This second edition cancels and replaces the first edition (i. e. ISO 3995:1977). The method subjects a compact pressed form metallic powder to a uniformly increasing transverse force under controlled conditions until fracture occurs. the green strength is determined on compacts either having a particular density or after compaction at a specific compacting pressure.

This document specifies a method for the determination of the relative loss of mass which a metallic powder undergoes when heated in a stream of pure dry hydrogen under specified conditions.
The purpose of this test is to evaluate a chemical powder characteristic which is of importance to the powder metallurgical industry. The test is not intended as a means for the determination of the content of specific elements (see Annex A and ISO 4491-1).
The test method is applicable to unalloyed, partially alloyed and completely alloyed powders of the metals listed in Table 1 (see 7.2.1). It is not applicable to lubricated powders or to mixtures of metal powders.

This document specifies a generic test method to determine the abrasion wear characteristics of hardmetals.
The test is appropriate for use in situations where test laboratories have a need to simulate abrasive damage. The procedure includes information which enables the test to be used in a variety of different conditions:
a) with counterface wheels of different stiffness (for example steel and rubber);
b) wet and dry;
c) different abrasive sizes;
d) different chemical environments.

This document gives guidelines for the measurement of hardmetal grain size by metallographic techniques only using optical or electron microscopy. It is intended for WC/Co hardmetals (also called cemented carbides or cermets) containing primarily tungsten carbide (WC[1]) as the hard phase. It is also intended for measuring the grain size and distribution by the linear-intercept technique.
This document essentially covers four main topics:
— calibration of microscopes, to underpin the accuracy of measurements;
— linear analysis techniques, to acquire sufficient statistically meaningful data;
— analysis methods, to calculate representative average values;
— reporting, to comply with modern quality requirements.
This document is supported by a measurement case study to illustrate the recommended techniques (see Annex A).
This document is not intended for the following:
— measurements of size distribution;
— recommendations on shape measurements. Further research is needed before recommendations for shape measurement can be given.
Measurements of coercivity are sometimes used for grain-size measurement, however, this document is concerned only with a metallographic measurement method. It is also written for hardmetals and not for characterizing powders. However, the method can, in principle, be used for measuring the average size of powders that are suitably mounted and sectioned.

This document specifies a method of measuring the air permeability and the porosity of a packed bed of metal powder, and of deriving therefrom the value of the envelope-specific surface area. The permeability is determined under steady-state flow conditions, using a laminar flow of air at a pressure near atmospheric. This document does not include the measurement of permeability by a constant volume method.
Several different methods have been proposed for this determination, and several test devices are available commercially. They give similar, reproducible results, provided that the general instructions given in this document are respected, and the test parameters are identical.
This document does not specify a particular commercial test device and corresponding test procedure. However, for the convenience of the user, an informative annex has been included (see Annex A) which is intended to give some practical information on three specific methods:
— the Lea and Nurse method, involving a test device which can be built in a laboratory (see A.1);
— the Zhang Ruifu method, using a similar test device (see A.2);
— the Gooden and Smith method, involving a test device which can be built in a laboratory but for which a commercial test device also exists. (Two types of commercial test device exist; one of these is no longer available for purchase, but is still being used, see A.3.)
These methods are given as examples only. Other test devices available in various countries are acceptable within the scope of this document.
This testing method is applicable to all metallic powders, including powders for hardmetals, up to 1 000 µm in diameter, but it is generally used for particles having diameters between 0,2 µm and 75,0 µm. It is not intended to be used for powders composed of particles whose shape is far from equiaxial, i.e. flakes or fibres, unless specifically agreed upon between the parties concerned.
This testing method is not applicable to mixtures of different metallic powders or powders containing binders or lubricant.
If the powder contains agglomerates, the measured surface area can be affected by the degree of agglomeration. If the powder is subjected to a de-agglomeration treatment (see Annex B), the method used is to be agreed upon between the parties concerned.

The method is intended for metallic powders that flow freely through a 2,5 mm diameter orifice. It can, however, be used for powders that flow with difficulty through a 2,5 mm diameter orifice but flow through a 5 mm diameter orifice.
Methods for the determination of the apparent density of powders that will not flow through a 5 mm diameter orifice are specified in ISO 3923‑2[1].
