Safety requirements for electrical equipment for measurement, control
and laboratory use - Part 1:General requirements
Type test/ Routine test
Main test points A Between the following sections of class-I devices requiring grounding
1. Accessible conducting parts
2. Protective shielding
3. Metal barriers
B Protective conductor terminal or protective grounding pin
Test current If the rating of the test circuit is 16 A or less, 1.5 times
the test circuit rating. If the rating of the test circuit is more than 16 A, 2 times
the test cirsuit rating.
Allowable resistance value 0.1

or less See Remarks.
Test time 60 sec 2 minutes
Remarks • The test voltage must be 12 V or less.
• Calculate a resistance value from the voltage drop.
• In measurements of resistance, do not include the
value for the AC power cord's protective grounding
wire.
• The voltage drop in the protective bonding conductor
must not exceed 2.5 V.
• In measurements of resistance, do not include the
value for the AC power cord's protective grounding
wire.
Type test Routine test
Main test points A Between the following sections of class-I devices requiring grounding
1. Accessible conducting parts
2. Protective shielding
3. Metal barriers Between all accessible conducting
parts of class-I devices requiring
grounding
B Protective conductor terminal or protective grounding pin Grounding pin for an AC inlet or
power plug on the device side or pro-
tective grounding terminal of perma-
nently installed equipment
Test current 1. 25 Adc or 25 Aac (at the rated fre-
quency of the power supply) or
2. 2 times the rated device current,
whichever is greater.
For permanently installed equip-
ment, a current twice that of the
overcurrent prevention means speci-
fied by the installation manual. Not specified
Allowable resistance value 0.1

or less See Remarks. See Remarks.
Test time 1 minute 1 minute Not specified
Remarks In measurements of resistance, do
not include the value for the AC
power cord's protective grounding
wire. The voltage drop should not exceed
10 Vd or 10 Vac. Continuity should be detected during
earth continuity testing.
