This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

Drafting.

This document is modified to adopt IEC 62275:2022 "Cable ties for electrical installations in cable management systems".

The technical differences between this document and IEC 62275:2022, and the reasons therefor, are as follows.

---The dimensional tolerances for the piston used in the marking test have been increased (see Figure 3) to improve operability;

---ISO 9227:2017 (see 11.2) has been replaced with the normatively referenced GB/T 10125-2021 to adapt to my country's technical conditions.

Increase operability;

---The unnecessary Annex A (see Annex A of IEC 62275:2022) has been removed to increase operability.

The following editorial changes have been made to this document.

---Notes irrelevant to my country have been deleted from sections 3.1, 5.13, 6.2.2, 6.2.3, 6.4.1, Chapter 6, Chapter 10, and 11.1.2;

---The error in the subtitle of Figure 2 in the original IEC document has been corrected (see 5.9) to improve operability;

---The listing method for the ring (loop) tensile strength values in Table 3 has been changed (see 6.2.1) to improve operability;

---The error in the circular shaft for the ring (circle) tensile strength test after aging test has been corrected (see 9.7.2 and 9.7.3) to improve operability.
