Gives the requirements for group 1 portable, transportable and fixed apparatus for detecting and measuring the methane concentrations in mine air. This apparatus, or parts of apparatus are meant for use in mines susceptible to firedamp. Applicable to apparatus meant for detecting and measuring the volume ratios of methane in air from a volume fraction of 0% up to 100%.

IEC 62271-100:2008 is applicable to a.c. circuit-breakers designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V. It is only applicable to three-pole circuit-breakers for use in three-phase systems and single-pole circuit-breakers for use in single-phase systems. This second edition cancels and replaces the first edition published in 2001 and its amendments 1 (2002) and 2 (2006). It also cancels and replaces IEC 61633 and IEC 62271-308. The main changes with respect to the previous edition are listed below:
- the introduction of harmonised (IEC and IEEE) TRV waveshapes for rated voltages of 100 kV and above (amendment 1 to the first edition);
- the introduction of cable and line systems with their associated TRVs for rated voltages below 100 kV (amendment 2 to the first edition);
- the inclusion of IEC 61633 and IEC 62271-308.
This standard shall be read in conjunction with IEC 62271-1, first edition, published in 2007.
