This standard is a free download.Approved: February 11, 2021, Updated September 9, 2025.This document provides a comprehensive dictionary of data identifiers (DIs), and provides for the assignment of new DIs, when required. A DI is a specified character or string of characters that defines the general category or intended use of the data that follows. DIs can be used in automatic identification and data capture (AIDC), Internet of Things (IoT), Blockchain, or other similar applications. DIs described in this document consist of a capital letter (A through Z), optionally preceded by one-, two-, or three digits (0 through 9). DIs are succeeded by a string of letters, numbers, and/or symbols of a length and composition that can vary from DI to DI, which encode specific information pertinent to the item being encoded.This standard is updated periodically when new DI requests are processed.
Price: $150.00The purpose of this standard is to specify the minimum requirements for the structural design, testing, and utilization of industrial steel cantilevered storage racks. A cantilevered rack is a storage system designed to store long, bulky, or irregular materials of almost any length. Cantilevered racks generally consist of freestanding columns connected to fixed bases that are anchored to the floor. Load arms cantilever from the column to create storage levels, with loads placed directly onto the arms. Columns are spaced to adequately support loads.
Price: $50 This standard provides a test method for characteristics for topple barriers, including their ability to resist loads imposed upon them. The standard addresses both rigid (non-flexible) and non-rigid (flexible) topple barriers.This standard provides a consistent test method that provides results so consumers can make an informed purchase decision when selecting topple barriers for their application.
Price: $25.00This standard applies to underhung cranes whose end trucks operate on the internal flange of a runway using enclosed track section; and to trolleys (carriers) operating on single-track monorail systems, including all curves, switches, transfer devices, lift and drop sections, and associated equipment. Systems used for transporting personnel require special considerations and are not included in these specifications. This standard does not apply to underhung cranes whose end trucks operate on the lower flange of a patented-track runway section. Refer to ANSI MH27.1-2025, Patented Track Underhung Cranes and Monorail Systems for patented-track runway sections and patented-track monorail systems.Hoist(s) or carrier(s) may be supplied by the crane manufacturer, crane distributor, crane installer, or by the user. In either case, the applicable portions of ASME/ANSI B30.16, Overhead Hoists (Underhung); ASME B30.17, Cranes and Monorails (With Underhung Trolley or Bridge) and appropriate ASME HST Performance Standards apply to the hoist(s) or carrier(s). If the hoist(s) or carrier(s) are supplied by the user, the crane builder shall be provided with certified dimensional drawings with all required data including wiring diagrams, carrier collector locations and weights.This standard includes considerations for cranes and monorail equipment only. It does not include considerations or specifications for the design of the building, the design of supporting structure, electrical power supply, or erection.This standard applies to systems operating in normal ambient temperatures and atmospheric conditions; any other conditions require special consideration.
