Applies to electromechanical air break contactors for household and similar purposes provided with main contacts intended to be connected to circuits the rated voltage of which does not exceed 440 V a.c. with rated operational currents less than or equal to 63 A for utilization category AC-7a and 32 A for utilization category AC-7b, and rated conditional short-circuit current less than or equal…

This Particular Standard refers to IEC 601-1 and specifies the requirements for safety. The field of application includes, but is not limited to perioperative use, adult critical care application, paediatric and neonatal applications, general determination of saturation on hospitalized and non-hospitalized patients. Annex A gives a rationale.

The two methods described are applicable to all known types of thermoplastics and cross-linked thermoplastics pipes at any temperature and to any practicable test medium. They were developed on the basis of test data from pipes of relatively small sizes. The pipe sizes to be tested are specified in the relevant product standard.

Describes the classes 0 to 3 of the OSI transport protocol, defined in ISO 8073 using the formal description technique LOTOS, which is defined in ISO 8807. Transport protocol class 4 and NMCS are not covered. In view of complexity and widespread use of OSI standards it is imperative to have precise and unambiguous definitions of these standards. Formal Description Techniques form an effective…

Specifies general rules for appropriate implementation of radiographic inspection and stresses the technical specifications to be defined for agreement on discontinuity acceptance criteria by this technique. Annex A gives an extract of ASTM Standard E 155-85 "Standard reference radiographs for inspection of aluminium and magnesium castings" (slightly modified), Annex B grades of…

IEC 60317-40:1992 specifies the requirements of glass-fibre braided, silicone varnish treated, bare or enamelled rectangular copper winding wire, temperature index 200. NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot be established. Consequently, a class based on the requirements for temperature index and heat shock temperature cannot…

Specifies procedures for the transmission of configuration and routeing information between network entities, the encoding of the protocol data units used for the transmission of the configuration and routeing information, procedures for the correct interpretation of protocol control information, and the functional requirements for implementations claiming conformance to this standard. Procedures…

Specifies the minimum requirements for two classes (non-oil-resistant cover and oil-resistant cover) and five types of rubber steam hoses and hose assemblies. Hoses complying with this standard are not suitable for use in the preparation of foodstuffs, e.g. by steam cooking, or for special service applications, e.g. as in pile drivers.
