ISO Guide 33:2015 describes good practice in using reference materials (RMs), and certified reference materials (CRMs) in particular, in measurement processes. These uses include the assessment of precision and trueness of measurement methods, quality control, assigning values to materials, calibration, and the establishment of conventional scales. This Guide also relates key characteristics of…

1.1 This Standard applies to surge protective device (SPD) components designed to mitigate the effects of transient overvoltages and surge events when used on electrical distribution systems rated at not more than 750 volts. 1.2 SPD Components containing integral thermal devices are within the scope of this Standard. 1.3 Components include but are not limited to metal oxide varistors (MOVs),…

1 Scope This International Standard deals with the safety of electric motor-operated or magnetically driven: – HAND-HELD TOOLS (IEC 62841-2); – TRANSPORTABLE TOOLS (IEC 62841-3); – LAWN AND GARDEN MACHINERY (IEC 62841-4).
