1 Scope This part of IEC 61730 specifies and describes the fundamental construction requirements for photovoltaic (PV) modules in order to provide safe electrical and mechanical operation. Specific topics are provided to assess the prevention of electrical shock, fire hazards, and personal injury due to mechanical and environmental stresses. This part of IEC 61730 pertains to the particular…

1 Scope The scope of IEC 61730-1 is also applicable to this part of IEC 61730. While IEC 61730-1 outlines the requirements of construction, this part of the standard lists the tests a PV module is required to fulfill for safety qualification. IEC 61730-2 is applied for safety qualification only in conjunction with IEC 61730-1. The sequence of tests required in this standard may not test for…

1 Scope 1.1 This Standard applies to newly produced gas selector devices (see Clause 3), herein after referred to as a “device”, constructed entirely of new, unused parts and materials. 1.2 The device may include functions such as selection of type of gas to operate the appliance and main burner primary air adjustment. The device may also contain multiple passageways that can be selected to…

1 Scope 1.1 This Standard establishes steady-state voltage operating ranges at point of connection for AC power systems in Canada. It serves to provide guidance a) to national committees on utilization and control equipment for establishing standard ratings of such equipment on a basis coordinated with power system voltages; b) to power system designers so that new systems will be designed…

1 Scope This National Standard of Canada (NSC) addresses requirements for radon control in the design and construction of new, low-rise residential buildings (see Definitions). This Standard provides design criteria, design tools, methods and techniques, and sample construction specifications to minimize radon entry into new homes prior to initial occupancy and prepare for future mitigation…

IEC 60335-2-97:2016+A1:2019 deals with the safety of electric drives for shutters, blinds and awnings, intended for household and similar purposes, their rated voltage being not more than 250 V for single-phase drives and 480 V for other drives. Battery-operated drives and other d.c. supplied drives are within the scope of this standard. Examples of equipment that can be driven are: - spring…

IEC 60335-2-103:2015+A1:2017+A2:2019 deals with the safety of electric drives for horizontally and vertically moving gates, doors, garage doors and windows for household and similar purposes, their rated voltage being not more than 250 V for single-phase drives and 480 V for other drives. It also covers the hazards associated with the movement of the driven part. Battery-operated drives and…

This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve. For other size fractions, a recommended method is described in Annex A. The aggregate…

1 Scope 1.1 This Standard covers commercial and industrial plant oil extraction equipment for installation and use indoors in an ordinary (unclassified) locations and hazardous (classified) locations. Based on the application, installation is in accordance with the manufacturer's installation instructions, together with the following, as applicable: a) CSA C22.1, Canadian Electrical…

IEC 60335-2-116:2019 deals with the safety of furniture with electrically motorized parts intended for household and similar purposes, their rated voltage being not more than 250 V. Furniture incorporating electrically motorised parts not intended for normal household use but which nevertheless may be a source of danger to the public, such as furniture intended to be used by laymen in shops,…
