ASME: American Society of Mechanical Engineers

ASME, the American Society of Mechanical Engineers, is a nonprofit membership organization that promotes the art, science, and practice of multidisciplinary engineering and allied sciences around the globe. It develops mechanical engineering standards regarding the proper design, construction, and testing of many mechanical devices, ensuring predictability in production and reliability in use. ASME is an ANSI accredited standards developer. It was founded in 1800 by a small group of leading industrialists and has grown to include more than 130,000 members in 151 countries. 32,000 of the members are students. Standards from ASME are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: [email protected] or 1-212-642-4980 or Request Proposal Price.

ASME Y14.5-2018

Dimensioning and Tolerancing

This Standard establishes symbols, rules, definitions, requirements, defaults, and recommended practices for stating and interpreting dimensioning, tolerancing, and related requirements for use on engineering drawings, models defined in digital data files, and related documents. For a mathematical explanation of many of the principles in this Standard, see ASME Y14.5.1M. Additional uniform practices for applying dimensions, tolerances, and related requirements in digital data sets are defined in ASME Y14.41. Practices unique to architectural and civil engineering and welding symbology are not included in this Standard.

ASME B20.1-2018

Safety Standard for Conveyors and Related Equipment

B20.1 applies to the design, construction, installation, maintenance, inspection, and operation of conveyors and conveying systems in relation to hazards. The conveyors may be of the bulk material, package, or unit handling types where the installation is designed for permanent, temporary, or portable operation. This Standard shall apply, with the exceptions noted below, to all conveyor installations. This Standard specifically excludes any conveyor designed for, installed for, or used primarily for the movement of human beings. This Standard does, however, apply to certain conveying devices that incorporate within their supporting structure work stations or operator’s stations specifically designed for authorized operating personnel.

ASME A13.1-2020

Scheme for the Identification of Piping Systems

A13.1 is intended to establish a common system to assist in identification of hazardous materials conveyed in piping systems and their hazards when released in the environment. This scheme concerns identification of contents of piping systems in industrial and power plants. It is also recommended for the identification of piping systems used in commercial and institutional installations, and in buildings used for public assembly. It does not apply to pipes buried in the ground nor to electrical conduits.

ASME B30.20-2018

Below-the-Hook Lifting Devices

Volume B30.20 includes provisions that apply to the marking, construction, installation, inspection, testing, maintenance, and operation of below-the-hook lifting devices, other than components addressed by other ASME B30 volumes or other standards, used for attaching loads to a hoist. The requirements in this Volume also apply to clamps used for positioning and anchoring.

ASME A17.1/CSA B44-2019

Safety Code for Elevators and Escalators

This Code covers the design, construction, operation, inspection, testing, maintenance, alteration, and repair of the following equipment and its associated parts, rooms, spaces, and hoistways, where located in or adjacent to a building or structure (see Section 1.2): (a) hoisting and lowering mechanisms, equipped with a car, that move between two or more landings. This equipment includes, but is not limited to, elevators (see Section 1.3). (b) power-driven stairways and walkways for carrying persons between landings. This equipmentincludes, butis not limited to, escalators and moving walks (see Section 1.3). (c) hoisting and lowering mechanisms equipped with a car that serves two or more landings and is restricted to the carrying of material by its limited size or limited access to the car. This equipment includes, but is not limited to, dumbwaiters and material lifts; it does notinclude vertical reciprocating conveyors (see Section 1.3).

ASME Y14.100-2017

Engineering Drawing Practices

This Standard establishes the essential requirements and reference documents applicable to the preparation and revision of manual or computer-generated engineering drawings and associated lists, unless tailored by a specialty standard. It is essential that this Standard be used in close conjunction with ASME Y14.24, ASME Y14.34, ASME Y14.35, and ASME Y14.41.

ASME BTH-1-2020

Design of Below-the-Hook Lifting Devices

BTH-1 provides minimum structural and mechanical design and electrical component selection criteria for ASME B30.20 below-the-hook lifting devices. The provisions in this Standard apply to the design or modification of below-the-hook lifting devices. Compliance with requirements and criteria that may be unique to specialized industries and environments is outside of the scope of this Standard. Lifting devices designed to this Standard shall comply with ASME B30.20, Below-the-Hook Lifting Device. B30.20 includes provisions that apply to the marking, construction, installation, inspection, testing, maintenance, and operation of below-the-hook lifting devices. BTH-1 addresses only design requirements. As such, this Standard should be used in conjunction with B30.20, which addresses safety requirements. BTH-1 does not replace B30.20. The design criteria set forth are minimum requirements that may be increased at the discretion of the lifting device manufacturer or a qualified person. Key changes to this revision of BTH-1 include: Addition of chapter of requirements for Lifting Magnet Design with additional commentary found in a corresponding new Nonmandatory Appendix; Addition of design requirements for new Design Category for specialized application in industries that require lifting designs based on a specified larger Design factor Addition of new requirements for Member Properties; Updated Table 3-2.2-1 Limiting Width-Thickness Ratios for Compression Elements. BTH-1 and B30.20 are to be used in conjunction with equipment described in other volumes of the ASME B30 series of Safety Standards. Careful application of these Safety Standards will help users to comply with applicable regulations within their jurisdictions, while achieving the operational and safety benefits to be gained from the many industry best-practices detailed in these volumes. Intended for manufacturers, owners, employers, users and others concerned with the specification, buying, maintenance, training and safe use of below-the-hook lifting devices with B30 equipment, plus all potential governing entities.

ASME B30.26-2015 (R2020)
