AWS A5.2-A5.2M:2018 pdf download.Specification for Carbon and Low-Alloy Steel Rods for Oxyfuel Gas Welding
1. Scope
1.1 This specification prescribes requirements for the classification of carbon and low-alloy steel rods for oxyfuel gas welding.
1.2 This specification makes use of both U.S. Customary Units and the International System of Units (SI). The measurements are not exact equivalents; therefore, each system must be used independently of the other without combining in any way when referring to material properties. The specification designated A5.2 uses U.S. Customary Units. The specification designated A5.2M uses SI Units. The latter units are shown within brackets [ ] or in appropriate columns in tables and figures. Standard dimensions based on either system may be used for sizing of filler metal or packaging or both under A5.2 and A5.2M specifications.
1.3 Safety and health issues and concerns are beyond the scope of this standard; some safety and health information is provided, but such issues are not filly addressed herein. Some safety and health information can be found in Annex Clauses A5 and AIO.
Work performed in accordance with this standard may involve the use of materials that have been deemed hazardous, and may involve operations or equipment that may cause injury or death. This standard does not purport to address all safety and health risks that may be encountered. The user of this standard should establish an appropriate safety program to address such risks as well as to meet applicable regulatory requirements. ANSI Z49.1 should be considered when devel-oping the safety program.
2. Normative References
2.1 The documents listed below are referenced within this publication and are mandatory to the extent specified herein.For undated references, the latest edition of the referenced standard shall apply. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply.
6. Rounding Procedure
For the purpose of *determining compliance with the requirements of this standard, the actual test values obtained shall be subjected to the rounding rules of ASTM E29 or Rule A in Clause B.3 of ISO 80000-1 (the results are the same). If the measured values are obtained by equipment calibrated in units other than those of the specified limit, the measured val-ues shall be comverted to the units of the specified limit before rounding. If an average value is to be compared to the specified limit, rounding shall be done only afier calculating the average. An observed or calculated value shall be rounded to the nearest 1000 psi (l ksi) for tensile strength for A5.2, and to the nearest 10 MPa for tensile strength for A5.2M, and to the nearest unit in the last right hand place of figures used in expressing the limiting values for other quantities. The rounded results shall fiulfill the requirements for the classification under test.AWS A5.2-A5.2M pdf download.
