19、European Standard specifies a method for determining the volatile loss in mass of polyvinyl chloride floor coverings. 2 Principle The percentage loss of mass of a test piece taken from the suiface layer of a material during a specified heat treatment in the presence of an absorbent mateiial is measu
20、red. 3 Apparatus and materials at (100 f 2) OC. 3.1 A eizti2ttc.d men, capable of being maintained Page 3 EN 664 : 1994 6 Procedure Weigh each test piece separately and record the mass. Place the test piece in a metal dish. Csing new charcoal for each test, pour approximately 120 O00 min3 of activat
21、ed charcoal into the bottom of the container. Place the dish on the charcoal and cover with a further 120 000 MIT? of charcoal. Repeat this procedure for the two other test pieces, then place the perforated cover on the container. Place the container in the oven which has previously been brought up
22、to a temperature of 100 OC. Six hours later: remove the test pieces, leave them to cool for 24 h in the standard atmosphere and then weigh them again. 3.2 A metal coiztctitzeii; of volume approximately 900 O00 min3. with nerforatecl cover. 7 Calculation and expression of results 3.3 Metal mesh cimul
23、m clisiws, with approximately 1 hole per min2; diameter 60 mm, height approximately 6 mm. 3.4 Activated chwcoctl, free of powder, grain size (4 to 6) min, of uniform type and quality. The charcoal, sieved and dried at 70 OC (preferably in a vacuum) to a constant niass, shall be kept in a hermeticall
24、y sealed container. 3.5 A balatzm with a sensitivity of 1 mg. 4 Sampling and preparation of test pieces Pake a representative sample from the available material. Pake three test pieces peeled or cut from the surface layer of the sample, the distance between the outer edge of the sample and the neare
25、st edge of the test pieces being at least 100 mm, of minimum area 2000 mm2. 5 Conditioning Condition the test pieces at a temperature of (23 f 2) OC and relative humidity of (50 f 5) % for a minimum of 24 h. Maintain these conditions when carrying out the test. Express the change in mass loss as a p
26、ercentage of the original mass for each test piece. Calculate the mean value for volatile loss for the three test pieces. 8 Test report The test report shall include the following information: a) a reference to this standard, i.e. EN 664; b) a complete identification of the product tested, including
27、 type, source, manufacturers reference nuinbeis; e) the previous histoiy of the sample; d) the mean valiie for volatile loss; e) any deviation from this standard which may have affected the results.
