Layouts for standards — Part 4: Standard for atomic absorption spectrometric analysis
Establishes a layout for standard methods of analysis and gives some recommendations for their presentation and wording. This layout involves the use of appropriate terminology, indicated in ISO 6955. Supplements ISO 6956, which summarizes the principle of atomic absorption.
Asbestos-cement products — Part 1: Corrugated sheets and fittings for roofing and cladding
Specifies the characteristics or straight asbestos-cement corrugated sheets and their asbestos-cement fittings to be used for roofing and cladding. Specifies also the checking of these characteristics as well as marking and conditions of acceptance. By agreement between manufacturer and purchaser certain requiremants can apply to curved corrugates sheets. Is not applicable to asymmetrical section…
Surface active agents — Determination of the power to disperse calcium soap — Acidimetric method (Mo...
A 0,5 % (m/m) aqueous soap solution is prepared, and after maintaining this at testing temperature for 24 h, an aliquot portion of this solution is taken. This aliquot portion is mixed with a dilute solution of the dispersing agent (surface active agent) and subsequently with a specified volume of water of known calcium hardness. The mixture is maintained for 1 h at the testing temperature and…
Surface active agents — Determination of mineral sulfate content — Titrimetric method
A buffered acetonic solution of a test portion is titrated with a standard volumetric lead(II) nitrate solution in the presence of dithizone as indicator. The method is applicable to anionic surface active agents, containing sodium, ammonium and alkanolamine sulphates. It is not applicable to products containing other compounds such as phosphates or large amounts of chloride nor is it applicable…
Aerials for the reception of sound and television broadcasting in the frequency range 30 MHz to 1 GH...
Applies to linearly polarized receiving aerials for domestic use in the frequency range 30 MHz to 1 GHz. Ensures uniformity in the presentation of aerial performance specifications and provides a standard format for individual aerial specification sheets. This publication supersedes IEC 60138 (1962).
Equipment for continuously monitoring radioactivity in gaseous effluents. Part 2: Specific requireme...
Gives specific standard requirements, technical characteristics, general test conditions and examples of acceptable methods for aerosol effluent monitors designed to measure the concentration of radioactivity emitted in gaseous effluents in the form of aerosols and its variations as a function of time and to actuate an alarm signal when a predetermined concentration is exceeded.
Applies to CAMAC systems as defined in IEC 60516. The generic standard for BASIC includes a real-time enhancement which is necessarily general. This standard defines specific syntax and semantics for use with CAMAC.
Safety logic assemblies of nuclear power plants - Characteristics and test methods
Includes principles of design, construction and testing of safety logic assemblies used in protection systems. Gives recommendations for the implementation of the general principles of nuclear reactor instrumentation in IEC 60231A. It includes provisions for acceptance and in-service testing reliability criteria and protection from external influences. Safety logic functions performed within the…
Abbreviations for Scientific and Engineering Terms
1. Scope
This Standard establishes abbreviations for words and word combinations for use
on drawings and in engineering and scientific writing. The purpose is not to
promote the use of abbreviations but to establish standard abbreviations to be
used when abbreviations are necessary. This Standard also includes commonly
used SI units. (See the Bibliography for a list of related standards…
Formsets for Use with Embossed Cards and Imprinting Equipment
1. Scope
1.1 The purpose of this Standard is to define common media for the transferring of information from sources, including the embossed characters on a card, by means of imprinting equipment.
1.2 The existence of two standards in relation to formset dimensions is recognized as are the several different methods of capturing the information contained on completed formsets.
1.3…
