Manufacture Supervision

  • 01 Supervision basis

    Refer to the former Ministry of Power Industry, Ministry of Machinery Industry issued by the electricity Office (1995) No. 37 "Interim Provisions for the quality supervision of large power equipment", "General representative group working Regulations in large power equipment manufacturers".

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

    GB/T 50319-2013 "Construction engineering supervision Code", 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 the documents, letters, correspondence and so on, which have legal effect.

    The product equipment drawing confirmed by the user and the manufacturer and the modification notice issued by the design unit.

    Technical documents and design drawings related to national standards, industry standards, enterprise standards (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 reference standard, the requirements in the standard shall prevail in principle, except for the special requirements of the 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 buyer's supervision representative.

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

    Point W: The inspection or test project attended by the representative of the buyer's supervision, that is, the on-site witness.

    H point: When the supplier stops to wait for the inspection or test of the buyer's supervision representative, that is, the project is stopped for inspection.

    Upon receipt of the witness notice, the Demander shall promptly send a representative to the site of the supplier's inspection or test to participate in on-site witness or stop work for inspection. If the representative of the Demander cannot attend on time, point W can be automatically converted to point R, but if point H is not agreed to be converted to point R by written notice of the Demander, 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 suppliers to cooperate with supervision

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

    3.2 The Supplier shall provide the demander's supervision representative with the convenience of work and life.

    3.3 The supplier shall inform the Buyer's representative of the equipment supervision project and time before witnessing the site or stopping work for inspection.

    3.4 Demander's supervision representative has the right to check (borrow) the technical information related to the contract supervision equipment. If Demander considers it necessary to copy and file, the supplier shall provide convenience.

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