Aircraft — Fire-resisting electrical cables — Methods of test
Specifies the tests suitable for establishing the compliance of cables with the performance requirements stated in ISO 2155. Is intended to serve as a basis for test specifications to be included in the relevant national standards when the Official Board of Inspection considers that existing tests are inadequate. The tests are classified in type tests only, type tests and routine productions…
Brown coals and lignites — Classification by types on the basis of total moisture content and tar yi...
Brown coals are classified in this International Standard according to the following properties: total moisture content calculated on the ash-free basis; tar hiels calculated on the dry, ash-free basis. In tables class numbers, group number and code numbers of brown coal types are given.
1. SCOPE
1.1 This Standard covers recommended sizes and other dimensional data for
various kinds of wire nails, spikes and staples commonly used in the building
and packaging trades, and general statements on material finishes and coatings.
Measurement of the average viscometric degree of polymerization of new and aged electrical papers
Describes a standard method for determining the average viscometric degree of polymerization of new or aged electrical papers. The determination is made by measuring the intrinsic viscosity of a solution of the paper in an appropriate solvent.
Methods of measurement for equipment used in terrestrial radio-relay systems - Part 1: Measurements ...
Gives standard conditions of measurement and methods of measuring the characteristics common to sub-systems of terrestrial line-of-sight radio-relay systems and to simulated radio-relay systems using frequency modulation. The tests described are limited to analogue transmission systems. Standardizes the conditions and methods of measurement to be used to ascertain the performance of terrestrial…
Mechanical standardization of semiconductor devices. Part 3: General rules for the preparation of ou...
Gives general rules to be used for the preparation of outline drawings of integrated circuits and indicates how to number integrated circuit case leads.
Low-voltage fuses Part 4: Supplementary requirements for fuse-links for the protection of semiconduc...
For application in equipment containing semiconductor devices for circuits up to 1000 V a.c. to circuits of nominal voltages up to 1500 V d.c.
Establishes characteristics of semiconductor fuse-links in such a way that they can be replaced by other fuse-links having the same characteristics provided their dimensions are identical. Defines standard conditions for operation in service,…
Standard test procedures for photomultiplier tubes for scintillation counting
Establishes test procedures for photomultipliers for scintillation and Cerenkov detectors covering pulse amplitude characteristics, spurious pulse characteristics and pulse timing characteristics. This publication includes also a comprehensive discussion of applicable light sources: light-emitting diodes, spark light sources. Cerenkov sources, scintillator light sources and mode-locked lasers.
Gives requirements and characteristics to specify a hydrophone which is suitable as an IEC Standard Hydrophone for calibration purposes, to be used as a laboratory standard for comparison with other hydrophones intended for daily use.
