Specification of two methods for the determination of chlorine: Oxidation of the test portion with sodium peroxide (method A) in a Parr bomb or with gaseous oxygen (method B) in a flask, followed by electrometric or volumetric titration of the resulting chlorides. Blank tests shall be carried out by using the same quanities of reagents as in the determination.

Only suitable when the material to be tested is substantially uniform in thickness and flat or sufficiently flexible to remain flat in case of slight compression. Particularly suitable for materials having a very thin rubber layer which are difficult to test by stripping or peeling methods. However, it should be noted that the results obtained by this method will not necessarily correlate with those obtained by a stripping test. A figure shows the prepartion of test assembly.

Specification of a visual method of determining the number of impurities and foreign particles in polyvinylchloride resin. About 200 g of resin are flattened between a rigid white plate and a glass sheet containing a grid. The impurities and foreign particles visible in 25 squares (= 225 cm ) and having a diameter equal or greater than 0,250 mm are counted. Expression of the result by extrapolation as the number of specks per 100 squares of the grid.

The density of an unplasticised polyvinylchloride (PVC-U) pipe or -fitting, measured by the method described in ISO 1183, shall be between the limits of 1,35 gram per cubic centrimetre and 1,46 gram per cubic centrimetre. This does not apply to pipes made of compounds containing fillers or cellular products.

Applies primarily to ceelular materials having a sufficient compression resistance to permit suitable gripping of the test pieces. The test piece of a given shape is subjected to a tensile stress, transmitted to the test piece by means of a suitable device. The corresponding stress-strain curve shall be recorded. In the case of low compression resistance the bonding of reinforcing metall plates to the gripping ends of test pieces is possible.
