm3)in which:M = mass of the sample in lbs 0.01 lbs (kg 4.54 g)S = Sample volume in cubic feet (ft3
