Accuracy (trueness and precision) of measurement methods and results — Part 4: Basic methods for the...
Provides basic methods for estimating the bias of a measurement method and the laboratory bias when a measurement method is applied. In order that the measurements are made in the same way, it is important that the measurement method has been standardized. Can be applied only if the accepted reference value can be established as a conventional true value, e.g. by measurement standards or suitable…
Accuracy (trueness and precision) of measurement methods and results — Part 6: Use in practice of ac...
The purpose is to give some indications of the way in which accuracy data can be used in various practical situations by: giving a standard method of calculating the repeatability limit, the reproducibility limit and other limits, providing a way of checking the acceptability of test results obtained under repeatability or reproducibility conditions, describing how to assess the stability of…
Hand-held portable power tools — Measurement of vibrations at the handle — Part 4: Grinders
The method specified is a laboratory type-test procedure for establishing the magnitude of vibration in the handle of a power tool fitted with a specified test wheel. Applies to power tools that may be pneumatically driven or driven by other means. It is intended that the results be used to compare different models of the same type of power tool, i.e. power tools intended for use with the same…
Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-0...
Applies to hand-held and hand-manipulated CURRENT CLAMPS. These CURRENT CLAMPS are for use in the measurement of current without interruption of the current path of the circuit in which it is measured. They may be stand-alone CURRENT CLAMPS which are themselves within the scope of part 1, or accessories to other equipment within the scope of part 1. This standard does not apply to current…
Hand-held portable power tools — Measurement of vibrations at the handle — Part 6: Impact drills
Specifies a laboratory method of measuring the vibrations occurring at the handles of hand-held power driven impact drills. It is a type test procedure for establishing the magnitude of vibrations at the handles of impact drills operating under a specified load. It is intended that the results can be used to compare different power tools or different models of the same type of power tool.
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…
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…
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…
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,…
