1、 Basis for supervision

Refer to the "Interim Provisions on Quality Supervision of Large Electric Power Equipment" and "Working Regulations of the General Representative Group in Large Electric Power Equipment Manufacturing Plants" issued by the former Ministry of Electric Power Industry and the Ministry of Machinery Industry.

Refer to DL/T 586-2008 "Technical Guidelines for Equipment Manufacturing Supervision"

GB/T 50319-2013 "Code for Supervision of Construction Projects", GB/T 19000-2016/ISO 9000:2015 "Quality Management and Quality Assurance" standards.

Relevant business terms and technical agreements in the equipment purchase contract signed between the user and the manufacturer, including legally binding documents, letters, correspondence, etc.

Product equipment drawings confirmed by the user and the manufacturer and modification notice issued by the design unit.

National standards, industry standards, and enterprise standards involved in technical documents and design drawings (subject to the latest version). If the standards used in technical documents and design drawings are inconsistent with each other, national standards, industry standards, and enterprise standards will be used in the derivation order.

When the design drawings are inconsistent with the quoted standards, the requirements in the standards shall prevail in principle, except for those with special requirements for parts and components.

2、Method of construction

Document witness, on-site witness and shutdown pending inspection, namely R point, W point, H point

After each manufacturing supervision content is completed, the supplier and the manufacturing supervision representative will complete the signature procedures on the witness form. The supplier shall submit one copy to the demander's manufacturing supervision representative

Point R: The supplier only needs to provide inspection or test records or report items, that is, document witness

Point W: Inspection or test items attended by the buyer’s supervision representative, that is, on-site witness

Point H: The supplier stops work at this point to wait for inspection or testing by the demander's manufacturing supervision representative, that is, the supplier stops work pending inspection.

After receiving the witness notice, the demander shall promptly send representatives to the supplier's inspection or testing site to participate in on-site witnessing or stop work pending inspection. If the representative of the demand side cannot attend on time, point W can be automatically converted to point R. However, if point H does not receive written notification from the demand side and agrees to be converted to point R, the supplier will not move to the next process on its own and agree with the demand side to change the witness time. . If the buyer still cannot participate on time after the change, point H will be automatically converted to point R.

3、Requirements for suppliers to cooperate with manufacturing supervision

3.1The supplier has the obligation to cooperate with the demander's supervision and provide relevant information in a timely manner without incurring any costs.

3.2The supplier provides work and life convenience to the demand-side manufacturing supervision representatives

3.3The supplier shall notify the demander's manufacturing supervision representative of the equipment manufacturing supervision items and time before witnessing on-site or suspending work for inspection.

3.4The demander's manufacturing supervision representative has the right to check (borrow) technical data related to the contract manufacturing supervision equipment. If the demander considers that it is necessary to copy and archive it, the supplier should provide convenience.

     3.5The supplier shall provide the inspection and test records and reports to the supervision representative of the demander after  the witness.
