ISO 18278-2:2004 specifies a laboratory test procedure for the determination of the acceptable welding current range and the assessment of electrode life using a multi-spot test with specific conditions. ISO 18278-2:2004 is applicable for the assessment of the weldability of uncoated and coated sheet steels of thicknesses up to 3 mm. The test procedure specified in this International Standard and…

Scope 1.1.1 This Standard applies to ac and dc type portable fuel cell power systems, with a rated output voltage not exceeding 600 V, for commercial, industrial, and residential indoor and outdoor use in non-hazardous locations, in accordance with the Rules of the National Electric Code, ANSI/NFPA 70. 1.1.2 This Standard does not apply to portable fuel cell power systems that are a.…

ISO/TS 17892-12:2004 specifies methods of test for the determination of the Atterberg limits of a soil. The Atterberg limits comprise the liquid limit, plastic limit and shrinkage limit. These limits are also called consistency limits. This document covers the determination of the liquid limit and the plastic limit only. The liquid limit is the water content at which a soil changes from a liquid…

ISO/IEC 23290:2004 specifies functions for using an H.323 packet network in order to interconnect two Private Integrated services Network eXchanges (PINXs) forming part of a Private Integrated Services Network (PISN). Interconnection is achieved by carrying the inter-PINX signalling protocol over the H.323 call signalling channel, making use of the protocol tunnelling facilities of H.323, and…
