47、se related to lithium batteries and light-emitting diode (LED) light sources, the growing practice of incorporating electronic circuits and the introduction of intrinsically safe caplights which can be certified without reference to performance requirements. It is intended that there should be a str
48、onger link between Part 1 (Construction) and Part 2 (Performance) of this Standard by upgrading the reference in the Scope from a note to a requirement. In addition, as this standard is now to become part of the IEC 60079 series, changes have been made to bring it more in line with others in the ser
49、ies by cross referencing. This has enabled a reduction in the number and length of clauses in the standard.
