It is a generic specification for semiconductor devices, discrete devices and integrated circuits, including multichip integrated circuits, but excluding hybrid circuits. It defines general procedures for quality assessment to be used in the IECQ System and gives general rules for measuring methods of electrical characteristics, climatic and mechanical tests, and endurance tests.

This National Standard of Canada is equivalent to American National Standards Institute standard ANSI T1.603-1990. In this standard, the minimal set of bearer services for the primary rate interface for the integrated services digital network (ISDN) that conforms closely to the architectural concepts described by CCITt are defined. The telecommunications environment in the United States…

This National Standard of Canada is equivalent to American National Standards Institute standard ANSI T1.604-1990. In this standard, the minimal set of bearer services for the basic rate interface for the integrated services digital network (ISDN) that conforms closely to the architectural concepts described by CCITt are defined. The telecommunications environment in the United States for…

1. Scope 1.1 This Standard defines the requirements for performance, installation and application, and performance verification of mechanical ventilation systems. This Standard applies to systems that are capable of providing minimum controlled rates of ventilation air to the habitable spaces of those single-family dwellings that (a) fall within the Scope of Part 9 of the National…

This technical report provides details of the test procedure to be employed for measurement of the density of smoke emitted from cables burning under defined conditions. lt describes the means of preparing and assembling test cables having an overall diameter from 10 mm upwards, the method of burning the cables, and gives the requirements for evaluating test results. Has the status of a…

In order to size mass-produced clothes, the body size of the intended wearer has to be defined and identified with the nearest size on a table of standard sizes. The processing of body measurement data as described in ISO/TR 10652 results in the grouping of body sizes. The sizing systems presented in annexes A to C are exemplary only. This Technical Report establishes a body sizing system to be…

Covers instruments designed primarily for the measurement of modulus of acoustic impedance/ admittance in the human external acoustic meatus using a probe tone of 226 Hz. Defines the characteristics to be specified by the manufacturer, lays down performance specifications for four types of instrument and specifies the facilities to be provided on three of these types. Methods of test to be used…

Defines the electrical and mechanical characteristics of FM audio recording which will provide for the interchangeability of recorded cassettes using the VHS system defined in IEC 60774. Applies to 525 line - 60 field and 625 line 50 field systems.

Defines a method for determination of the position of driver hand-controls in vehicles and for verification that the controls lie within the hand-reach envelopes. Applies for checking purposes in road vehicles using the actual dimensions of the vehicle. It refers directly to left-hand drive motor vehicles. Application to right-hand drive vehicles is assumed to be symmetrically opposite. The hand-…

This second edition cancels and replaces the first edition (ISO 5182:1978). Specifies the characteristics of the materials which are used for carrying current and transmitting force to the work. Gives normative references. Defines the term softening temperature. Classifies copper and copper alloys and sintered materials. Specifies test methods, designation, typical applications (annex A),…
