Potassium hydroxide for industrial use — Method of assay
Method for determination of the titre, conventionally expressed as percentages by mass of KOH. There are three ways: a) total alkalinity, b) caustic alkalinity corresponding to the total alkalinity less the alkalinity due to carbonates and c) actual potassium hydroxide corresponding to the total alkalinity less the alkalinity due to carbonates and any hydroxide which may be present. The principle…
Heat-resisting equipment wires for aircraft — Methods of test
This International Standard specifies the rest procedures suitable for establishing the compliance of wires with the performance requirements stated in ISO 2032. They are intended for use as a basis for specifying tests in the relevant national specifications when the national type approving authorities consider that existing tests are inadequate. The test procedures are classified in type tests…
Applicable to all types of solid organic and inorganic cylindrical scintillators used in scintillation counting and spectrometry. Standard dimensions are given in order to facilitate interchangeability of unencapsulated scintillators and to facilitate intercomparisons of measurements made with encapsulated scintillators.
High-voltage alternating current switch-fuse combinations and fuse-circuit-breaker combinations
This standard applies to three-pole units for public and industrial distribution systems which are functional assemblies of switches including switch-disconnectors and current-limiting fuses and thus able to interrupt:
- any load current up to the rated breaking current of the switch;
- any over-current up to the rated short-circuit breaking current of the combination…
Methods for measuring the performance of electric dishwashers
States and defines the characteristics of importance for determining the performance of household electric dishwashers in order to inform the consumer and describes the standard
methods for measuring these characteristics.
Methods for measuring performance of electric toasters for household and similar purposes
States and defines the principal performance characteristics of electric toasters for household and similar purposes which are of interest to the user, and describes the standard methods for measuring these characteristics.
Report on synthetic testing of high-voltage alternating current circuit-breakers
Applies to a.c. circuit-breakers within the scope of IEC 56
(Clause 1). It provides the general rules for testing a.c. circuit-breakers, for making and breaking capacities over the range of test-duties described in Subclauses 6.102 to 6.111 of IEC 56, by synthetic methods. The purpose of this standard is to establish criteria for synthetic testing and for the proper evaluation of results. Such…
Characteristics of string insulator units of the long rod type
Prescribes specified values for the electrical and mechanical characteristics and for the principal dimensions of string insulator units of the long rod type with insulating parts of ceramic material intended for a.c. overhead lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. The smallest insulator unit standardized has a lighting impulse withstand voltage…
