20、I 07-1999 Foreword This European Standard has been prepared by Technical Committee CEN/TC 155, Plastics piping systems and ducting systems, the Secretariat of which is held by NNI. This standard is based on a document prepared by TC 138/SC 1 AHG, PVC Material, from the International Organization for
21、 Standardization (ISO). This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 1999, and conflicting national standards shall be withdrawn at the latest by June 1999. According to the CEN/CENELEC In
22、ternal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerla
23、nd and the United Kingdom. This standard is one of a series of standards on test methods which support System Standards for plastics piping systems and ducting systems.

24、07-1999 1 Scope This standard specifies a method for assessing the poly(vinyl chloride) (PVC) content in reprocessable and recyclable unplasticized (PVC-U) materials or materials derived from PVC-U products. In this standard, only the method for calculation of the PVC content is described, while for
25、 the determination of the chlorine content reference is made to prEN ISO 1158:1997. If the material contains or is supposed to contain chlorinated poly(vinyl chloride) (PVC-C) or chlorinated polyethylene (PE-C), an apparent PVC content is calculated. 2 Normative references This standard incorporates
26、 by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to, or revisions of, any of these publications apply to this standard
27、only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies. prEN ISO 1158:1997, Plastics Vinyl chloride homopolymers and copolymers Determination of chloride. (ISO/DIS 1158:1997) EN ISO 3451-5:1996, Plastics Determination
28、of ash Part 5: Poly(vinyl chloride). (ISO 3451-5:1989) 3 Principle An assessment of the PVC content, taking into account the presence of fillers, additives and, if applicable, other polymers, is made by calculation based on the chlorine content determined in accordance with prEN ISO 1158:1997. NOTEI
29、t is assumed that the following test parameter is set by the standard making reference to this standard: the sampling procedure, applicable to pipes, fittings or material (see clause 4). 4 Test pieces Test pieces, appropriate to the method(s) used (see clause 5 and associated notes), shall be prepar
30、ed, from samples taken in accordance with the referring standard, from a pipe, fitting or material, as applicable. 5 Procedure 5.1 Determination of chlorine content Determine the chlorine content, mCl, in accordance with prEN ISO 1158:1997, or any other analytical method giving equivalent results. N
31、OTEMethods using infra-red analysis or X-ray analysis may be suitable. In case of dispute, the method given in prEN ISO 1158:1997 shall be used. 5.2 Calculation of the PVC content or apparent PVC content Calculate the PVC content or the apparent PVC content, in percentage by mass, mv, using the foll
32、owing equation: mv=3 100 mCl 56,8 where mClis the chlorine content expressed as a percentage by mass in accordance with clause 7 of prEN ISO 1158:1997. NOTEIf the material under analysis contains PVC-C, PE-C or chlorine-free polymers, the calculated PVC content may deviate from the actual PVC conten
33、t. 5.3 Determination of filler content Determine the filler content, in percentage by mass, mf, in accordance with EN ISO 3451-5:1996, or any other analytical method giving equivalent results. NOTE 1Other fillers may also be present. NOTE 2Methods using infra-red analysis, X-ray analysis or chemical
34、 analysis may be suitable. In case of dispute, the method given in EN ISO 3451-5:1996 shall be used. 5.4 Validation of composition 5.4.1 Check the validity of mvand mfby calculating the sum of PVC, filler and additive contents, M, in percentage by mass, using the following equation: M = mv+ mf+ 2 wh
35、ere mvis the PVC content; mfis the filler content. NOTE 1It is assumed that the combined amount of additives incorporated (e.g. pigments, stabilizers and lubricants) is at least 2 % by mass. If M 97 %, continue in accordance with 5.4.2. If M $ 97 %, calculate the PVC content mv, in percentage by mas
36、s, using the following equation: mv= 100 2 (mf+ 2) NOTE 2In this case, PVC-C or PVC-C/ABS blends may be present. These blends are considered not to have a detrimental effect on PVC products and therefore are counted as PVC-U. 5.4.2 If M 97 %, the material may contain one or more of the following: PE
37、-C in large quantities; other (chlorine-free) polymers; additives in excess of 2 % by mass. In such cases, determine by infra-red or X-ray analysis whether chlorine-free polymers or additives are present and proceed in accordance with a) or b), as applicable. The infra-red or X-ray analysis equipmen
38、t shall be calibrated in accordance with the manufacturers instructions before testing.

39、ther than PE-C are present, calculate the PVC and PE-C contents, mvand mE, by solving the following simultaneous equations: mE+ mv+ mf+ 2 = 100 0,37mE+ 0,57mv= mCl* where mCl*is the chlorine content, in percentage by mass of the polymeric parts, calculated by using the following equation: mCl*= mCl3
40、 100 100 2 mf b) If additives in excess of 2 % or other polymers are found, take the PVC content to be equal to the apparent PVC content (see 5.2). 6 Test report The test report shall include the following information: a) a reference to this standard and to the referring standard; b) a full identifi
41、cation of the material under test; c) a description of the sampling procedure used; d) identification of the analytical methods used; e) list of the measured and calculated values in percentage by mass; f) any factors which may have affected the results, such as any incidents or any operating detail
42、s not specified in this standard; g) the date of the test.
