Tests performed must be defined on the certificate.


"Tests performed must be defined on the certificate. Completeness suggests that all tests be noted on the certificate so that there is no doubt as to the thoroughness of the survey.

Most authorities that specify tests express or imply that “such other tests as the surveyor deem appropriate” should be done. Therefore, the certificate should include a notation of all tests such as no load, partial load, full proof load, line pull, and any tests done on accessories such as jibs and auxiliary hoists.

If proof tests are not required, the surveyor is wise to use the partial load functional test at an authorized radius for the load and line pull tests for diagnostic purposes, thus demonstrating due diligence (this applies to mobile cranes)."
