In our ordinary life, the use of wires and cables is becoming more and more extensive. The following is the relevant knowledge introduced to you - what is the on-site acceptance standard for wires and cables?

A. Acceptance basis:

a. Code for acceptance of construction quality of building electrical engineering;

b. Material standard table;

c. Accept the original sample;

B. Acceptance tools: steel tape and vernier caliper;

C. Time of arrival acceptance: inspection of incoming merchandise;

D. Sampling inspection proportion: for the incoming batch, the same specification and model shall not be less than 3 volumes;

E. Acceptance steps:

a.Data inspection: the mobilized products must have the product quality inspection report issued by the national accreditation institution and the original product certificate; If there is no inspection report and product certificate, the material will be rejected.

a. External packaging inspection: the packaging is complete, and the product brand, specification and model on the packaging shall be consistent with the requirements of the order;
