ISO 20870 specifies laboratory procedures which are intended to imitate the effects of naturally-occurring reactions. The physical properties of interest are measured before and after the application of the specified treatments.

1. Scope 1.1 General This Guideline provides information and methodology to identify and evaluate hazards caused by earthquake forces acting on operational and functional components (OFCs) and to undertake appropriate mitigation strategies and techniques. It is important to note that seismic risk reduction of OFCs is affected by the structural performance of the building, although the…

This Technical Report provides information on the effect of water-soluble chloride and sulfate contamination levels on steel surfaces, before the application of paint or related products to surfaces prepared in accordance with standard mechanical or blast-cleaning surface preparation methods. NOTE The tolerance for water-soluble salt contamination may be different for different paint types. This…

Applies to working standard microphones with removable protection grids meeting the requirements of IEC 61094-4 and to laboratory standard microphones meeting the requirements of IEC 61094-1. Describes methods of determining the pressure sensitivity by comparison with either a laboratory standard microphone that has been calibrated according to IEC 61094-2, or another working standard…

A technical report for use by test houses and other users. It assists them with determining and recording verification of conformity of the equipment under test with the requirements of IEC61010-2-043 (1997). If the paper version of the report is ordered, a diskette is provided with fill-in tables for recording the test results. If the report is downloaded directly from the web, it consists of…

Four methods are described for measuring chromatic dispersion: (a) phase shift, (b) spectral group delay in the time domain, (c) differential phase shift, and (d) interferometry. Methods (a), (b) and (c) apply to class A1 graded-index multimode fibres and class B single-mode fibres. Method (d) applies to single-mode fibres, class B1 to B3 in the 1000 nm to 1700 nm wavelength range. The methods…

Applies to automatic and semi-automatic laboratory equipment for analysis and other purposes. Automatic and semi-automatic laboratory equipment consists of instruments or systems for measuring or modifying characteristics of samples, performing the process without manual intervention. Examples of such equipment are: analytical equipment, automatic sampler (e.g. pipettor), equipment for sample…

1.1 This part of ISO 5658 specifies an intermediate-scale method of test for measuring the vertical spread (upward and downward) of flame over a specimen of a product orientated in the vertical position. A measure of lateral spread can also be obtained. It provides data suitable for comparing the performance of materials, composites or assemblies, which are used as the exposed surfaces of walls…

This basic standard establishes the immunity requirements and a common reference for evaluating in a laboratory the performance of electrical and electronic equipment intended for residential, commercial and industrial application, as well as of equipment intended for electrical stations, as applicable. The purpose of this standard is to define: - test voltage and current waveforms; - ranges of…

This National Standard of Canada is equivalent to International Standard CEI/IEC 1000-4-4:1995, first edition, 1995-01, including Amendment 1:2000. This International Standard relates to the immunity requirements and test methods for electrical and electronic equipment to repetitive electrical fast transients. It additionally defines ranges of test levels and establishes test procedures.…
