4.2 Symbol for the Chemical Composition
The numerical symbols or A WS Classification in Table I indicates the chemical composition of the solid wire or rod, determined under conditions given in Clause 6. The first two digits indicate the alloy group. See Annex A for an explanation of the numerical symbols. The second column (A WS AS. 16/AS. 16M Classification) is for reference to previous rei’isions of ihi.c .cpecijwaiion.
4.3 Rounding-Off Procedure
For the purpose of determining compliance with the requirements of this standard, the actual test values obtained shall be subjected to the rounding-off rules of ASTM E29. Standard Practice ftr U.sing Significant Digits in Test Data to Determine Conformance with Specifications or Rule A in Clause B. 3 of ISO 80000—i: 2009 (the results are the same). If the measured values are obtained by equipment calibrated in units other than those of this standard, the measured values shall be converted to the units of this standard before rounding-off. If an average value is to be compared to the requirements of this standard, rounding-off shall be done only after calculating the average. In the case where the testing standard cited in the normative references of this standard contains instructions for rounding-off that conflict with the instructions of this standard, the rounding-off requirements of the testing standard shall apply. The rounded-off results shall fulfill the requirements of the appropriate table for the classification under test.
5. Mechanical Properties
Mechanical properties of weld metal or welded joints are not part of this classification.
6. Chemical Analysis
Chemical analysis shall be performed on specimens of the product or the stock from which it is made. See also footnote c to Table I. Many approved analytical techniques are applicable but, in case of a dispute, reference shall be made to established published methods, agreed upon between the contracting parties.
7. Retest
If any test fails to meet the requirement, that test shall be repeated twice. The results of both retests shall meet the requirement. Specimens for the retest may be taken from the original test sample or from a new test sample. For chemical analysis, retests need be only for those specific elements that failed to meet their test requirement. If the results of one or both retests fail to meet the requirement, the material under test shall be considered as not meeting the requirements of this specification for that classification.
In the event that, during preparation or atier completion of any test, it is clearly determined that prescribed or proper procedures were not followed in preparing the weld test sample or test specimen(s), or in conducting the tests, the test shall be considered invalid, without regard to whether the test was actually completed, or whether the test results met, or failed to meet, the requirement. That test shall be repeated. fol lowing proper prescribed procedures. In this case, the requirement for doubling the number of test specimens does not apply.
8. Technical Delivery Conditions
Technical delivery conditions shall meet the requirements in AWS AS.OIM/A5.O1(!SO 14344 MO!)) and AWS A5.02/AS.02M, or ISO 544 and ISO 14344.AWS A5.16/A5.16M  pdf download.
