Direct answer: AQL is not simply “less inspection,” and 100% inspection is not necessary for every project. The choice depends on product risk, lot size, cost of defects and client requirements.
When AQL Is Useful
For larger, relatively standardized lots, a client-specified AQL plan provides a repeatable sampling rule. The inspection level, defect classes and accept/reject rule should be defined together.
When a Fixed Sampling Ratio Is Useful
Smaller projects or clients with an internal percentage can use a specified ratio. The important part is to define what is checked and what constitutes a failure before inspection starts.
When to Consider 100% Inspection
Full inspection may be appropriate for high-risk issues, selected post-rework checkpoints, an explicit client requirement, or when sampling exceeds the accepted defect level. Time and labor impact should be assessed.
Do Not Automatically Expand Scope After an Exception
Changsheng first reports issue type, quantity and photos. The client then decides whether to use full inspection, return, rework or another action.
Applicable Boundary
AQL, sampling and full inspection are project inspection methods; none replaces laboratory or certification testing.
How It Connects to Changsheng
Clients can specify AQL or sampling ratios, and Changsheng can execute IQC/OQC to confirmed criteria while linking exceptions to supplier coordination, rework and outbound control.
