GB/T 46551-2025Test method of solid rivets for aerospace (English PDF)

Foreword

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 ISO 17057:1999 "Aerospace solid rivets - Test methods".

This document includes a new chapter on "Terms and Definitions".

The technical differences between this document and ISO 17057:1999, and the reasons therefor, are as follows.

---A description of double-cutting has been added to the scope (see Chapter 1) to maintain consistency with the rest of the text;

---ISO 7500-1:1999 (see 4.1.1) has been replaced with the normatively referenced GB/T 16825.1 to adapt to my country's technical conditions;

---The fixture hardness has been changed from 530HV30 to a hardness of not less than 52HRC (see 4.1.2) to maintain consistency with the technical requirements of current Chinese standards.

Consistent;

---The requirement that "the surface roughness Ra is not greater than 0.2 µm" has been added (see 4.1.2), which is consistent with the technical requirements of the current Chinese standards.

The following editorial changes have been made to this document.

---The standard name has been changed to "Test Methods for Solid Rivets for Aerospace Use";

---Formula numbering has been added and the explanations within the formulas have been standardized;

---The representation of the structure diagram 1 has been changed and all symbols appearing in Figure 1 have been indexed and explained;

---The dimensional requirements in Figure 1 of ISO 17057:1999 are now described in Table 1.
