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 E1.11-2008 (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 E1.21-2013

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

E1.21 establishes a minimum level of design and performance parameters for the design, manufacturing, use and maintenance of temporary ground supported structures used in the production of outdoor entertainment events. The purpose of this guidance is to ensure the structural reliability and safety of these structures and does not address fire safety and safe egress issues.

ANSI E1.20 - 2010

Entertainment Technology-RDM-Remote Device Management over USITT DMX512 Networks

ANSI E1.20 - 2010, Entertainment Technology-RDM-Remote Device Management over USITT DMX512 Networks, describes a method of bi-directional communications over a USITT DMX512/1990 or ANSI E1.11 - 2004 data link between an entertainment lighting controller and one or more remotely controlled lighting devices. The protocol was written to work with the ANSI E1.11-2004 control standard, but will work equally well with the current 2009 version of E1.11. It allows discovery of devices on a DMX512/E1.11 network and the remote setting of DMX starting addresses, as well as status and fault reporting back to the control console. The 2010 edition corrects errors in the 2006 edition, and adds a new message.

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 E1.26-2006 (R2017)

Entertainment Technology - Recommended Testing Methods and Values for Shock Absorption of Floors Used in Live Performance Venues

ANSI E1.26 - 2006 (R2017), Entertainment Technology - Recommended Testing Methods and Values for Shock Absorption of Floors Used in Live Performance Venues, describes a method for measuring how stiff a performance floor is. It also suggests some ranges that have been found to be acceptable-neither too stiff nor too springy.

ANSI E1.4-1-2016

Entertainment Technology - Manual Counterweight Rigging Systems

The original E1.4 is being expanded into a suite of documents to include all manually powered systems, and those rigging systems in which scenery, stage lighting, or other theatrical equipment is hung from static battens. This part of the suite applies to permanently installed, manually operated systems of stage rigging hardware for the raising, lowering, and suspension of scenery, lighting, and similar loads. It also applies to variations of manual counterweight rigging, including rope and sandbag systems.

ANSI E1.46-2016


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 by employees, but offer little guidance that is suitable for theatrical environments. This document provides that guidance to protect all people at risk. 

ANSI E1.3 - 2001 (R2016)

Entertainment Technology - Lighting Control Systems - 0 to 10 V Analog Control Specification

ANSI E1.3, Entertainment Technology - Lighting Control Systems - 0 to 10 V Analog Control Specification, describes a method of controlling equipment by means of an analog control voltage in the nominal range from zero to 10 volts positive, with the controller sourcing the signal current. This document is a reaffirmation without substantive changes of ANSI E1.3 - 2001.

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 E1.6-2-2018

Design, Inspection, and Maintenance of Electric Chain Hoists for the Entertainment Industry

ANSI E1.6-2-2018 is part of the E1.6 powered entertainment rigging suite of standards. It covers the design, inspection, and maintenance of serially manufactured electric link chain hoists having capacity of 2 tons or less and used in the entertainment industry. This standard does not cover attachment to the load or to the overhead structure. Controls used for multiple hoist operation are excluded from the scope of this part of the standard.
