Limitation of ballast heating test as per; clause no. 9.12 of IS 6616 of
1982. The tolerance of 1-degree C in the temperature rise will be
considered to compensate for reading error.
4.1. 5 The lumens per watt. Lumen output of the reference lamp is
measured using reference ballast and ballast under test by applying
rated voltage. Lumen/watt will be calculated for reference ballast and
sample ballast by dividing the lumen output of reference lamp by
total input wattage (lamp watts + ballast watts) in each case. The
sample ballast should not give lumen per watt less than 95% with
that of reference ballast.
4.1.6
Ballast loss (refer 1.0). Ballast loss should not be more than that
given in clause 1.0 (Table 1) of this specification.

Only one sample will be tested. If the tender sample fails in any test
given under 4.0, the sample will be considered as failed.

Lot:
The lot shall considered to be failed if more than one sample fails in
single requirement
or more than two sample fail in different
requirements given under clause 4.0.

Guarantee:
If the ballast fails within 18 months from the date of
acceptance, the failed ballast should be replaced free of cost by the
tenderer.
