Handle the masonry hammer test report QB T 129010. Inspection requirements.
1. Overview. The masonry hammer is a tool widely used in the construction, quarrying and mining industries, and its quality and performance are of great significance for the safety and efficiency of the project. In order to ensure that the quality and performance of the masonry hammer meets the relevant standards, a series of inspections and tests are required. This article will introduce in detail the hammer quality inspection requirements for handling the masonry hammer test report, including the test items, testing methods, testing standards and judgment basis.
Second, the test items.
Hammer quality inspection according to QB T 129010 standards, the test items of the masonry hammer test report should include the following aspects:
1.Appearance quality: Check whether the appearance of the masonry hammer is smooth and smooth, and there are no obvious scratches, dents, cracks and other defects.
2.Dimensional inspection: measure the dimensions of the masonry hammer, including length, width, height, hole diameter, etc., to ensure that it meets the design requirements.
3.Material quality inspection: Conduct quality inspection on the materials used in the masonry hammer, including the composition and mechanical properties of the materials, to ensure that the quality of the materials meets the relevant standards.
4.Hardness testing: The surface hardness of the masonry hammer is tested by a hardness tester to ensure that it has sufficient hardness and wear resistance.
5.Impact performance test: The impact test of the masonry hammer is carried out by the drop weight impact testing machine to test its impact resistance and stability.
6.Durability test: Through long-term use or durability test, check whether the masonry hammer has enough durability and stability.
3. Hammer quality inspection methods and standards.
In the process of handling the masonry hammer test report, it is necessary to adopt the correct testing methods and judgment standards to ensure the accuracy and reliability of the test results. The specific requirements are as follows:
1.Appearance quality: Visual inspection is used to observe whether there are defects in the appearance of the masonry hammer. The judgment criterion is that there are no obvious defects and meets the design requirements.
2.Dimensional inspection: Measurement is carried out with measuring tools to obtain accurate dimensional data. The judgment criterion is that all dimensions should meet the design requirements, and a certain margin of error is allowed.
3.Material quality inspection: chemical analysis, metallographic analysis, mechanical property testing and other methods are used for testing. The judgment criterion is that the composition, mechanical properties and other indicators of the material should meet the requirements of the relevant standards.
4.Hardness testing: use hardness tester for testing, such as Vickers hardness tester, Rockwell hardness tester, etc. The judgment criterion is that the hardness value should meet the requirements of the relevant standards.
5.Impact performance test: The impact test is carried out by using a drop weight impact testing machine to test the impact resistance and stability of the masonry hammer. The judgment criterion is that the impact energy generated by the impact hammer falling at the specified height on the masonry hammer should meet the requirements of the relevant standards, and the masonry hammer should not be damaged, such as cracking and deformation.
6.Durability test: Tested by long-term use or durability test to verify the durability and stability of the masonry hammer. The judging criterion is that under the specified use conditions, the masonry hammer should be able to maintain its basic performance and stability, without obvious wear and damage.
4. Basis for judgment and issuance of report.
In the process of handling the masonry hammer test report, it is necessary to make judgments according to relevant standards and regulations to ensure the accuracy and reliability of the test results. The specific requirements are as follows:
1.Judgment basis: should be based on QB T 129010 standards are the main basis for judgment, and comprehensive judgment is made in combination with other relevant standards and regulations.
