The FM sound transmitter is connected to a test load with an impedance expressed in return-loss relative to the nominal load impedance of the transmitter of not less than 26 dB at frequencies within the FM broadcasting band and 16 dB at frequencies of any measured unwanted frequency outside this band

The coatings covered by BS EN 10310 are applicable to longitudinally or spirally welded steel tubes and to seamless steel tubes and their fittings components used for the construction of pipelines conveying liquids

BS EN 13245-1 covers the codification system for Data block 3 to 5

but is for use in conjunction with appearance or physical property tests to follow the accelerated exposure

Why should you use BS EN 62321-3-1 - Determining the levels of certain substances in electrotechnical products

Conservation of cultural heritage. Cleaning of porous inorganic materials. Laser cleaning techniques for cultural heritage Ingestion-build-100998 The FM sound transmitter is1 Scope This European standard applies to porous inorganic materials constituting cultural heritage. It provides the fundamental requirements of the laser parameters and guidelines for the choice of the laser operational parameters, in order to optimize the cleaning procedure.
