BS EN 15193:2007 contains:

including routine inspection

NOTE 1 See Clause 4 for waste discharge temperature limits

BS EN IEC 61158-3-19 also provides you with migration paths from previously existing industrial communications protocols

This part of IEC 62471 provides requirements regarding photobiological safety of the optical radiation emitted by image projectors

This revision of BS 1427 contains updates to specific methods since the previous standard and provides guidance on the use of the much wider range of available commercial test-kits

and also deals with such points of component design and plant layout as are fundamental to the proper functioning of such equipment

BS 5204-1 provides two grades of accuracy for each type

— It also describes a reduced dataset recommended for equipment generating low acoustic output levels
