Procedures
Procedures for type and sample tests.
Insulator for type tests:
The quantity of insulators to be tested for each test, as indicated in the cross-reference table in the relevant section (6,7,8.or 9), shall be taken from a lot of insulators which meets the requirements of the relevant sample and routine tests.
Sampling rules and procedures for sample tests
For the sample tests, two samples are used, E1 and E2. The sizes of these samples are indicated in the table below. When more thank 10,000 insulators are concerned they shall be divided into an optimum number of equal lots comprising between 2000 and 10000 insulators, The results of the tests shall be evaluated separately for each lot.

The insulators shall be selected at random from the lot. The purchaser has the right to make
The selection.
The samples shall be subjected to the applicable sample tests shown in the cross-reference table given in the relevant section (6,7,8 or 9), in the case of failure of the sample to satisfy a test, the relevant re-test procedure ( see subclause 8.3) shall be applied.
