Re: [MW:35023] I want to know the RT 10% acceptance criteria.

Dear Yasoob,

The statement appears to relate to a quality control or inspection procedure. Here's a more precise interpretation of the process:

1. First Test:

   • If one item fails out of a sample with a 10% failure rate, a secondary check (referred to as "Trecer" which might be a typo or specific jargon, possibly meant to be "Tracer") is performed with two additional items.

2. Second Test:

   • If either of the two additional items also fails, it indicates a problem, and the entire batch (or "full lot") must be inspected.

Here's a refined version of the process:

Initial Inspection:

• If 10% of the items in the sample fail the initial inspection, perform a secondary inspection with two additional items.

Secondary Inspection:

• If one or both of the two additional items fail this inspection, conduct a full inspection of the entire lot.

This process ensures that if an initial small sample indicates a potential quality issue, further scrutiny is applied to confirm the problem before deciding to inspect the entire batch, thus preventing defective items from proceeding further in the production or distribution process.

Dear Sir,

RT If one fails in 10% then there is a Trecer of two. And second time fails then check the full lot.
