GENERAL
This guide cannot cover every possible contingency, which may develop during a
particular test program. Many questions, which may arise, can be answered by a
complete understanding of the test standards and their intent. When in doubt on any
detail, check with the laboratory manager and be sure you understand the procedures
involved.
It is critical that all spaces on the data forms be properly filled in. Each test must be
represented by a complete record of what was done and when.
