scope:

This International Standard specifies production tests and inspections, and marking requirements for positionindicating lights used in conjunction with various items of life-saving equipment, including survival craft interior lights. Specifically, it applies to position-indicating lights which have been type approved by or on behalf of a national maritime safety administration, to the requirements of the International Maritime Organization LSA Code, for use in ships subject to the requirements of the International Convention for the Safety of Life at Sea (SOLAS), 1974 (as amended). The basic principles may also be considered suitable for position-indicating lights manufactured to other than the IMO requirements.
