JIS K7112塑料.非泡沫塑料密度和相对密度的测定方法—适用范围

This document specifies three methods for the determination of the density of non-cellular plastics in the form of void-free moulded or extruded objects, as well as powders, flakes and granules. Method A: Immersion method, for solid plastics (except for powders) in void‑free form. Method B: Liquid pycnometer method, for particles, powders, flakes, granules or small pieces of finished parts. Method C: Titration method, for plastics in any void‑free form.
