Compared with.2002, in addition to structural adjustments and editorial changes, the main technical changes are as follows.
a) The content of “Scope” in this document has been changed (see Chapter 1, Chapter 1 of the.2002 edition);
b) Added a section on terms and definitions (see Chapter 3);
c) “Test Principles” was changed and made into an independent chapter (see Chapter 4, 2.1 of the.2002 edition);
d) “Device” was changed and made into an independent chapter, the title was changed to “Instruments and Equipment”, and the requirements for measuring instruments were added (see Chapter 5,
2.2 of the.2002 edition);
e) Added the dimension "L = 25.0 mm ± 0.2 mm" in the device drawings (see Figure 1, Figure 1 of the.2002 edition);
f) The sample was changed into a separate chapter, the title was changed to "Sample", and the sample requirements were changed (see Chapter 6,.2002 Edition).
2.3);
g) Added the conditions in which samples are not allowed to be tested (see 6.4);
h) The “Test Procedures” section was changed and made into a separate chapter, and the contents of the procedures were modified (see Chapter 7, 2.4 of the.2002 edition);
i) Changed “-100 mesh spherical powder” to replace “spherical powder” (see 7.3, 2.4.3 of the.2002 edition);
j) “Test Results” was changed and made into a separate chapter, and numerical rounding was added (see Chapter 8, 2.5 of the.2002 edition);
k) The units of “sample width” and “sample thickness” in the calculation formula for transverse rupture strength have been changed (see 8.1, 2.5 of the.2002 edition);
l) Added the “Uncertainty” chapter (see Chapter 9);

Determination of transverse rupture strength of sintered metal friction materials
1 Scope
This document describes the method for the determination of the transverse rupture strength of sintered metallic friction materials.
This document applies to the determination of the fracture strength of rectangular specimens of sintered metallic friction materials under transverse uniform loading under controlled conditions.
2 Normative references
The contents of the following documents constitute the essential clauses of this document through normative references in this document.
For referenced documents without a date, only the version corresponding to that date applies to this document; for referenced documents without a date, the latest version (including all amendments) applies to
This document.

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
transverse rupture strength
Rtr
Place a sample of a certain shape and size flat on two supports at a specified distance, and apply a static load concentrated at the midpoint of the support until the sample
The stress per unit area of the sample cross section at fracture.
Note. The unit is MPa.
4 Test Principle
The test method in this document adopts the principle of strength determination of simply supported beams loaded with three-point bending.
a) The support and loading of the test device on the sample conform to the setting of a simply supported beam with concentrated load at the center point.
b) The test device loads the sample at the midpoint of the support by slowly and steadily flowing powder into the container until the sample breaks.
The process can be used to determine whether the sample can withstand static load.
5 Instruments and Equipment
5.1 Test apparatus
The test device for transverse rupture strength is shown in Figure 1.
