Requirements for deformations are found in US-standard product specifications for steel bar reinforcing, such as ASTM A615 and ASTM A706, and dictate lug spacing and height. Fibre-reinforced plastic rebar is also used in high-corrosion environments.
The group developed a standard for the steel used to fabricate rails. In 1961 the name "American Society for Testing and Materials" was adopted. In 2001, ASTM officially changed its name to "ASTM International" and added the tagline "Standards Worldwide". [citation needed] In 2014, the tagline changed to "Helping our World Work better."
Scope of ASTM A53 Standard ASTM A53 is standard specification for pipe, steel, black and hot dipped, zinc-coated, welded and seamless. This specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1⁄8 to NPS 26 [DN 6 to DN 650] (Note 1), inclusive, with nominal wall thickness (Note 2) as given in Table X2.2 ...
Many material or standard specifications include a number of different UNS numbers that may be used within that specification. For example: UNS S30400 (SAE 304, Cr/Ni 18/10, Euronorm 1.4301 stainless steel) could be used to make stainless steel bars ( ASTM A276 ) or stainless steel plates for pressure vessels ( ASTM A240 ) or pipes ( ASTM A312 ).
ASTM A325 is an ASTM International standard for heavy hex structural bolts, titled Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength. It defines mechanical properties for bolts that range from 1 ⁄ 2 to 1 + 1 ⁄ 2 inches (13 to 38 mm) in diameter.
A Publicly Available Specification or PAS is a standardization document that closely resembles a formal standard in structure and format but which has a different development model. [1] The objective of a Publicly Available Specification is to speed up standardization. PASs are often produced in response to an urgent market need. [2]
Under NIJ Standard-0101.07, the velocity used for testing conditioned and unconditioned armor is the same. Armor conditioning procedures are outlined in ASTM E3078 Standard Practice for Conditioning of Hard Armor Test Items. [10] Generally, textile armor material temporarily degrades when wet.
ASTM A500 is a standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is the most commonly specified ASTM standard in the US for hollow structural sections. Another related standard is ASTM A501, which is a hot-formed version of this A500.
