Appearance and Acceptance Rules
\t
The surface of magnetic core should be clean, with even color and be smooth. Noobvious loose is allowed. Grinding surfaces should be flat.
\t
For drop pieces of the core, on the mating surfaces, the size of drop pieces should not exceed 0.4% of the surface radius. While not on the mating surfaces, the size of drop pieces should not exceed 0.15% of the surface radius. The depths should not exceed 1 mm and utmost two drops are allowed.
\t
In principle, the cores should not have cracks, but if the cracks do not affect the product's mechanical strength and electromagnetic properties, they can be allowed. While the width of crack must not exceed 0.1mm and length should not exceed one-fifth of the maximum radius in either direction, the amount not more than 2. Check with visual observation (or compare with samples) and calipers with precision of 0.02mm.
\t
Foam or blister packaging is used in inner package, and for the outer package, cardboard box sealed with tape should be used.
\t
Product acceptance rules are based on the single sampling plan of GB2828《Sampling Procedures and Tables for Lot-by-Lot Inspection by Attributes》, For electromagnetic performance, special inspection level is S-3 and the AQL(Acceptable Quality Level) is 0.65; Other items needs accordance with the General Inspection level II with acceptable quality level AQL of 1.5.
\t
Customers should finish the acceptance inspection within three days after receiving the products, and inform suppliers the inspection results in writing; Otherwise acceptance is deemed.
\t
The data changes in this table should be confirmed by both parties.
