Plastics — Determination of bulk factor of moulding materials

This document specifies a method of determining the bulk factor of a moulding material based on the ratio of the apparent volumetric density of a given quantity of particles and the corresponding material density.

Plastiques — Détermination du facteur de contraction des matières à mouler

Polimerni materiali - Določanje "bulk" faktorja (razmerja med gostoto oblikovanega materiala in navidezno gostoto materiala za oblikovanje) materialov za oblikovanje

Ta dokument določa metodo za določanje faktorja gostote materiala za izdelavo kalupov na podlagi razmerja med navidezno prostorninsko gostoto določene količine delcev in ustrezno gostoto materiala.
