as the European directive 2008/47/EC concerning aerosol generators does not cover the essential functions of cartridges for liquefied petroleum gas

BS 13500 on code of practice for delivering effective governance of organizations is useful for:

Externally threaded fastener manufacturers

and a clock-driven drum that carries a chart on which the pen movement records against a temperature scale

BS EN 61000-4-5 defines:

Calibration of wavelength/optical frequency measurement instruments - Optical spectrum analyzers Ingestion-build-86103 as the European directive 2008/47/EC1 Scope This part of IEC 62129 specifies procedures for calibrating an optical spectrum analyzer that is developed for use in fibre optic communications and designed to measure the power distribution of an optical spectrum. It does not apply to an optical wavelength meter that measures only centre wavelengths, a Fabry Perot interferometer or a monochromator that has no display unit.
