Supervision

01 Basis of supervision

Reference to the former Ministry of Electric Power Industry, Ministry of Machinery Industry issued by the Office (1995) No. 37 document "Interim Provisions on Quality Supervision of Large Electric Power Equipment" , "Regulations on the Work of the General Representative Group in Large Electrical Equipment Manufacturing Plants".

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

GB/T 50319-2013 "Specifications for Construction Project Supervision", GB/T 19000-2016/ISO 9000:2015 "Quality Management and Quality Assurance" Standard.

The relevant commercial 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 adopted by the technical documents and the design drawings are inconsistent with each other, the national standards, industry standards, and enterprise standards shall be adopted as the recurrence order.

When the design drawing is inconsistent with the referenced standard, the requirements in the standard shall prevail in principle, except for those with special requirements for parts.

02 Supervision method

Document witness, site witness and stoppage for inspection, namely R point, W point, H point.

Each time after the completion of the supervision content, the supplier and the supervision representative will perform the signature procedure on the witness form. The supplier shall deliver one copy to the demand's supervision representative.

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

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

H Point : The supplier stops work at this point to wait for inspection or testing by the demander's manufacturing supervision representative, that is, it 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 demander's representative cannot attend on time, point W can be automatically converted to point H, but if point h is converted to point r without the demander's written notice, the supplier will not transfer to the next process and agree with the demander to change the witness time.If the buyer is still unable to participate on time after the change, the H point will be automatically converted to R point.

03 Requirements for Supplier's Cooperation in Manufacturing Supervision

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

The supplier shall provide the demander's supervision representative with convenience in work and life.

The supplier shall inform the representative of the buyer of the equipment supervision project and time before on-site witness or stopping work for inspection.

The demander's supervision representative has the right to check (borrow) the technical data related to the contract supervision equipment. If the demander deems it necessary to copy and file, the supplier shall provide convenience.

After witnessing, the supplier shall provide relevant inspection, test records and report data to the manufacturing supervision representative of the demander.
