Lays down the principles for the design of the apparatus and minimum requirement that shall be met for determination of the laboratory steady-state thermal transmission properties of building components and similar components for industrial use. Does not specify a particular design. Describes also the apparatus, measurement technique and necessary data reporting. Primarily intended for laboratory…

This National Standard of Canada is equivalent to International Standard ISO 2157:1992. 1 Scope This International Standard specifies the nominal diameters of the working parts of dental rotary instruments, for example burs, laboratory burs, grinding instruments, diamond instruments, mandrels, etc. and the corresponding designation. It does not cover the diameters of root canal…

This National Standard of Canada is equivalent to International Standard ISo 7786:1990. 1 Scope This International Standard specifies the dimensional and other requirements for grinding instruments used in the dental laboratory. Other characteristics of dental abrasive instruments are not covered by this International Standard. These will be dealt with in a future International…

Cancels and replaces the first edition (1974) and amendment 1 (1994). Specifies a method for the determination of the density of natural rubber latex concentrate between the temperatures of 5 °C und 40 °C. Intended for use when density determinations are used to calculate the mass of a measured volume of latex in locations where it is not practical to weigh directly or to control the temperature…

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…

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…

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.

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…

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.

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,…
