ASTM A213 Standard Scope
1.1 Haec specificatio tegit sesutilem ferriticum et austeniticum ferrum boiler, superheater, et fistulae caloris commutatoris, designati Gradus T91, TP304, etc. Hi ferrei in tabulis 1 et 2 recensentur.
1.2 Gradus literae, H in designatione habentium diversitatem requiruntur ab iis qui similes gradus litterae non continentur, H. Haec diversa requiruntur altiores vires subrepentes, quam regulariter in similibus gradibus sine his diversitate requisitis.
1.3 Tubingae magnitudines et crassitudines huic specificationi plerumque praestandae sunt 1/8 in. [3.2 mm] in diametro intus ad 5 in. [127 mm] extra diametrum et 0.015 ad 0.500 in [0.4 ad 12.7 mm], inclusive; crassitudo parietis minimae vel, si ordine specificata est, parietis mediocris crassitudo.Tubings alias diametros habens praestari potest, si tales fistulae omnibus aliis requisitis hanc specificationem pareant.
1.4 Valores, quae in unitatibus vel SI vel inch-mina unitatibus statuuntur, separatim ut vexillum considerandae sunt.In textu, SI unitates in uncis ostenduntur.Valores in unaquaque ratione statuti aequivalentias exigere non possunt;ergo utraque ratio sine altero utetur.Coniungentes valores e duobus systematis inveniantur in non-conformitate cum mensura.Unitates unciarum pondo adhibeant, nisi designatio "M" huius specificationis in ordine specificetur.

B Licet iubere T2 et T12 contento sulphuris 0.045 max..
C Vel, pro hac ratione minima, materia minimam duritiem 275 HV habebit in dura conditione, ut post austen- sionem et refrigerationem ad cella temperiem, sed ante temperantiam definiatur.Duritia probatio fiet in media crassitudine producti.Duritia test frequentiae duo genera tractationis producti per calorem multum erunt et durities eventus probationis in fama materiali nuntiabuntur.
