Inspection and tests | 1) Type tests, which have been carried out by an independent testing laboratory on the similar products, shall be submitted with the tender as follows:
2) Routine tests, which shall be made by the manufacturer on each supplied individual product at the manufacturer's factory, shall be submitted to the Purchaser upon the goods to be delivered. These tests shall be carried out as follows:
3) Acceptance tests (sample test), which have been carried out by an independent testing laboratory on supplied typical voltage transformer, including:
|
1)We offer the similar type test report LCZ-35 ( because 35KV is stardared voltage in our country ,this voltage adapt below 35kv current transformer ) 2).when manufacturer finish the producing , manufacturer will offer for buyer 3).when manufacturer finish the producing , manufacturer will offer for buyer |
