This International Standard specifies production tests, inspections, conformity assessment procedures and marking requirements for life-saving appliances that utilize pyrotechnic devices in functioning. Specifically, it applies to products which have been evaluated and tested in accordance with the International Maritime Organization (IMO) Recommendation on testing of life-saving appliances, and type approved by maritime administrations to the requirements of the IMO Life-Saving Appliance (LSA) Code for use on ships subject to the requirements of the 1974 Safety of Life at Sea Convention (as amended). The basic principles may be considered suitable for pyrotechnic life-saving appliances manufactured to other than the IMO requirements, however this International Standard applies directly only to products for which it contains specific requirements. This International Standard does not affect the requirement in part 2, section 4 of the IMO Recommendation on testing of life-saving appliances to periodically repeat full prototype testing of pyrotechnic life-saving appliances. However, compliance with this International Standard may be taken into account by administrations in prescribing the frequency of such tests.
