Uniformat is a standard for classifying building specifications, cost estimating, and cost analysis in the U.S. and Canada. The elements are major components common to most buildings. The system can be used to provide consistency in the economic evaluation of building projects.
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 ).
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications.
Process piping and power piping are typically checked by pipe stress engineers to verify that the routing, nozzle loads, hangers, and supports are properly placed and selected such that allowable pipe stress is not exceeded under different loads such as sustained loads, operating loads, pressure testing loads, etc., as stipulated by the ASME B31, EN 13480, GOST 32388, RD 10-249 or any other ...
The alloy number is simply a general classifier, whereas it is the specification itself that narrows down the steel to a very specific standard. The SAE steel grade system's correspondence to other alloy numbering systems, such as the ASTM-SAE unified numbering system (UNS), can be seen in cross-referencing tables (including the ones given below).
A standard specification is an explicit set of requirements for an item, material, component, system or service. It is often used to formalize the technical aspects of a procurement agreement or contract. [2] For example, there may be a specification for a turbine blade for a jet engine that defines the exact material and performance requirements.
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 ...
Other governments have also referenced ASTM standards. [9] Corporations doing international business may choose to reference an ASTM standard. All toys sold in the United States must meet the safety requirements of ASTM F963, Standard Consumer Safety Specification for Toy Safety, as part of the Consumer Product Safety Improvement Act of 2008 ...
