1.1 General
This Standard addresses the geotechnical engineering aspects of
(a) gravity-base structures;
(b) fill structures;
(c) fill-retention structures; and
(d) pile-supported structures.
Specific considerations include site investigations, general design principles,
the influences of soil and natural processes on the foundation components, and
the geotechnical factors that…
Intrinsically Safe and Non-incendive Equipment for Use in Hazardous Locations
1. Scope
1.1
This Standard specifies tests for the testing of non-incendive electrical
equipment and the details of construction and tests for intrinsically safe
electrical equipment for use in the following hazardous locations in accordance
with the Rules of the Canadian Electrical Code, Part I, and CSA Standard

(b) Class II, Groups E…
Connectors for frequencies below 3 MHz for use with printed boards - Part 12: Detail specification f...
Covers dimensions, general requirements and tests for a range of sockets designed for use with integrated circuits in dual-in-line format. Sockets include standard type and low-profile type.
Plastics pipes and fittings — Opacity — Test method
The principle consists in measuring the light flux passing through a test piece cut from a pipe or fitting as a percentage of the incident light flux on the test piece. The standard lays down the maximum acceptable limit for the light which may pass through the wall of the pipe or fitting, if the product standard specifies that they shall be opaque.
Measurement microphones - Part 1: Specifications for laboratory standard microphones
Specifies mechanical dimensions and certain electroacoustic characteristics for condenser microphones used as laboratory standards for the realization of the unit of sound pressure. The specifications are intended to ensure that primary calibration by the reciprocity method can be readily carried out. Establishes a system for classifying laboratory standard condenser mocrophones.
Applies to electroheating installations comprising industrial coreless (crucible) induction furnaces for melting and for holding at temperature a molten charge. Standardizes test methods to determine the essential parameters and technical characteristics of electroheating installations comprising the furnaces indicated above.
Specifies system parameters and applies to the pre-recorded optical reflective disc system called 'compact disc video (CD video)' containing digital audio and 'Laser Vision' video information. In the case of CD video, this standard modifies the relevant text in IEC 60908.
