ISO 60 — Plastics — Determination of Apparent Density of Material that can be Poured from a Specified Funnel – Testing Equipment
1 SCOPE AND FIELD OF APPLICATION This International Standard specifies a method of determining the apparent density, i.e. the mass per unit of volume, of base material (powder or granular material) that can be poured from a funnel of specified design. NOTE: For a method of degerming the apparent density of loose moulding maternal that…
ISO 3451-1 Plastics — Determination of Ash —Part 1: General methods – Testing Equipment
4 PrincipleIt is possible to determine the ash of an organic material by three main methods:a) Direct calcination, i.e. by burning the organic matter and heating the residue at high temperature untilconstant mass is reached (method A).b) Calcination after sulfation, which may be carried out by two different procedures:⎯ With sulfuric acid treatment after burning,…

Differential Scanning Calorimetry – Analysis of Polymer Mixture
First thing we need to do is to analyze pure polymer. In this example, polymers A and B are heated up in DSC, and the heat for melting is recorded. It is a specific enthalpy meaning measurement is presented as per mg of material. We use this information to quantify the mixture contents. Here is…
