This International Standard specifies the tests conditions applied to all components, equipments and structures located in zones designated as "fire zones" and built to satisfy the minimum specified level for resistance to fire. Two grades of resistance to fire are applicable to components, equipments and structures. Annexes A and B give details of the types of burners providing the…

This International Standard specifies the dimensions and location of the image area produced by the camera aperture Type W on 16 mm motion-picture film intended for enlargement to non-anamorphic 35 mm motion-picture film with an image aspect ratio of 1,66:1 or greater. This International Standard also specifies the dimensions and location of the corresponding image area on a 35 mm internegative…

Prescribes terms and methods of test for positive step-function temperature coefficient thermistors, insulated and non-insulated types, typically made from ferro-electric semi-conductor materials. Establishes standard terms, inspection procedures and methods of test for use in detail specifications for Qualification Approval and for Quality Assessment Systems for electronic components.

This International Standard specifies the dimensions for fixing a bracelet to a wristwatch-case with the use of spring bars. This International Standard is applicable to wristwatch cases of two types and spring bars of three types.

Gives the requirements for one type of heat-shrinkable polyolefin sleeving with a temperature index of 135 and a nominal shrink ratio of 2:1. This sleeving is not flame retarded. It is normally supplied with internal diameter up to 102 mm and the standard colour is transparent.
