The ASME B16 Standardization of Valves Flanges, Fittings and Gaskets Committee, which operates under ASME’s Board on Pressure Technology Codes and Standards is responsible for standards covering valves, flanges, pipe fittings, gaskets and valve actuators for use in pressure services.
The American Welding Society (AWS) publishes over 240 AWS-developed codes, recommended practices and guides which are written in accordance with American National Standards Institute (ANSI) practices. [1] The following is a partial list of the more common publications: [citation needed]
The ANSI/APSP (Association of Pool & Spa Professionals) standards used for pools, spas, hot tubs, barriers, and suction entrapment avoidance. The ANSI/HI (Hydraulic Institute) standards used for pumps. The ANSI for eye protection is Z87.1, which gives a specific impact resistance rating to the eyewear. This standard is commonly used for shop ...
Class II valves have no more than 0.5% leakage with 50 psi (340 kPa) (or less if operating pressure is less) of air pressure at the operating temperature; Class III valves have no more than 0.1% leakage under those conditions; this may require soft valve seats, or lapped metal surfaces; Class IV valves have no more than 0.01% leakage under ...
The pressure vessels can be either fired or unfired. [17] The pressure may be from external sources, or by the application of heating from an indirect or direct source as a result of a process, or any combination of the two. [18] The rules contained in this section can be used as an alternative to the minimum requirements specified in Division 1.
In electric power systems and industrial automation, ANSI Device Numbers can be used to identify equipment and devices in a system such as relays, circuit breakers, or instruments. The device numbers are enumerated in ANSI / IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations .
A plumbing code is a code that provides regulations for the design, installation and inspection of building plumbing and sanitary systems. In the United States, jurisdictions enact their own codes, some of which are based upon model plumbing codes.
The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15. The number is sometimes followed by a letter, indicating that components are grouped or matched with each other, e.g. R17A, R17B. The IEEE 315 standard contains a list of Class Designation Letters to use for electrical and electronic ...
