Gives values of both plain end tubes for general purpose use and precision tubes. Its purpose is to give guidance on the selection of sizes for all activities concerned with the standardization of steel tubes, both nationally and internationally, to serve as a ready reckoner and to avoid the use by different countries of different masses for a tube of the same size. It is not applicable to tubes…

Standardizes test methods to determine the essential parameters and technical characteristics of electro-heat installations comprising industrial induction channel furnaces for melting, holding and super-heating.

Describes definitions for standard degrees of protection provided by enclosures; protection of machines against harmful effects due to the ingress of water; designation for these protective degrees, and tests to verify that the machines meet the requirements.

IEC 60994:1991 applies to any type of reaction or impulse turbine, as well as to any type of pump-turbine and storage pump, coupled to an electric generator or motor. It covers the field of vibration and pulsation tests referred to as standard tests. The contents of the corrigendum of April 1997 have been included in this copy.

S'applique à tout type de turbine à réaction ou à action, ainsi qu'à tout type de pompe-turbine et de pompe d'accumulation, couplée à un alternateur ou à un moteur. Couvre le domaine des essais de vibrations et de fluctuations qualifiés d'essais standards. Le contenu du corrigendum d'avril 1997 a été pris en considération dans cet exemplaire.

Applies to the quality testing of microimages produced with a given micrographic system and allows to determine the potential legibility of documents recorded with that system. Annex A gives optional features for ISO test chart No. 1. This second edition cancels and replaces the first editions (ISO 435:1975 and ISO 446:1975), which have been merged into a single International Standard.

Lays down interchangeability dimensions and tolerances in millimetres. Ball-lock punches are standardized in round, square, rectangular and oblong shapes, and dimension ranges are given for these shapes. It also gives materials and hardness as examples, and specifies the designation. The main use of punches defined in this standard is for punching holes in steel sheet. They may also be used for…

This second edition cancels and replaces the first edition (ISO 6802 :1982), clause 5 of which has been technically revised. The rubber and plastics hoses are frequently flexed in service. As there may be a need to take this into account during testing, ISO 6802 provides a standard method of flexing during impulse testing. Uses a standard cycle during impulse testing by the method of ISO 6803.…

Specifies the majority of tolerances on dimensions used by ISO/TC 5/SC 1 in drawing up International Standards concerning steel tubes. Is intended for use as a basic document by all ISO technical committees concerned with the standardization of steel tubes. It cannot, therefore, be used as a standard for the definiton of a product. This second edition cancels and replaces the first edition (1977…

1. Scope 1.1 General This Standard establishes limits and methods of measurement of the immunity of radio and television broadcasting receivers and certain associated equipment to degradation of performance due to electromagnetic disturbances. 1.2 Applicability This Standard is applicable to immunity of two classes of equipment from degradation of performance resulting from…
