When you buy burner caps by the carton, you cannot inspect every single piece. AQL — Acceptable Quality Level — sampling gives you a statistical way to verify a batch meets your standard without checking everything. Here is how to apply it to burner cap orders.
AQL defines the worst quality level you are willing to accept. A typical import order uses AQL 2.5 for major defects and AQL 4.0 for minor defects. You draw a sample according to the batch size, inspect it, and accept or reject the whole lot based on how many defective pieces you find.
Measure the outer diameter against the SABAF-compatible spec (#130/#100/#75/#55), verify the surface finish matches your order (glossy flat, glossy concave, or matte flat), check the enamel for chips, and confirm the cap sits flat with no wobble.
A reliable factory runs its own inline inspection so that what reaches you already meets the standard. THREEMI manufactures burner caps with consistent tolerances and supports third-party or pre-shipment inspection on request — so your AQL sampling confirms quality rather than catching surprises.
