Paper, board and pulps — Standard atmosphere for conditioning and testing and procedure for monitori...
Specifies the standard atmosphere for conditioning and testing pulp, paper, and board, and also the procedures for measuring the temperature and relative humidity. For the conditioning of laboratory prepared handsheets in accordance with ISO 5269-1, the standard atmosphere is that defined in this standard, but the procedure is different. Annex A covers the measurement of temperature and relative…
Crude petroleum — Determination of water and sediment — Centrifuge method
Specifies a method for the laboratory determination. The precision data of this procedure have only been determined for water contents up to 1 % (V/V). Includes principle, apparatus, reagents, sampling, procedure, expression of results, precision and test report. A centrifuge tube is shown in figure 1. The procedure for reading the volume of water and sediment is shown in figure 2. The precision…
Adhesives — Guide to the selection of standard laboratory ageing conditions for testing bonded joint...
Describes conditions under which adhesive joints may be exposed to various climatic or chemical influences for the purpose of assessing the effects of such influences on certain properties. They are not necessarily applicable to the determination of the service life of a bonded assembly. The principle consists in defining the ageing conditions that relate most closely to the application for the…
Laboratory glassware — Thermal shock and thermal shock endurance — Test methods
Specifies a thermal shock test and the procedure for determining the thermal shock endurance. Does not apply to fused silica ware and annealed containers made from soda-lime-silicate glass.
Applies to surgeons' and laboratory coats made from preshrunk,
bleached cotton drill fabric. They shall not be worn in an
environment requiring lint-free clothing.
Protective clothing — Protection against liquid chemicals — Determination of resistance of air-imper...
Describes a laboratory test method that enables an assessment to be made of the resistance to permeation by liquids afforded by clothing materials, used for industrial and agricultural applications. The test does not necessarily simulate conditions that may occur in practice.
