Connectors for electronic equipment - Product requirements - Part 3-118: Rectangular connectors - De...
IEC 61076-3-118:2010 establishes specifications and test requirements for a connector with four contacts plus PE contact, for use in industrial environments. This standard also specifies free and fixed connectors, with round contacts, suitable for screw or crimp terminations. Other terminations techniques, as solder or printed board connections are upon agreement between manufacturer and user.…
Guidance for evaluating exposure from multiple electromagnetic sources
IEC/TR 62630:2010(E) describes exposure evaluation concepts and techniques for the overall exposure level in spatial regions and occupants caused by the simultaneous exposure to multiple narrowband electromagnetic (EM) sources. Throughout this Technical Report, it is assumed that the exposure evaluation occurs under static conditions, i.e., the source position and transmit-mode characteristics (e…
Binders for paints and varnishes — Gum rosin — Gas-chromatographic analysis
ISO 19334:2010 specifies a gas-chromatographic method for determining the amounts of certain rosin acids in gum rosin using capillary gas-chromatographic separation of the volatile methyl esters of these acids. It is intended primarily to permit the identification of gum rosin from specific species of pine trees. It is not designed for the quantitative analysis of gum rosin. If such analyses are…
