Applicability and limitations
The combined tags on the original website include four independent grades: DT4, DT4A, DT4E, and DT4C; this historical tag is retained for product association.; Independent records have already been created for the four grades according to Table 2 of the standard text.. Table A.1 in Appendix A provides only informative heat analysis reference values.; Clause 7.1 requires the provision of chemical analysis but it shall not serve as the basis for delivery acceptance.. The website product records do not specify an applicable year; the 2022 version cannot be identified as the contract standard based on this..
