Final Random Inspection Techniques
About Final Random Inspection Techniques
Protocol (Customized QE checklist) for each inspection is prepared based upon contract specifications, customer/ regulatory / safety requirements, and product category before a day of Inspection date.
The Final Random Inspection covers the aspects below:
- Customer special checkpoints
- Quantity verification against PO/ Packing List
- Product descriptions check
- Workmanship (Visual Inspection)
- Measurement and weight
- Labelling and Inner packing
- Packing and Packaging
- On-site test which includes Functionality / safety/ Regulatory etc.,
Quantity check :
The Quality Engineer counts and then determines the number of cartons in the batch without removing them from the storage area by comparing with PO / Packing lists. Further selects generally few cartons as per procedure (square root of total cartons) & count the number of pieces on them one by one. This method provides a good confidence to buyers on related to quantity ordered is present & will be arrived to them.
Product Description check :
Verifying the style, color, appearance & feel of the product against the approved sample and technical specifications. Quality Engineer carefully compares them for each parameter well & provides the photos for reference. Any mismatches will be highlighted to take further actions / decisions by buyers.
Workmanship Check :
The products are randomly pulled as per the sample size, the Quality Engineer will check the products visually against customer approved sample or contract specification and all non-conformities are recorded based on below category of defects.
• Critical defect: Defects that render the product unsafe or hazardous for the end user or that contravene mandatory regulations.
• Major Defect: Defects can result in the product's failure, reducing its marketability, usability or sale ability.
• Minor Defect: Defects that do not affect the product's marketability or usability but represent workmanship defects that make the product fall short of defined quality standards.
The Standard ISO2859-1, ANSI/ ASQ Z1.4-2008 (Equivalent to MIL-STD-105 E) is followed for sampling plans. You can refer to the AQL Sampling plan table from below link
Size of the sample and unbiased representative selection of the sample is a vital part of the inspection process. Internationally most widely used accepted sampling plan is single sampling plan, inspection general level II. However, the customers are free to choose any other sampling plan as they feel appropriate.
Acceptable Quality Level :
Generally, for the workmanship check, internationally most widely followed AQL - Accept or Reject criteria for consumer goods is critical 0.0, Major 2.5 and Minor 4.0 defectives for consumer goods. However, the customers are free to choose any other AQL depending upon the product category, as they feel appropriate.
Measurement and weight :
Product measurements & weights from randomly selected pieces are checked against the specified requirements provided on the technical sheets. A detailed finding, discrepancies are highlighted in the report for easy reference.
Labelling and Inner packing :
The details like Material composition, Wash care, Barcodes, Warning Stickers, Hangtags, Country of origin, Inserts, Polybag / Inner box etc. will be checked against the required specification details & provide the comparison photos of findings in the report for reference.
Packing and Packaging :
In this Packing & Packaging related details Shipping mark, Method of Packaging, Carton gross weight, Carton dimensions, Carton dryness, Carton fillings, Outer packing etc. will be checked against the required specification details & provide the comparison photos of findings in the report for reference.
On site test :
This test includes Functionality, Safety and regulatory of the product. On-site test results are carried out as per the facility available in the factory and it is not a complete or replacement of Laboratory test results. Onsite tests give a tentative or approximate idea to customers on the functionality of the product. Customers can have further Laboratory tests for precise findings.
