Sintered metal materials, excluding hardmetals - Determination of transverse rupture strength (ISO 3325:2026)
Käsitlusala:
This document specifies a method for the determination of the transverse rupture strength of sintered metal materials, excluding hardmetals. The method is particularly suitable for comparing the sintered strength of a batch of metal powder with that of a reference powder or with a reference strength.
The method is applicable to sintered metal materials, excluding hardmetals, whether they have been subjected to heat treatment after sintering or not, and also to materials that have been sized or coined after sintering.
It is especially suitable for materials having a uniform hardness throughout their section and negligible ductility, i.e. a ductility corresponding to a permanent deformation of less than about 0,5 mm measured between the two supports during the transverse rupture strength determination.
NOTE The permanent deformation can be measured with sufficient precision from the two fragments of the broken or cracked bar by indexing the lower surface. Alternatively, the deflection of a straight line drawn horizontally on the side of the test piece can be measured using an optical instrument such as a measuring microscope or optical comparator.

Hardmetals - Palmqvist toughness test (ISO 28079:2026)
Käsitlusala:
This document specifies a method for measuring the Palmqvist toughness of hardmetals and cermets at room temperature by an indentation method. This document is applicable to a measurement of toughness, called Palmqvist toughness, calculated from the total length of cracks emanating from the corners of a Vickers hardness indentation, and it is intended for use with metal-bonded carbides and carbonitrides (normally called hardmetals, cermets or cemented carbides). The test procedures specified in this document are applicable for use at ambient temperatures, but can be extended to higher or lower temperatures by agreement. The test procedures specified in this document are also applicable for use in a normal laboratory-air environment. This document is not applicable for use in corrosive environments, such as strong acids or seawater.

Corrosion of metals and alloys — Determination of resistance to stress corrosion cracking of copper and copper-zinc alloys in ammonia vapour
Käsitlusala:
This document specifies a method for the determination of resistance to stress corrosion cracking (SCC) of copper and copper-zinc alloys in ammonia vapour.
This document covers the method of sampling, the types of specimens, the loading procedure, the type of environment and the interpretation of results.
This document is aimed at determining resistance to SCC as a function of the chemical composition, the method of manufacture of copper and copper-zinc alloys.
This document applies to wrought copper and copper-zinc alloys in the form of products and parts.
This document can be used to rank materials performance and select candidate materials under atmospheres containing ammonia. However, the results of this test should not be considered as an absolute criterion for the quality of alloys.
This document specifies a method for exposing test specimens in ammonia vapour coexisting with an aqueous ammonia solution and specifies the environmental conditions and test procedures.
This document specifies two methods of loading:
under constant total strain;
under constant load.
It does not cover slow strain rate test methods and determination of maximum admissible stress by the method of permanent deformation for copper and copper-zinc alloys, although an effort is now being made to apply such methods to these alloys (see ISO 7539-7).
