This document specifies methods for determination of the ash of polyamides, both filled and unfilled.
The general procedures given in ISO 3451-1 are followed. For unfilled materials method A and method D or method C of ISO 3451-1:2019 is used. For filled and glass-fibre reinforced materials method A and method D of ISO 3451-1:2019 is used.
For glass-fibre filled materials containing flame retardant, antimony trioxide, and/or other, volatilizable, additives such as pigment zinc sulfide, a modification is incorporated to remove these as volatile bromine component(s).

This document describes the background to methods for the determination of the thermal conductivity and thermal diffusivity of polymeric materials. Different techniques are available for these measurements and some may be better suited than others for a particular type, state and form of material. This document provides a broad overview of these techniques. Standards specific to these techniques, as referenced in this document, are used to carry out the actual test method.

This International Standard specifies the apparatus, the test solutions, and the procedure to be used in conducting the electrochemical tests for 1) assessment of the Fick's diffusion parameter for protective coating on metallic materials and 2) for the estimation of the galvanic corrosion rates with the conversion of ISO 21746 coating-free sample data.

This International Standard applies to the measurement of crack tip position and crack propagation on the bonding surface of carbon fibre reinforced plastic (CFRPs) and metal assemblies bonded panels.
This document does not apply to the visualization measurement of strain distribution or defects during load application to specimens.
