-All tools not in regular use shall be similarly checked every 12 months to the gauging requirements.
 -When a tool becomes due for a 1000 crimp or yearly check it shall not be used again, until the results of the test interval are known and the tool certified for use.
 B. Gauging of Tools : (Ref. Fig. 004) Each tool or die shall be tested by the insertion of GO/NO GO gauge.
 (1)
 Example:
 Gauge part number : M22520/3-1

 (2)
 Procedure:

 -A GO-NO GO gauge is used to check condition of crimping tool. When tool handles are squeezed, the GO element must pass through the dies, the NO-GO element must not pass.
 -Only one gauge is necessary for periodic in-service inspection of crimping tool, examples:
