1.1 This standard covers methods of test for determining the following requirements of 14 mm nominal diameter sparking plugs used in the high tension spark ignition system of internal combustion engines, excluding aircraft engines:
a) Sparking under pressure,
b) Insulation resistance under heat,
c) Gas leakage under room temperature,
d) Gas leakage under heat,
e) Thermal shock strength of insulator,
f) Mechanical impact strength of insulator, and
g) Torque strength.
1.2 It does not cover dimensional requirements of sparking plugs, for which reference may be made to IS: 1063-1963.
