This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents"
drafting:
This document replaces GB/T 14058-2008 "γ-ray Flaw Detector": Compared with GB/T 14058-2008, except for structural adjustment and editing
In addition to sexual changes, the main technical changes are as follows:
a) Added "sealed radioactive source" (see 3:2), "simulated source" (see 3:3), "source support" (see 3:4), "source assembly" in terms and definitions
(see 3:5), "storage conduit" (see 3:13), "safety monitoring device" (see 3:19), "basic data element" (see 3:20);
b) Some terms and definitions have been changed: "γ-ray flaw detector" (see 3:1, 3:1 of the:2008 edition), "source component safety locking device" (see
3:7, 3:2 of the:2008 edition), "remote control device" (see 3:8, 3:12 of the:2008 edition), "control cable" (see 3:9, 3:4 of the:2008 edition),
"Control cable conduit" (see 3:10, 3:5 of the:2008 edition), "shielding status" (see 3:17, 3:13 of the:2008 edition), "working status" (see
3:18, 3:14 of version:2008);
c) Added power requirements for safety monitoring devices in environmental adaptability (see 5:2);
d) Added technical requirements for safety monitoring devices (see 5:3);
e) Deleted the requirements for the trolley in the safety performance and safety experiment (see 5:3:7 and 6:3:7 of the:2008 edition);
f) The reliability of the safety monitoring device is added to the reliability requirements (see 5:5:5);
g) Increase the safety monitoring device test (see 6:3);
h) The reliability of the safety monitoring device has been increased in the reliability test (see 6:5:5):
