This document contains phrasings and formats that are appropriate to the structure and character of an International Standard but which, in terms of detail, do n

The DIN Standard corresponding to the International Standard referred to in this document is as follows: ISO 139 DIN EN ISO 139 Amendments This s
9、tandard differs from DIN 54316:1983-10 as follows: a) the content of ISO 3415:1986 has been adopted in its entirety; b) the thickness after loading is to be measured after recovery periods of 15 min, 30 min and 60 min; c) test results according to this standard are comparable to those received on th

11、tic loading 48 Procedure 9.2 Using the values determined as described in 9.1, calculate the following values for all specimens : 8.1 General a) the thickness loss as the differente between the initial thi ckness and the thickness under the p Iressure of 220 kPa; Conduct the test in the Standard atmo
12、sphere for testing textiles. Make all determinations of thickness to the nearest 0,l mm. b) the thickness loss after recovery as the differentes be- tween the initial thickness and the three values of thickness after recovery for 15, 30 and 60 min. In Order to ensure that the specimen is held flat,
13、place a guard ring centrally on the specimen so that its centre coincides with that of the presser foot. Keep the guard ring in the same posi- tion throughout the entire test procedure. The ability of recovery of a textile floor covering tan be indicated by a diagram showing the remaining compressio

Measurement of thickness under pressure Thickness under the pressure of 220 kPa 5,6 mm Immediately after the determination of the initial thickness (see 8.2) apply a pressure of 220 kPa to the specimen without shock. Ensure that the specimen is neither touched nor move
16、d during the procedure. After exerting this pressure for a period of 2 h, measure the thickness under that pressure. Then remove the pressure on the specimen without touching or removing the specimen. Thickness after 60 min recovery 9,l mm Thickness loss 10,3 - 5,6 = 4,7 mm Thickness loss after reco
