These tests are carried out on each
and every machines manufactured in the industry.
|
This tests are carried out on few
machines from the lot of the machines of same designs and specification. The
test result of the few tested machines are treated same, for the complete lot
of the machines.

It is conducted on each product
manufactured to confirmed proper manufacturing of each and every units. This
test is essential to be performed on each unit before distaching the products
to site.
|
It is conducted on first prototype of
product to confirm the design specification. This test is not repeated on
other products of same type. E.g. temp rise test.

This tests are intended to check the quality of
the individual test unit. This tests are done to insure the reliability of
test objects and consistency of the material use in their manufacture
|
This test are intended to proof or check
the design features .Type tests are done on samples when new design or design
changes are introduced.
