How does sampling work during an inspection?
Pro QC recommends ANSI Z1.4 2003 sampling tables to determine the number of units that will be randomly selected for evaluation. Based on the lot or batch size, code letters are assigned that cross-reference to the sample size required depending on which plan is being employed. Single and double normal sampling plans are the most commonly used. If you do not have existing sampling requirements, Pro QC will assist you in determining which plan works best for your specific needs. Samples are checked against a detailed inspection plan for appearance, applicable functionality, packaging integrity, workmanship, etc. If you currently do not have an inspection plan, Pro QC can assist. Defects noted are classified as major, minor, or critical depending on inspection plans. The acceptable quality level (AQL) is determined by totaling the defects and using the corresponding accept/reject criteria within the sampling plan.

EIS recommends ANSI Z1.4 2003 sampling tables to determine the number of units that will be randomly selected for evaluation. Based on the lot or batch size, code letters are assigned that cross-reference to the sample size required depending on which plan is being employed. Single and double normal sampling plans are most commonly used. If you do not have existing sampling requirements, EIS will assist you in determining which plan works best for your specific needs. Samples are checked against a detailed inspection plan for appearance, applicable functionality, packaging integrity, workmanship, etc. If you currently do not have an inspection plan, EIS can assist you in developing one. Defects noted are classified as major, minor or critical depending on inspection plans. The acceptable quality limit (AQL) is determined by totaling the defects and using the corresponding accept/reject criteria within the sampling plan.
