4.4.2.2 Recommended Record Keeping for Periodic Inspections
Adequate records as a part of periodic inspection are essential for the proper use of
calibrated chains. The chain record should include a complete description and
identification of the new chain, the date and results of each inspection, the date and
results of each test and the date and description of any maintenance.
The record is a continuous history of the chain and shows that it has been regularly
inspected and maintained in good operating condition.
When the chain is removed from service, a new record should be prepared for the
replacement chain.
