Product Code:SAE AMS2630
Title:Inspection, Ultrasonic, Product Over 0.5 Inch (12.7 mm) Thick
Issuing Committee:Ams K Non Destructive Methods And Processes Committee
Scope:This specification covers procedures for ultrasonic inspection, by pulse-echo procedures, of flat, rectangular, round, cylindrical, and contoured products having a thickness or cross-sectional dimension greater than 0.50 inch (12.7 mm), using either contact or immersion methods, and using the longitudinal-wave or shear-wave modes or combinations of the two, as necessary. This specification may apply to testing finished machined parts provided the parts can meet the basic testability requirements, such as size, contour, metallurgical structure, and thickness.Product Code:SAE J765
Title:Crane Load Stability Test Code
Issuing Committee:Cranes And Lifting Devices Committee
Scope:This SAE Standard may be used for all revolving cranes wherein the capacity of the crane to support loads is based on its resistance to overturning. it is not applicable to cranes wherein the capacity of the crane is based on structural strength or available hoisting power.The purpose of this test is to determine the maximum capacity of a crane to counterbalance loads applied on its hook block. The capacity of the crane is reported in terms of the load in kilograms (pounds) and its corresponding radius in meters (feet) for a specified position of the upperstructure with respect to the mounting.
