1. Scope 1.1 This Standard specifies energy efficiencies for liquid-filled distribution transformers. The Total Ownership Cost(TOC) methodology is recommended as the means for achieving these energy efficiencies, particularly for use by electric utilities. This Standard also specifies an optimal method for nonutility users, based on a modified TOC methodology that meets the conditions of energy…

1. Scope 1.1 This Standard specifies energy efficiencies for dry-type transformers. The Total Ownership Cost (TOC) methodology is recommended as the means for achieving these energy efficiencies, particularly for use by electric utilities. This Standard also specifies an optimal method for nonutility users, based on a modified TOC methodology that meets the conditions of energy cost. Note…

1.1 SCOPE 1.1.1 This standard applies to portable type gas camp lights for use: (a) With propane, butane, liquefied petroleum gas and any combination thereof; and (b) Outdoors only. 1.1.2 Lights and components employing materials or having forms of construction differing from those detailed in these provisions may be examined and tested according to the intent of the provisions…

La présente partie de l'ISO 8178 spécifie un format standard de rapport de mesure et d'essai pour consigner le résultat des mesurages des émissions des gaz d'échappement des moteurs alternatifs à combustion interne utilisés dans les installations mobiles, transportables et fixes, à l'exclusion des moteurs de véhicules conçus à l'origine pour des applications routières. La…

This part of IEC 61347 specifies particular safety requirements for ballasts for discharge lamps such as high-pressure mercury vapour, low-pressure sodium vapour, high-pressure sodium vapour and metal halide lamps. The standard covers inductive-type ballasts for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, associated with discharge lamps, having rated wattages, dimensions and…

This part of IEC 61347 specifies general and safety requirements for lamp controlgear for use on d.c. supplies up to 250 V and/or a.c. supplies up to 1 000 V at 50 Hz or 60 Hz. This standard also covers lamp controlgear for lamps which are not yet standardized. Tests dealt with in this standard are type tests. Requirements for testing individual lamp controlgear during production are not included…

This part of IEC 61347 specifies safety requirements for ballasts, excluding resistance types, for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, associated with fluorescent lamps with or without pre-heated cathodes operated with or without a starter or starting device and having rated wattages, dimensions and characteristics as specified in IEC 60081 and 60901. This first edition of IEC…

IEC 60332-3-21:2000 Specifies method of test for the assessment of vertical flame spread of vertically-mounted bunched wires or cables, electrical or optical, under defined conditions. The test is intended for type approval testing. The requirements for the selection of cables for testing are given. The flame spread is measured as the extent of damage of the cable sample. This procedure may be…
