Title:Tolerances, Metric, Corrosion and Heat Resistant Steel Tubing (Cancelled Sep 2007, Superseded by AMS2243)
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers manufacturing tolerances applicable to seamless and welded tubing of corrosion and heat resistant steel ordered to metric dimension. These tolerances apply to all conditions and are based on individual measurements, unless otherwise noted. Tubing may be specified by two dimensions only (OD and wall thickness, ID and wall thickness, or OD and ID).【英文标准名称】:StandardTestMethodforIndirectMeasurementsofDischargebyStep-BackwaterMethod
