Plastics — Determination of temperature of deflection under load — Part 3: High-strength thermosetti...
ISO 75-3:2004 specifies a method for the determination of the temperature of deflection under load of high-strength thermosetting laminates and compression-moulded long-fibre-reinforced plastics in which the fibre length is greater than 7,5 mm. The flexural stress used is not fixed, as in ISO 75-2, but is a fraction (1/1000) of the initial (room-temperature) flexural modulus of the material under…
Textiles — Determination of deodorant property — Part 6: Gas chromatography method using automated d...
This document specifies a gas chromatography test method for the deodorant testing of all textile products. This method applies to the odour component chemicals, such as indole, isovaleric acid, and nonenal. Two methods are described in this test method:
— Single Analysis (Single Cycle) an odour chemical is applied in a container avoiding contact with a specimen in method A. Each chemical…
