Foreword
This standard replaces GB/T 1942-1991 "Test Method for Wood splitting force anti."
This standard compared with GB/T 1942-1991 The main changes are as follows.
--- Amend Chapter 3, on one end of the sample perpendicular to the direction of the wood grain tension is applied, the specimen along the grain split (between 1991 and the present
Version 3);
--- 4.2 Modify measurement tools vernier caliper or other measuring tools (1991 edition and 4.2);
--- 6.1 modify, measure the width of the face to face anti sample (1991 edition and 6.1) in the center hole;
--- Remove 6.2 "will fill the failure load into Appendix A (Supplement) records in the table" (1991 edition and 6.2);
--- Amend Chapter 7 q c is a sample of the anti-splitting force (1991 edition and 7);
--- Edit "8 recording and reporting test results", according to the test results recorded in Appendix A fill; the test report according to GB/T 1928-
7.4 prescribed contents written in 2009 (1991 edition and 8);
--- Increase in Appendix A test site, remove the anti-splitting force (1991 edition and Appendix A).

Wood cleavage strength test method
1 Scope
This standard specifies the determination timber cleavage strength test equipment, samples, test procedures, test results and the results of the calculation and reporting records.
This standard applies to small sample timber unblemished anti-splitting test.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
GB/T 1928-2009 physical and mechanical test methods - General
GB/T 1929-2009 physical and mechanical test materials and test specimens sawing method
Principle 3
Simulated wood ax biased state, at one end of the sample perpendicular to the direction of the wood grain tension is applied, the sample split along the grain, to determine the wood
The ability to split the anti-material.
4 Test Equipment
4.1 test machine, load measurement accuracy should be consistent with GB/T 1928-2009 requirements in Chapter 6, and has adapted to sample the wedge-shaped notch
Test accessories.
4.2 Measurement tools vernier caliper or other measuring tools, measurements should be accurate to 0.1mm.
5 Sample
5.1 test material sawing and test specimens shall comply with GB/T 1929-2009 the provisions of Chapter 3. The shape and size of the sample, according to the provisions of FIG. 1
Production.
5.2 In the production of the wedge cut, drill press icon on the specimen. Diameter surface anti-split samples, drilling radial direction of the growth ring; anti-chord plane split again
Thus, the growth direction of drilling wheel tangential direction, and then along the length of the sample line connecting the centers of two bores direction sawn, shown in Figure 1.
