The characteristics of PVC recyclates, given in Table 1, are divided into two types: — required characteristics needed to characterize PVC recyclates in general, and required for all recyclates; — optional characteristics needed to characterize PVC recyclates according to customer specifications and applications. These characteristics shall be assessed by using the test methods given in Table 1. A certificate of analysis giving the test results for each batch of recyclates shall be provided by the supplier to the purchaser upon request. NOTE Typical compositions of PVC compounds are given in Annex A. SIST EN 15346:2015

Typical compositions of PVC compounds Resins of vinyl chloride are always converted as compounds that composition depends upon the application. Typical compositions of compounds are given in Table A.1. PVC recyclates are made from these compounds.

Determination of bulk density B.1 General This test method specifies a method of determining the bulk density, i.e. the mass per unit of volume, of loose material (powder or granular material) that can be poured from a funnel of specific design. When the method is applied to relatively coarse materials, rather variable results might be obtained, owing to the error introduced when a straightedge blade is drawn across the top of the cylinder. A knowledge of bulk density is of limited value in estimating the relative fluffiness or bulk of moulding materials, unless their densities in the moulded condition are approximately the same. It therefore gives a fairly good idea of stability of mixing, presence of humidity and stability between batches (consistency).
