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…

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…

1.1 Organization and content This standard sets out the requirements for the design, manufacture, testing and inspection of non-refillable containers with a capacity of not more than 1 L and their selection and use for the handling, offering for transport and transport of UN1950, aerosols and UN2037, gas cartridges, in Canada. This standard consists of six main sets of requirements. Sections…

ISO 16962:2017 specifies a glow-discharge optical-emission spectrometric method for the determination of the thickness, mass per unit area and chemical composition of metallic surface coatings consisting of zinc- and/or aluminium-based materials. The alloying elements considered are nickel, iron, silicon, lead and antimony. This method is applicable to zinc contents between 0,01 mass % and 100…
