NB/T 11517-2024 Nondestructive inspection methods and criterions for important load-bearing components of mining hoisting conveyance
Abstract
This document specifies the general requirements for non-destructive testing of important load-bearing components of mining hoisting containers (cage, bucket, balance hammer, etc.), ultrasonic testing methods, magnetic particle testing methods, determination rules, and principles for dividing non-destructive testing areas.
This document applies to non-destructive testing of important load-bearing components of mining hoisting containers. Similar devices such as the headstock shaft and inclined shaft hoisting connectors can refer to this document for non-destructive testing.
This document does not apply to coarse-grained materials such as austenitic stainless steel and gray cast iron.
