Environmental testing - Part 2-69: Tests - Test Te/Tc: Solderability testing of electronic component...
IEC 60068-2-69:2017 outlines test Te/Tc, the solder bath wetting balance method and the solder globule wetting balance method to determine, quantitatively, the solderability of the terminations. Data obtained by these methods are not intended to be used as absolute quantitative data for pass–fail purposes.
The procedures describe the solder bath wetting balance method and the solder globule…
Wind energy generation systems - Part 12-1: Power performance measurements of electricity producing ...
IEC 61400-12-1:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC 61400-12-1:2017 specifies a procedure for measuring the power performance characteristics of a single wind…
Wind energy generation systems - Part 12-1: Power performance measurements of electricity producing ...
IEC 61400-12-1:2017 specifies a procedure for measuring the power performance characteristics of a single wind turbine and applies to the testing of wind turbines of all types and sizes connected to the electrical power network. In addition, this standard describes a procedure to be used to determine the power performance characteristics of small wind turbines (as defined in IEC 61400-2) when…
Iron ores — Determination of sulfur content — Part 2: Combustion/titration method
ISO 4689-2:2017 specifies a combustion/titration method for the determination of the sulfur content of iron ores.
This method is applicable to sulfur contents between 0,002 % (mass fraction) and 0,25 % (mass fraction) in natural iron ores, iron ore concentrates, and agglomerates, including sinter products. The results are not affected by the presence of fluoride.
Iron ores — Determination of sulfur content — Part 3: Combustion/infrared method
ISO 4689-3:2017 specifies a combustion/infrared method, using a high-frequency induction furnace, for the determination of the sulfur content of iron ores.
This method is applicable to sulfur contents between 0,002 % (mass fraction) and 0,25 % (mass fraction) in natural iron ores, iron ore concentrates and agglomerates, including sinter products. The method is not applicable to iron ores…
Plastics — Polyols for use in the production of polyurethane — Determination of hydroxyl number
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…
Plastics — Aromatic isocyanates for use in the production of polyurethanes — Determination of total ...
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…
Aerosol containers and gas cartridges for transport of dangerous goods
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.
