Those tests underlined below involve very important working characteristics. The editor of the specification shall pay special attention to the selection of those test items into the detailed specification. For the convenience of the writer of the specification, the following test items are listed in the form of a brief table, and the test items should be selected according to the specific application of the part. ③ Exceeding the requirements of the specification may incur economic costs, but the writer of the specification may specify test items and sampling levels that are less than or equal to the values ​​in the blank detailed specification.
General requirements
3.1.1 If additional type tests not specified or referenced in IEC 1007 are required, these tests shall be fully specified in the detail specification.
3.1.2 Any destructive test in the test schedule shall be indicated by the symbol \D\. Inverse: The destructive test in the blank detailed specification does not use the "D\" mark. Approved by the State Administration of Technical Supervision on August 2, 1994 and implemented on March 1, 1995
GB/T15183-94
3.1.3 The test should be carried out in groups according to the sampling level required in the table. And when specified (see 4.1b), the test sequence required should be followed. When it is not required to test 100%, the inspection level and the quality level can be selected from IEC410. 3.1.4 The completed detailed specification should determine the component identification number and version status. Method:) The identification number is determined by the formulating unit (manufacturer or user) ) is determined within its own system. Therefore, this identification number is not subject to any external law or regulation. 2 In the specific case where the manufacturer intends to list its detailed specification as an item in the standard catalogue QC001004, the national representative body will specify and apply the number in its registration.
3.1.5 In addition, the component manufacturer shall specify a number for the detailed specification, which number includes this specification number, the manufacturer's identification code letter and its specific number in the registration system, for example GB/T15183/PQR/1234. NOTE: After the detailed specification has been assigned a standard abbreviation in accordance with the requirements of 3.1.5, the detailed specification becomes part of the contract order. Copies of all these detailed specifications shall be retained by the manufacturer's general inspector. 3.2 Ratings and characteristics
3.2.1 Ratings
In the case of detailed specifications drawn up by the user, the values ​​of the ratings of the components included in the detailed specification shall be agreed upon in advance between the user and the manufacturer. These ratings shall not exceed the manufacturer's approved capability (see 1.9 of GB/T 14860). 3.2.2 Characteristics
The user shall specify the spare characteristics required for the components in the detailed specification. 3.3 Outline drawings and winding diagrams
3.3.1 The detailed specification shall include an outline drawing of the transformer. Such drawings shall be able to show the important characteristics of the transformer, such as dimensions affecting interchangeability, restrictions on installation and marking requirements.
3.3.2 The detailed specification shall include a diagram showing all cable groups, screens, taps and phases, and providing terminal identification markings. 3.3.3 Where the transformer is required to be connected to a circuit supplying true current, full details of the circuit shall be given together with the load and component values. 4 Inspection requirements specified in the detailed specification
Conformity inspection
The detailed specification shall include the following instructions;
Sampling inspection shall be carried out at the normal inspection level of 1EC410. Unless otherwise specified (see 3.1.3), the tests in the sheet may be carried out in any order. h
Components which have been subjected to a destructive test (marked with D) shall not be released under the capability approval procedure specified in GB/T 14860. d.
The values ​​given for the test limits shall be absolute values: test errors shall be taken into account. 4.2 Design qualification
The tests specified in the design qualification are those which the specification writer considers to be unsuitable for batch release, but are suitable for qualification tests for new and original designs. Therefore, these tests are only carried out when specifically specified in the order, and this meaning shall be explained in the detailed specification.
If design qualification is required, the number of samples shall be specified in the detailed specification, and it shall be specified that no samples shall fail. Note: Unless otherwise specified, two samples shall be provided. 5 Detailed specification
The following blanks shall be filled in according to the requirements of Chapter 3, and the detailed specification shall constitute the relevant detailed specification. Note: The first and second detailed specifications shall be written according to the requirements of the user detailed specification. When the manufacturer needs to make a detailed specification, some necessary changes are required, but the basic format should be retained.
