The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof. This standard also applies to electrically operated door locks for equipment that may be used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications. This standard does not apply to electrically operated door locks intended exclusively for industrial process applications unless explicitly mentioned in the equipment standard. This standard does not apply to electrically operated door locks intended for security access applications. This part 2 is intended to be used in conjunction with IEC 60730-1. It was established on the basis of the fifth edition (2013) of that publication. Consideration may be given to future editions of, or amendments to, IEC 60730-1. This third edition cancels and replaces the second edition published in 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - aligns the text with IEC 60730-1, Edition 5; - modifies requirements for Class B control function (H.27.1.2.2); - modifies requirements for Class C control function (H.27.1.2.3) and - modifies requirements for faults during safety shut-down.
