Preface<\/strong><\/p>\n

<\/p>\n

This is the fourth edition of CSA C22.2 No. 0.8, Safety functions incorporating electronic technology, one of a series of Standards issued by the CSA Group under Part II of the Canadian Electrical Code. It supersedes the previous editions published in 2012, 2009, and 1986.<\/p>\n

<\/p>\n

Changes to this edition include<\/p>\n

<\/p>\n

a) update of requirements to be more general in alignment with the IEC 60730-1 series;<\/p>\n

<\/p>\n

b) use of the term define safe state for consistency with the IEC 60730-1 series;<\/p>\n

<\/p>\n

c) adjustments to definitions for consistency with IEC standards;<\/p>\n

<\/p>\n

d) addition of requirements for the security of software updates; and<\/p>\n

<\/p>\n

e) revision of requirements for clarity.<\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

1.1<\/p>\n

This Standard applies to products and component devices where the electronics technology handles the operational logic including the safety features. This Standard applies to the following configurations:<\/p>\n

<\/p>\n

a) safety control function(s) implemented in hardware only; and<\/p>\n

<\/p>\n

b) safety control function(s) implemented in some combinations of hardware and software.<\/p>\n

<\/p>\n

Note: Clauses that are identified by an asterisk define a simplified path for hardware-only designs. For reference, these clauses are listed in Table 2.<\/p>\n

<\/p>\n

1.2<\/p>\n

The scope of this Standard includes the sensors and actuators that are associated with the safety control.<\/p>\n

<\/p>\n

1.3<\/p>\n

The requirements in this Standard apply to products where failure in either the hardware or software, or any associated devices, can lead to a hazard.<\/p>\n

<\/p>\n

1.4<\/p>\n

This Standard prescribes minimum requirements for the documentation necessary to evaluate and confirm that the equipment meets the safety requirements as specified in this Standard.<\/p>\n

<\/p>\n

1.5<\/p>\n

This Standard applies to a product identified under a relevant product standard and where the purpose of the product, along with its features and operational role, can be described.<\/p>\n

<\/p>\n

Note: An understanding of the specific end-use environment and any risks associated with the product is essential for this Standard to apply.<\/p>\n

<\/p>\n

1.6<\/p>\n

This Standard does not cover general-purpose applications or products where the end-application or the safety requirements for the product are not known or cannot be described, such as for a general- purpose programmable logic controller (PLC).<\/p>\n

<\/p>\n

1.7<\/p>\n

In this Standard, 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.<\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

Notes to tables and figures are considered part of the table or figure and may be written as requirements.<\/p>\n

<\/p>\n

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.<\/p>\n","protected":false},"excerpt":{"rendered":"
