T/CSTM 01315-2025 Noiseless testing grayscale background sensitivity card
Basic Information
Scope
Scope: This document specifies the design standards, printing specifications, usage methods, markings, and conformity declarations for non-destructive testing gray-scale background sensitivity cards (hereinafter referred to as sensitivity cards). This document is applicable to testing the sensitivity of the human eye in gray-scale backgrounds during non-destructive testing using vision, such as visual inspection and visual observation in magnetic particle testing and penetrant testing. It can also be used as a reference for testing the sensitivity of the human eye in gray-scale backgrounds in other types of testing.
