Test

The product shall be inspected by the manufacturer before leaving the factory, and the product quality inspection certificate shall be attached to each outgoing package. The sampling quantity of each batch shall be at least 1 sample according to the delivery batch, which may also be stipulated by agreement between the supply and demand parties. If the results of the sample inspection items are unqualified, the sample should be doubled for the second test of the unqualified items, and the whole batch of products should be tested one by one.

The appearance of the product should be examined batch by batch under normal vision. Cable inspection is divided into type test, routine test and sampling test.

01 Type Test (T)

Including: structural size, insulation physical and mechanical properties, sheath physical and mechanical properties, electrical properties (conductor resistance (20℃)), voltage test, insulation resistance test, working capacitance, capacitor unbalance, shielding inhibition factor, combustion performance, identification, delivery length), combustion performance (if any), identification, delivery length.

02 Routine Test (R)

Including: structure size, insulation physical and mechanical properties, sheath physical and mechanical properties, electrical properties (conductor resistance (20℃)), marking, delivery length.

03 Sampling Test (S)

Including: identification, delivery length.

Product performance requirements and test methods in accordance with standard TICW/06-2009.

Check and accept

01

Each cable should be accompanied by product quality acceptance certificate and factory test report.The cable qualification certificate should indicate the start-up sequence number and insulation extrusion sequence number of the insulation extruder used to produce the cable.

02

Field inspection. When the contract goods arrive at the delivery place,upon receipt of notification from the buyer, the seller shall promptly go to the delivery location and organize an inspection with the buyer on the model, specifications, appearance, quantity, accompanying technical documents, packaging, etc. of the contracted goods based on the waybill and packing list. The buyer shall notify the seller of the date of Field inspection 3 working days in advance, and provide convenience for the seller's inspection personnel to work and live. The cost shall be borne by the seller. If the seller does not send a representative to attend, the buyer's inspection results shall prevail; If the seller's personnel fail to arrive at the site on time during the inspection, the buyer has the right to conduct the inspection on their own, and the inspection results and records are equally valid for both parties.

03

During Field inspection, if the contract goods are damaged, defective, short, or do not meet the quality standards and specifications stipulated in the contract due to the seller's reasons, the seller shall complete the equipment repair, replacement, or additional supply work as soon as possible without affecting the project progress. All expenses and responsibilities for delayed construction period arising from this shall be borne by the seller. If any damage, defect or shortage of the contracted goods is found due to the buyer's reasons, the seller shall repair, replace or supplement the corresponding parts as soon as possible after receiving the buyer's notice, and the buyer shall be responsible for the cost and delay in the construction period.

04

Sampling inspection. Before the shipment of cables (or after each batch of cables arrives), the buyer has the right to conduct sampling work. The buyer or a third party commissioned by the buyer shall take samples of the contract goods and send them to an authoritative inspection agency for inspection. If the sampled contract goods do not meet the requirements of the contract, the buyer has the right to expand the scope of sampling according to the contract, and based on the testing results and relevant provisions of the contract, require the seller to take measures such as re production, repair, etc Remedial measures such as replacement shall be taken until the inspection is qualified or the contract is unilaterally terminated. All related expenses incurred during this period shall be borne by the seller, and corresponding penalties shall be imposed according to the contract.

Supervision

01 Basis of supervision(T)

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.
