CAN/CSA-Z434-03 (R2013)

Preface

This is the second edition of CSA Z434, Industrial Robots and Robot Systems — General Safety Requirements. It supersedes the first edition published in 1994.

This Standard specifies minimum requirements for manufacture (including remanufacture and rebuilding), installation, safeguarding methods, maintenance and repair, and testing and start-up and for training of personnel in order to prevent injuries and accidents and to enhance the safety of personnel using industrial robot systems.

In developing this Standard, it was the intent of the Technical Committee to harmonize it with ANSI/RIA R15.06-1999, Industrial Robots and Robot Systems — Safety Requirements. As a result, the Technical Committee undertook an extensive review of ANSI/RIA R15.06-1999 to ensure that the requirements meet the needs of Canadian stakeholders. The Technical Committee also reviewed and considered other similar and relevant documents, including international standards, in developing this Standard.

The Technical Committee would like to acknowledge Jeff Fryman of the Robotic Industries Association for his extraordinary contributions in assisting the Technical Committee in their understanding of ANSI/RIA R15.06-1999 and for providing valuable information regarding the rationale for its requirements as prescribed. Special thanks go to the Robotic Industries Association, Ann Arbor, Michigan, for their permission to adapt the material contained in ANSI/RIA R15.06-1999 for use in CSA Z434.

This Standard was prepared by the Technical Committee on Industrial Robots and Robot Systems, under the jurisdiction of the Strategic Steering Committee on Occupational Health and Safety, and has been formally approved by the Technical Committee.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope

1.1 Scope

This safety Standard applies to the manufacture, remanufacture, rebuild, installation, safeguarding, maintenance and repair, testing and start-up, and personnel training requirements for industrial robots and robot systems.

1.2 Purpose

The purpose of this Standard is to provide requirements for industrial robot manufacture, remanufacture, and rebuild; robot system integration/installation; and safeguarding methods to enhance the safety of personnel associated with the use of robots and robot systems.

Note: As used in this Standard, the term robot or robot system is intended to mean industrial robots or industrial robot systems as defined in Clause 3.2.

1.3 Exclusions

This Standard applies to only industrial robots and robot systems. It does not apply to non-industrial robot applications such as undersea and space robots, tele-operated manipulators, prosthetics and other aids for persons with disabilities, micro-robots (displacement < 1 mm), autonomous mobile robots, surgery, and service.

1.4 Interaction with Other Standards

A robot is typically not a stand-alone device, but is integrated into an automated work cell with other machinery or devices that have Standards covering their use. Other machinery and work environment standards applicable to any workplace where this Standard is being implemented should therefore be reviewed. See Annex E for a suggested list of applicable Standards and other references.

1.5 Terminology

In CSA Standards, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Legends to equations and figures are considered requirements.

1.6 Measurements

The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
