ESTA: Entertainment Services and Technology Association

ESTA, the Entertainment Services and Technology Association, is a nonprofit trade association based in North American for the entertainment technology industry. ESTA engages in skills certification in many of the crafts represented by the IATSE (International Alliance of Theatrical Stage Employees), and develops standards in those areas through an ANSI-accredited Technical Standards Program (TSP). Its industry-leading standards program enjoys international participation and currently has working groups in nine areas: control protocols, electrical power, event safety, floors, fog and smoke, followspot position, photometrics, rigging, and stage machinery. Standards from ESTA 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: or 1-212-642-4980 or Request Proposal Price.

Below are ESTA's best-selling standards. To find additional standards, please use the search bar above.

ANSI E1.21-2020

Entertainment Technology - Temporary Structures Used for Technical Production of Outdoor Entertainment Events

ANSI E1.21 covers temporary structures used for the technical production of outdoor entertainment events. Custom temporary structures supporting performance platforms are included in the scope of this document, but pre-engineered, manufactured, modular staging systems used as platforms for performance, independent of other temporary structures, are not within its scope. This document helps to ensure the structural reliability and safety of these structures, by setting required levels of design and performance parameters, and establishes a reasonable standard for care for their design and use.

ANSI E1.47-2017

Entertainment Technology -- Recommended Guidelines for Entertainment Rigging System Inspections

The standard offers guidance on inspecting entertainment rigging systemsùwhich are systems used to lift and support scenery, luminaires, and other equipment overhead in entertainment venues,such as theatres, video/film studios, amphitheatres, and arenas used for live performances or special eventsùincluding recommended inspector qualifications and responsibilities, scope and frequency of inspections, content of the rigging inspection report, and related information concerning the inspection process.

ANSI E1.11-2008 (R2018)

Entertainment Technology -- USITT DMX512-A -- Asynchronous Serial Digital Data Transmission Standard for Controlling Lighting Equipment and Accessories

This Standard describes a method of digital data transmission between controllers and controlled equipment as described in Clause 1.4 and accessories, including dimmers. It covers electrical characteristics, data format, data protocol, and connector types.

ANSI E1.46-2018

Standard for the Prevention of Falls from Theatrical Stages and Raised Performance Platforms

The users of theatrical stages and raised platforms can suffer debilitating injuries from falls into orchestra pits, open stage lifts, and similar openings in stage floors. Health and safety regulations require action to prevent these falls, but offer little guidance that is suitable for theatrical environments. This document provides that guidance. This revised edition addresses recent changes to 29 CFR 1910 subpart D

ANSI E1.2-2012

Entertainment Technology ù Design, Manufacture and Use of Aluminum Trusses and Towers

ANSI E1.2 describes the design, manufacture, and use of aluminum trusses, towers, and associated aluminum structural components, such as head blocks, sleeve blocks, bases, and corner blocks, used in the entertainment industry in portable structures.

ANSI E1.31-2018

Entertainment Technology - Lightweight streaming protocol for transport of DMX512 using ACN

ANSI E1.31 - 2018, Entertainment Technology - Lightweight streaming protocol for transport of DMX512 using ACN, is a revision of the 2016 standard. It describes a mechanism to transfer DMX512A packets over a TCP/IP network using a subset of the ACN protocol suite. It covers data format, data protocol, data addressing, and network management It also outlines a synchronization method to help ensure that multiple sinks can process this data concurrently when supervised by the same controller. This revision includes support for IPv6 as well as IPv4.

ANSI E1.42-2018

Entertainment Technology—Design, Installation, and Use of Orchestra Pit Lifts

ANSI E1.42-2018 covers the design, construction, operation, inspection, testing, maintenance, alteration and repair of permanently installed orchestra pit lifts and their associated parts, rooms, spaces, enclosures and hoistways, where located in a theatre or a similar place of public entertainment. It supersedes ANSI E1.42-2016.

ANSI E1.6-1-2019

Entertainment Technology - Powered Hoist Systems

ANSI E1.6-1-2019, Entertainment Technology -- Powered Hoist Systems, establishes requirements for the design, manufacture, installation, inspection, and maintenance of powered hoist systems for lifting and suspension of loads for performance, presentation, and theatrical production. This standard does not apply to the structure to which the hoist is attached, to the attachment of loads to the load carrying device, to systems for flying people, to welded link chain hoists, or to manually powered hoists.

ANSI E1.1-2018

Entertainment Technology - Construction and Use of Wire Rope Ladders

ANSI E1.1 - 2018 describes the construction and use of wire rope ladders in the entertainment industry. It is a revision of the 2012 standard, which was a revision of the 2006 standard with changed load ratings to accommodate heavier workers. Wire rope ladders are distinguished from other ladders by having flexible rails. They are used in applications where ladders with rigid rails are impractical to use, or where a rigid ladder would pose a greater danger to the user or other workers in the area.

ANSI E1.11-2004

Entertainment Technology -- USITT DMX512-A -- Asynchronous Serial Digital Data Transmission Standard for Controlling Lighting Equipment and Accessories

ANSI E1.11 describes a protocol based on ANSI/TIA/EIA-485-A-1998 for transmitting digital data to control entertainment lighting equipment and accessories. The standard describes the electrical properties, receiver and transmitter topologies, data format, messages, and connector types. It also addresses network grounding and over-voltage protection.
