CAN/CSA-C22.2 No. 61730-2:11
Photovoltaic (PV) module safety qualification — Part 2: Requirements for testing
This National Standard of Canada is based on International Standard IEC 61730-2:2004.
1 Scope and object
This part of IEC 61730 describes the testing requirements for photovoltaic (PV) modules in
order to provide safe electrical and mechanical operation during their expected lifetime.
Specific topics are provided to assess the prevention of electrical shock, fire hazards, and
personal injury due to mechanical and environmental stresses. IEC 61730-1 pertains to the
particular requirements of construction. This part of IEC 61730 outlines the requirements of
This standard attempts to define the basic requirements for various application classes of
photovoltaic modules, but it cannot be considered to encompass all national or regional
building codes. The specific requirements for marine and vehicle applications are not covered.
This standard is not applicable to modules with integrated AC inverters (AC modules).
This standard is designed so that its test sequence can co-ordinate with those of IEC 61215
or IEC 61646, so that a single set of samples may be used to perform both the safety and
performance evaluation of a photovoltaic module design.
The test-sequences of this standard are arranged in an optimal way so that tests of
IEC 61215 or IEC 61646 can be used as basic preconditioning tests.
NOTE 1 The sequence of tests required in this standard may not test for all possible safety aspects associated
with the use of PV modules in all possible applications. This standard utilizes the best sequence of tests available
at the time of its writing. There are some issues, such as the potential danger of electric shock posed by a broken
module in a high voltage system, that should be addressed by the systems design, location, restrictions on access
and maintenance procedures.
The object of this document is to provide the testing sequence intended to verify the safety of
PV modules whose construction has been assessed by IEC 61730-1. The test sequence and
pass criteria are designed to detect the potential breakdown of internal and external
components of PV modules that would result in fire, electric shock and personal injury. The
standard defines the basic safety test requirements and additional tests that are a function of
the module end-use applications.
Test categories include general inspection, electrical shock hazard, fire hazard, mechanical
stress, and environmental stress.
NOTE 2 The additional testing requirements outlined in relevant ISO standards, or the national or local codes
which govern the installation and use of these modules in their intended locations, should be considered in addition
to the requirements contained within this document.
