1. Scope 1.1 This test method is applicable to materials employed in light diffusers and lenses. 1.2 It is the intent that tests made in conformity with this test method will develop data to enable regulatory bodies to determine the acceptibility of such material when employed in locations where performance in terms of "falling from an installed position before igniting" is…

Applies to directly heated positive temperature coefficient thermistors, insulated or non-insulated, having a resistance temperature characteristic which approximates to a step-function. Typically they are made of ferro-electric semi-conductive materials. Specifies the conditions for approval, acceptance and continuous quality control. Defines the terminology for the thermistors covered by this…

Applies to concrete vibrators, the active part (vibrator bottle) of which is intended to be immersed into the mass of concrete to be vibrated. Stationary concrete vibrators intended to vibrate concrete moulds, for example for prefabricated concrete elements, are not within the scope of this standard.

Describes methods of measuring the specified properties of materials generally referred to as ferrites for application at microwave frequencies and is a guide for the drafting of specifications for general use in ferrite technology. This standard should be read in conjunction with IEC 60392.

Applies to fixed resistors for use in electronic equipment. Establishes standard terms, inspection procedures and methods of test for use in specifications for qualification approval and for quality assessment systems for electronic components.

Applicable to fixed capacitors for use in electronic equipment. Establishes standard terms, inspection procedures and methods of test for use in sectional and detail specifications for qualification approval and for quality assessment systems.

Gives general information and methods of test common to all types of piezoelectric filters.
