Testing & Inspection Foundations

Requirements, inspection planning, sampling, traceability, uncertainty and documentation.

How requirements, sampling, measurement, inspection, testing, records and disposition fit together.

Distinguish measurement, inspection and test activities without treating the terms as interchangeable.

How process confidence and product verification serve different roles.

Define what is inspected, when, by whom, with which method and against what criteria.

How planned verification points organize manufacturing and construction quality evidence.

Why a measurement result is not meaningful until it is compared with an approved requirement.

Why a sample must represent the lot, process or material question being asked.

Connect material, specimen, instrument, method, operator and result.

Why every quantitative measurement has a range of plausible values rather than perfect exactness.

Separate variation from repeated measurements and variation between people, systems or conditions.

Match the physical characteristic, material, geometry, defect type and decision to the method.

Why records need identity, method, equipment, result, units and disposition.
