1. SCOPE
1.1 This standard applies to metric squares used by carpenters in determining
angles when fabricating parts from wood or other materials. Squares in
accordance with this standard shall be graduated with the International System
of Measurement (SI) Units. This standard will eventually supersede Imperial
graduated carpenter's squares now covered by CGSB 39-GP-21.
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…
Methods for measuring the performance of electric household coffee makers
States and defines the principal performance characteristics for electric coffee makers, which are of interest to the user and describes the standard methods for measuring these characteristics.
Methods of measurement for radio equipment used in the mobile services - Part 4: Transmitters employ...
Covers the definitions, the conditions and the methods of measurement used to ascertain the performance of transmitters having audio-frequency bandwidths generally not exceeding 10 kHz for the transmission of voice and other types of signals, using single-sideband amplitude modulation with full, reduced or suppressed carrier. This standard is intended to be used in conjunction with IEC 489-1.
Printed boards - Part 4: Specification for single and double sided printed boards with plain holes
Defines the characteristics to be assessed, the test methods to be used and establishes uniform requirements for judging properties and dimensions of single and double sided printed boards with plain holes. This standard is intended as a basis on which agreements between purchaser and vendor can be made.
Printed boards. Part 6: Specification for multilayer printed boards.
Defines the characteristics to be assessed, the test methods to be
used and establishes uniform requirements for judging properties
and dimensions of multilayer printed boards. This standard is
intended as a basis on which agreements between purchaser and
vendor can be made.
Fixed capacitors for use in electronic equipment - Part 13: Sectional specification: Fixed polypropy...
This publication also bears the number QC 301800, which is the specification number in the IEC Quality Assessment System for Electronic Components (IECQ).
Relates to fixed direct-current capacitors, using as dielectric a polypropylene film and electrodes of thin metal foils. Capacitors for reactive power exceeding 500 var are not covered by this standard. Prescribes preferred ratings and…
