Water quality — Sampling — Part 3: Guidance on the preservation and handling of samples
Gives general guidelines on the precautions to be taken to preserve and transport water samples (filling the container, use of appropriate containers, preparation of containers, cooling or freezing of the samples, filtration or centrifuging of samples, techniques generally suitable for the preservation of samples). These guidelines are particularly appropriate when a sample (spot or composite…
Optics and optical instruments — Veiling glare of image forming systems — Definitions and methods of...
Adopts both the veiling glare index (VGI) and the glare spread function (GSF) as measures of the veiling glare characteristics of optical and electrooptical imaging systems. Laboratory measurement techniques are described in general terms and recommendations are made regarding the performance of the main subunits of the equipment. The measurement techniques described are chiefly valid for the…
Insulators of ceramic material or glass for overhead lines with a nominal voltage greater than 1000 ...
Deals with puncture testing of ceramic and glass insulator units of class B only.
This document is intended for use by insulator buyers and manufacturers, test and research laboratories, and can be used as a direct replacement for thepuncture test in oil specified in IEC 60383-1.
Road vehicles — Air filters for passenger compartments — Part 1: Test for particle filtration
Specifies assessment criteria in order to permit the selection and comparability of air filters and filter elements under laboratory conditions. Applies to air filters used in motor vehicles to remove dust particles from the external air or recirculated air for the passenger compartment. The tests provide information on pressure differences, the filtration rate and fractional filtration rate, as…
Plastics — Methods of exposure to laboratory light sources — Part 4: Open-flame carbon-arc lamps
Specifies methods for exposing to a carbon-arc light source under controlled environmental conditions. The procedure may include measurements of the irradiance and radiant exposure at the surface of the specimen. It is recommended that a similar material of known behaviour be exposed simultaneously with the experimental material as a reference. General guidance is given in ISO 4892-1.
Plastics — Methods of exposure to laboratory light sources — Part 2: Xenon-arc sources
Specifies methods for exposing to a xenon-arc light source under controlled environmental conditions. The procedure may include measurements of the irradiance and radiant exposure at the surface of the specimen. It is recommended that a similar material of known behaviour be exposed simultaneously with the experimental material as a reference. A xenon arc, when fitted with suitable filters,…
Rotary tools for threaded fasteners — Performance test method
Specifies a laboratory performance test method for power assembly tools for installing threaded fasteners. Gives instructions on what to test for and how to evaluate and present the test data. Is applicable to tools which apply torque continuously, i.e. does not apply e.g. to impact and ratchet wrenches.
