Environmental testing - Part 3-3: Guidance - Seismic test methods for equipments
IEC 60068-3-3:1991 Guidance is included in each of the three test methods referred to in this standard but it is specific to the test method. The guidance in this standard is directed towards choosing the appropriate test method and applying it to seismic testing.
Plain end steel tubes, welded and seamless — General tables of dimensions and masses per unit length
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.
Rotating electrical machines - Part 5: Classification of degrees of protection provided by enclosure...
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.
Guide for field measurement of vibrations and pulsations in hydraulic machines (turbines, storage pu...
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.
Guide pour la mesure in situ des vibrations et fluctuations sur machines hydrauliques (turbines, pom...
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.
Micrographics — ISO character and ISO test chart No. 1 — Description and use
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…
Rubber and plastics hose and hose assemblies with wire reinforcements — Hydraulic impulse test with ...
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.…
