Statistical Inspection Procedure
Statistical Inspection Procedure
In addition to the inspection procedures that take place during your production processes, Suppliers and Agents are expected to carry out an independent Statistical Quality Control Inspection on all completed and finished garment deliveries prior to their dispatch.
This inspection should be in accordance with the criteria of BS6001:1991 Sampling Procedures and Tables for Inspection by Attributes, Instruction for its use are shown below together with the sampling table.
The inspection should take place at an acceptable quality level (AQL) of 2.5% for major faults and 4.0% for minor faults.
No critical faults are allowed – These garments should not be delivered without reference to the Buying Team.
The first column shows the Delivery Batch or Ordered Quantity. The second column shows the quantity of garments to be Inspected from that quantity i.e. the sample size. The samples must be selected at random from the delivery and must cover all sizes and colours in the order.
The third column of the table headed ‘2.5%’ gives the maximum number of MAJOR faults allowed in a sample size.
The column headed ‘4.0%’ gives the maximum number of MINOR faults.
If the number of faults found exceeds the acceptable level then the entire delivery will require a 100% inspection.
Garments must be inspected against:
Your copy of the approved Black Seal sample.
Specifications, information and other documentation that will have been provided for that style during the approval process.
Inspection reports made by your QC team during the production of the style.
The standards specified in the Supplier Manual for all other materials and trims.
Any Faults found must be classified as:
Critical faults – defined as dangers or safety problems which may cause injury or faults which contravene current legislation.
Major faults – defined as faults likely to cause the product to breakdown, to be marked down at point of sale or to result in customer complaints and/or customer returns.
Minor faults – defined as technical faults which would not result in customer complaints or returns but may cause a customer to select another garment.
Fault classification tables have been included at the end of this section. The tables are intended as a guide and are not exhaustive. If there are any queries regarding the classification of a fault Viyella should be contacted.
At the end of your inspection, the AQL Inspection Report form must be completed verifying that the delivery has met the required standards. A copy of the report must be forwarded to the Buying Office and a copy forwarded to the Distribution Centre with the delivery.
