2 G+ _. \: }7 ZThe requirement states that there must be no access to hazardous moving parts in Normal
Condition and no parts must be expelled in Single Fault Condition. Does this mean it is
6 i4 N: w4 u3 H. \acceptable to have access to hazardous parts in Single Fault Condition?
Decision:
Mechanical parts are not subject to Single Fault Condition examination.
Explanation:
Specific tests are included in the standard for strength, e.g. impact hammer test, which
determine the acceptable strength of parts. It is not permissible to remove or presume
