Where testing is required, the field
representative of the certification organization
or inspector of the inspection agency performing
the safety evaluation of the equipment may
accept reports or other evidence of testing from
a certification organization, a testing
organization, a professional engineer, or another
responsible qualified person.
Dielectric Testing
• For equipment rated 30 V or less, the test
voltage shall be 500 V ac. The dielectric
strength test may be made by applying a dc
voltage instead of an ac voltage, provided that
the voltage used is 1.414 times the values
Dielectric Testing
• For equipment rated above 600 V, the
dielectric voltage withstand test of a particular
equipment Standard used in the electrical
equipment or product evaluation shall apply.
Dielectric Testing
• The dielectric strength testing may be
performed on a sampling basis provided that
the electrical equipment or products are of
consistent quality with respect to factors such
as routing of conductors, dressing of wiring,
neatness, etc. (see FEPPM)
Determining Sample Size
For Dielectric Strength Testing
• Criteria for selecting a sampling basis is as follows:
– The samples shall be selected at random by the special
inspection representative.
– If any of the samples fail the dielectric strength test, 100%
of the lot or batch shall be subjected to the dielectric
strength tests.
– The sample sizes outlined in Table 1 are minimums and
may be increased up to 100% of the lot or batch size where
the construction and quality of work are not uniform or
are not adequate, or as otherwise instructed by the AHJ.
– The sample size tested shall be recorded.
Determining Sample Size
For Dielectric Strength Testing
The general inspection levels are classified as follows:
• General inspection level I applies to electrical equipment or
products that are manufactured using an automated or controlled
process where consistent quality is always expected. Electrical
equipment and products in this category contain little or no hand
• General inspection level II applies to electrical equipment or
products that contain a moderate amount of hand wiring.
• General inspection level III applies to electrical equipment or
products that contain a large amount of hand wiring. Electrical
equipment and products such as industrial control panels are
considered here.
Note: The general inspection levels are extracted from Table I of MIL-STD35
105E, and the sample size is selected from Table II-A of MIL-STD-105E.
Determining Sample Size
For Dielectric Strength Testing
Strain Relief Testing
• Strain Relief testing of power supply or
interconnecting cords is not required provided
that the strain relief mechanism meets the
following criteria:
– It is certified for the particular cord type; and
– It is suitable for the shape of opening and
application in that its dimensions correspond to
the size of the opening in which it is fitted, in
accordance with certification conditions.
