QUALITY STANDARD

SAMPLING METHOD
We use the recognized international quality control standards to conduct inspections. We refer to the most widely accepted sampling methods.

They are based on mathematical theories of probability and offer the advantage of clearly defining the number of samples to be drawn for inspection from a given lot or consignment. They also suggest the maximum number of defective items allowed in the sample size.

Unless otherwise instructed, Mixed Creations Co., LTD uses the Single Sampling Plan Normal Level II (according to the MIL-STD 105E standard). This is generally the common requirement for products manufactured in China.



Acceptable Quality Level (AQL)
As MIL-STD-105E is based on random sampling, therefore a few defectives are considered acceptable. The AQL is the maximum percent defective that, for purposes of sampling inspection, can be considered satisfactory as a process average. Different AQLs may be designated for different defects such as critical, major and minor defects. The AQLs should be agreed upon between buyer and supplier before the start of production.
The following AQLs are usually applied by us unless otherwise instructed by the client:

Remarks:
Acceptable quality level (AQL) sample inspection methods have been proven to be accurate over a long run. However, the quality level of merchandise at destination is generally lower than the per-shipment inspection results. This may be due to transport, handling, change in environment an/or reliability problems. Buyers are therefore advised to take this into consideration when deciding the AQL level.

Defect Classification
The customer defines the AQL and the maximum number of defective goods allowed in the sample size.  Defects detected during visual inspection are classified within 3 categories: "Critical", "Major" and "Minor"
　

• Critical: Likely to result in unsafe condition of contravene mandatory regulation       (no critical defect is accepted)

• Major: Reduce the performance of the product or is an obvious appearance defect

• Minor: Does not reduce the performance of the product, but is a defect beyond the defined quality standard.
