Laboratory Controls
Controls that establish scientifically sound specifications, standards, sampling plans, and test procedures so that materials from components to finished products can be judged against them.
Details
This is the title of the subpart in the United States regulation that gathers the testing requirements together, so individual laboratory failures are cited under this name. Most findings use the standard sentence that scientifically sound and appropriate specifications, standards, sampling plans, and test procedures were not established, followed by the absence of the quality control unit review and approval required by 211.160(a), or by records not made at the time of performance. What is examined is not whether the result passed but on what basis the specification was set and who approved it.
