ISO/TR 17671-4 gives general guidance for the satisfactory design, production and control of welding and details the possible detrimental effects which may occur, together with advice on methods by which they may be avoided. Generally it is applicable to all types of aluminium materials and is appropriate regardless of the type of fabrication involved, although the application standard/contract…

This International Standard specifies performance and testing requirements for the gas inflation systems for inflatable life-saving appliances complying with the requirements of the 1974 Safety of Life at Sea Convention (SOLAS 74), as amended, and IMO Resolution MSC.48(66). For the purposes of this International Standard, the gas inflation system consists of inflation gas, cylinder valve,…

Applies to all types of high-voltage current-limiting fuses designed for use outdoors or indoors on alternating current systems of 50 Hz and 60 Hz and of rated voltages exceeding 1 000 V. Some fuses are provided with fuse-links equipped with an indicating device or a striker. These fuses come within the scope of this standard, but the correct operation of the striker in combination with the…

Provides a common formal model for the IEC 61360-1 and ISO 13584-42 and facilitates their harmonization. Allows for the implementation of dictionary systems dealing with data delivered according to either of those standards.Provides a formal model for data according to the scope as given in the publications cited above, and thus provides a means for the computer-sensible representation and…

Is divided into three sections, each dealing with specific examples of standardized dimensions. Section I: Fuse-links having bolted connections: Type A, Type B, Type C. Section II: Fuse-links with flush end connections: Type A, Type B. Section III: Fuse-links with cylindrical contact caps: Type A. This standard covers dimensional systems but does not standardize characteristics.
