This document specifies a method whereby the heat of reaction generated during epoxy resin crosslinking is measured by differential scanning calorimetry (DSC). The degree of crosslinking is determined based on this result. This method is applicable to epoxy resin systems with a moderate or slow crosslinking-reaction speed. It might not be applicable to systems with a fast crosslinking-reaction speed at ambient temperature.

ISO 15064:2017 specifies methods for the measurement of toluene-2,6-diisocyanate in mixtures of the 2,4- and 2,6-isomers. Two methods based on infrared spectroscopy are used to give accurate results over a broad range of isomer concentrations. Method A is applicable to toluenediisocyanate (TDI) samples containing between 5 % and 95 % of the 2,6-isomer. Method B is applicable to TDI samples containing 0 % to 5 % of the 2,6-isomer. Both methods are based on the quantitative measurement of absorption bands arising from out-of-plane C−H deformation vibrations of the aromatic ring at 810 cm−1 and 782 cm−1 (12,3 μm and 13,8 μm).

ISO 14900:2017 specifies two methods for the measurement of the hydroxyl number of polyols used as polyurethane raw materials. It is necessary to know the hydroxyl content of polyols to properly formulate polyurethane systems. Method A is primarily applicable to readily esterified polyether polyols. It is also intended for polyols which have significant steric hindrance, such as those based on sugars. Method B is intended for polyether polyols, polymer polyols and amine-initiated polyols, but may give low results for sterically hindered polyols. Other polyols can be analysed by these methods if precautions are taken to verify applicability. These methods can be used for research and for quality control and specification purposes.

ISO 26603:2017 specifies the determination of the total chlorine content of aromatic isocyanates used in the preparation of polyurethanes. The difference between the total chlorine content and the hydrolyzable chlorine content (see ISO 15028) is a measure of the process solvents left in the product. Both test methods are applicable to a variety of organic compounds, including aliphatic isocyanates, but the amount of sample used might need to be adjusted. These test methods can be used for research or for quality control. NOTE This document is technically equivalent to ASTM D4661?03.

This International Standard specifies a method of determining the moulding shrinkage and the shrinkage after
heat treatment of moulded test specimens of thermosetting moulding materials.
These characteristics are useful for the production control of thermosetting material and for checking
uniformity of manufacture. Furthermore, knowledge of the initial shrinkage of thermosetting materials is
important for the construction of moulds, and knowledge of post-shrinkage for establishing the suitability of the
moulding material for the manufacture of moulded pieces with accurate dimensions.

Samples containing 0,3 % to 10 % of nitrogen have been evaluated by this method. The method is applicable to amine-based polyols, polyether polyols and polyether polyol blends that are used in polyurethane reactions. The results are measures of batch-to-batch uniformity and may be used to estimate reactivity in polyurethane reactions.

ISO 18872:2007 specifies procedures for determining the tensile properties of moulding and extrusion plastics over a wide range of strain rate, including high rates appropriate to impact-loading situations. Properties are determined through a combination of measurements at low and moderate strain rates, the use of mathematical functions to model these results, the rate-dependence of parameters and the determination of parameters at high strain rates by extrapolation. Tensile properties at high strain rates are then derived by calculation. In this way, the experimental problems and associated errors with the measurement of properties at high rates are avoided.
