This Appendix prescribes the minimum performance standards (MPS) for aircraft handheld fire extinguishers. As referred to in SAE AS6271, the applicable standard is ANSI/UL 2129 ‘Halocarbon Clean Agent Hand-Held Fire Extinguisher’, issued in February 2005. EASA has revised it as follows:
1. On page 9, replace paragraph 6.8 with the following:
‘An extinguisher shall operate as intended at temperatures from -40°C to 49°C as required per UL2129. Ground survival temperature of the unit shall be -54°C up to 85°C (refer to EUROCAE ED-14/RTCA document DO-160 revisions defined in CS-ETSO, Subpart A, paragraph 2.1, ground survival temperature).’
2. On page 12, replace the first phrase of paragraph 12.4 with the following:
‘The maximum indicated gauge pressure shall be between 150 and 250 % of the indicated charging pressure specified by the manufacturer (at either 20° or 21°C).’
3. On page 12, replace paragraph 12.5 with the following:
‘The mark used to indicate the charging pressure at the charging temperature (at either 20°C or at 21°C) as specified by the manufacturer shall be a minimum of 0.6-mm wide and not more than 1.0-mm wide.’
4. On page 12, disregard paragraphs 12.6 and 12.7.
