This Standard specifies performance requirements for magnetic ballasts for discharge
lamps such as high-pressure mercury vapour lamps specified in JIS C 7604, low-pres-
sure sodium vapour lamps specified in JIS C 7610, high-pressure sodium vapour lamps
specified in JIS C 7621 and metal halide lamps specified in JIS C 7623, for use on
a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, having the rated secondary voltage up to 1 000 V to be used in general locations (hereafter referred to as "ballasts").
Clauses 1 through 11 specify general requirements of ballasts, and clauses 12
through 15 each detail specific requirements for a particular type of ballast.
It applies to complete ballasts and their component parts such as reactors, trans-
formers and capacitors.
This Standard specifies the requirements for a type test--it does not include the
requirements for the tests of individual ballasts performed during manufacture.
NOTE 1 For certain types of discharge lamps an ignitor is required.
NOTE 2 Extension of the standard to cover ballasts incorporating, or for use with,
series capacitors is under consideration.
NOTE 3 The performance requirements of ballasts for tubular fluorescent lamps
are covered by JIS C 8118.
NOTE 4 There are regional standards regarding the regulation of mains current
harmonics for end-products such as tuminaires and independent con-
trol gear. In a luminaire the control gear is dominant in this respect.
Control gear, together with other components, should comply with these
standards.
NOTE 5 The International Standard corresponding to this Standard and the sym-
bol of degree of correspondence are as follows.
