The most recent standard is "Standards and Practices for All Appropriate Inquiries" 40 Code of Federal Regulations, Section 312 [1] which drew heavily from ASTM E1527-13, which is the ASTM Standard for conducting 'All Appropriate Inquiry' (AAI) for the environmental assessment of a real property. Previous guidances regarding the ASTM E1527 ...
The A36 (UNS K02600) standard was established by the ASTM International. The standard was published in 1960 and has been updated several times since. [ 2 ] Prior to 1960, the dominant standards for structural steel in North America were A7 (until 1967 [ 3 ] ) and A9 (for buildings, until 1940 [ 4 ] ). [ 5 ]
For alloys in general (including steel), unified numbering system (UNS) of ASTM International and the Society of Automotive Engineers (SAE). American steel grades : AISI/SAE steel grades standard; British Standards; International Organization for Standardization ISO/TS 4949:2016; European standards – EN 10027
ASTM International, formerly known as American Society for Testing and Materials, is a standards organization that develops and publishes voluntary consensus technical international standards for a wide range of materials, products, systems and services. Some 12,575 apply globally.
The Unified Numbering System for Metals and Alloys (UNS) is an alloy designation system widely accepted in North America.Each UNS number relates to a specific metal or alloy and defines its specific chemical composition, or in some cases a specific mechanical or physical property.
AASHTO Soil Classification System (from AASHTO M 145 or ASTM D3282) General Classification Granular Materials (35% or less passing the 0.075 mm (No. 200) sieve) Silt-Clay Materials (>35% passing the 0.075 mm (No. 200) sieve) Group Classification A-1 A-3 A-2 A-4 A-5 A-6 A-7 A-1-a A-1-b A-2-4 A-2-5 A-2-6 A-2-7 A-7-5 A-7-6 Sieve Analysis, % passing
Alloy 20 is an austenitic stainless steel containing less than 50% iron developed for applications involving sulfuric acid.Its corrosion resistance also finds other uses in the chemical, petrochemical, power generation, and plastics industries.
The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International.. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
