ISO 17662:2016 specifies requirements for calibration, verification and validation of equipment used for - control of process variables during fabrication, and - control of the properties of equipment used for welding or welding allied processes where the resulting output cannot be readily or economically documented by subsequent monitoring, inspection and testing. This involves process…

This international standard specifies the physical, chemical and microbiological requirements for and test methods of oxidized starch.

This document specifies the encapsulation of image formats specified in the JPEG 2000 family of Recommendations | International Standards in the framework defined in ISO/IEC 23008-12.

This International Standard specifies a method for the determination of the chlorine and bromine content of liquid petroleum products, synthetic oils and fluids, and additives for petroleum products (including used oils) that are soluble in organic solvents of negligible or accurately known chlorine/bromine content. The method is applicable to products or additives having chlorine contents in the…

This International Standard proposal specifies technical requirements and evaluation method for temperature correction on temperature measurement in radiosonde due to solar radiation in sounding experiment. This International Standard is applicable to the correction of temperature measurement traceable to SI unit in radiosonde boom sensors according to variations of pressure and air speed under…

The purpose of this International Standard is to provide a test method for the calibration of radiosonde humidity sensors with varying temperature and relative humidity using laboratory setups. The main scope of this International Standard is as follows: a) Technical requirements for laboratory setups needed for the calibration of radiosonde humidity sensors. b) Test procedure for calibrating…

Basis for this method is the laboratory sample obtained by the method specified in ISO 948. The principle of determination consists in grinding the laboratory sample, which has been previously mixed, to obtain particles of the size specified in the International Standard appropriate to the spice or condiment concerned or, if not so specified, to obtain particles of size approximately 1 mm.

This document provides guidance on the characterization of wood chips produced from raw materials, as defined in ISO 17225-4, for the following aspects: —    quality classes and specifications; —    sampling, sample preparation and test methods for physical characteristics which can be conducted on site; —    practical information about testing to be carried out by external laboratories. This…

ISO 10121-2:2013 aims to provide an objective test method to estimate the performance of any full size gas filtration device (GPACD) for general filtration regardless of media or technique used in the device. In fact, the goal of this part of ISO 10121 is to avoid relating the test data to internal parameters altogether. The benefit with this approach is that customers of GPACDs will be able to…

ISO 8642:2008 specifies test methods for metric self-locking nuts with MJ threads intended for use in aerospace construction at maximum operating temperature greater than 425 °C. It describes the test device and the method for each test. ISO 8642:2008 applies to self-locking nuts as defined above, provided that the relevant documents (dimensional standard, drawing, procurement specification, etc…
