Soil quality — Guidance on laboratory testing for biodegradation of organic chemicals in soil under ...
Provides guidance on the selection and conduct of appropriate test methods for the determination of biodegradation of organic chemicals in aerobic soils. Does not describe any specific test method.
Thermal insulation — Determination of steady-state thermal transmission properties — Calibrated and ...
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…
Dental Rotary Instruments - Nominal Diameters and Designation Code Number
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…
Rubber latex — Determination of density between 5 degrees C and 40 degrees C
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…
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.
