ISO 28079:2009 specifies a method for measuring the Palmqvist toughness of hardmetals and cermets at room temperature by an indentation method. ISO 28079:2009 applies 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 proposed in ISO 28079:2009 are intended for use at ambient temperatures, but can be extended to higher or lower temperatures by agreement. The test procedures proposed in ISO 28079:2009 are also intended for use in a normal laboratory-air environment. They are not intended for use in corrosive environments, such as strong acids or seawater.

This document specifies a procedure to determine the release of metals from metallic materials used in products intended to come into contact with drinking water. The test can be used for three purposes: a) To assess a material as a reference material for a new category of materials by metal release testing using the results of several investigations in different waters covering a broad range of water compositions; b) To assess a material for an existing category for approval by way of metal release testing using the water defined in part 2, which exhibited the highest metal release when the reference material of the category was tested; c) To obtain data on the interaction of local water with a material.

 

This document specifies a method for the measurement of focal spot dimensions within the range of 5 µm to 300 µm of X-ray systems up to and including 225 kV tube voltage. This determination is based on the evaluation of an image with a dedicated focal spot that has been radiographically recorded using an edge and evaluated with a digital method. The imaging quality and the resolution of X-ray images depend highly on the characteristics of the effective focal spot, in particular the size and the two-dimensional intensity distribution as seen from the detector plane. For the characterization of commercial X-ray tube types (i.e. for advertising or trade) the specific maximum values of Annex A are preferred. NOTE The same procedure can be used at higher kilovoltages by agreement but the accuracy of the measurement can be poorer.
