This European Standard shal be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 1995, and conflicting national standa
15、rds shall be withdrawn at the latest by May 1995.

16、Spain, Sweden, Switzerland and United Kingdom. 1 Scope This 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
17、 treatment in the presence of an absorbent mateiial is measured. 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 charco
18、al for each test, pour approximately 120 O00 min3 of activated 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
19、 container in the oven which has previously been brought up 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.
20、7 Calculation and expression of results 3.3 Metal mesh cimulm 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
21、 vacuum) to a constant niass, shall be kept in a hermetically 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
22、 distance between the outer edge of the sample and the nearest 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 c
23、arrying out the test. Express the change in mass loss as a percentage 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
24、) a complete identification of the product tested, including 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.
