Over deze norm
This part of ISO 2898-2 specifies the equipment and method to be used to prepare standard test specimens from plasticized compounds of homopolymers and copolymers of vinylchloride (VC). It also gives detailed instructions on the standard test methods and conditions to be used for determining the properties indicated in ISO 2898-1 for the purposes of designation, and other relevant properties. The properties and test conditions may be used in addition to identify a material and to control its quality in a reproducible manner. The properties of a moduled article depend, among other things, on the composition of the moulding material, on the shape and state of anisotropy of the moulding, and on the methods of test used. Anisotropy is a function of the moulding conditions, including the temperature, pressure, injection rase, etc. In addition, any post-treatment of the moduled article such as a conditioning or annaeling, will influence the values of the properties.
