Prestressed concrete lintels are not covered by this standard.

For further guidance, refer to Building Code Requirements for Masonry Structures, TMS 402. Therefore, this standard does not address issues related to such. Concrete masonry lintels are not typically manufactured using shear reinforcement (stirrups or other vertical reinforcement). Due to building code imposed limitations on the design of masonry lintels, all lintels must contain reinforcement. NOTE 1-This specification covers only concrete masonry lintels containing reinforcement. These lintels are suitable for both loadbearing and nonloadbearing applications. The law makes the ASTM F963 standard a mandatory requirement for toys while the Consumer Product Safety Commission (CPSC) studies the standard's effectiveness and issues final consumer guidelines for toy safety.This specification covers concrete masonry lintels (beams) that are solid in cross-section, are reinforced for flexure, and are made from hydraulic cement, water, and mineral aggregates with or without the inclusion of other materials.
The standards, however, may become mandatory when referenced by an external contract, corporation, or government. ASTM International has several awards for contributions to standards authorship, including the ASTM International Award of Merit (the organization's highest award) ASTM International is classified by the United States Internal Revenue Service as a 501(c)(3) nonprofit organization.ĪSTM International has no role in requiring or enforcing compliance with its standards. The members serve on one or more of 140+ ASTM Technical Committees. Members can, however, participate without a formal vote and their input will be fully considered.Īs of 2015, ASTM has more than 30,000 members, including over 1,150 organizational members, from more than 140 countries. Because of these restrictions, there can be a substantial waiting-list of producers seeking organizational memberships on the more popular committees. In order to meet the requirements of antitrust laws, producers must constitute less than 50% of every committee or subcommittee, and votes are limited to one per producer company. Users include industry users, who may be producers in the context of other technical committees, and end-users such as consumers. The latter includes academics and consultants. Members are classified as users, producers, consumers, and "general interest". Membership in most committees is voluntary and is initiated by the member's own request, not by appointment nor by invitation. Standards are developed within committees, and new committees are formed as needed, upon request of interested members. Membership in the organization is open to anyone with an interest in its activities. Now, ASTM International has offices in Belgium, Canada, China, Peru, and Washington, D.C.
In 2014, it changed the tagline to "Helping our World Work better". In 2001, ASTM officially changed its name to “ASTM International" and added the tagline "Standards Worldwide". Originally called the "American Society for Testing Materials" in 1902, it became the "American Society for Testing And Materials" in 1961. The group developed a standard for the steel used to fabricate rails. A group of scientists and engineers, led by Charles Dudley, formed ASTM in 1898 to address the frequent rail breaks affecting the fast-growing railroad industry.
