ORDER
New Delhi, the 10th March 2025.
F. No. 8(1)/2018-HEI-Part (1). - Product Specific Guidelines for Low Voltage Switchgear and
Controlgear: Control circuit devices and switching elements – Electromechanical control circuit devices with
mechanical latching function conforming to IS/IEC 60947-5-5 : 2016 under Electrical Equipment (Quality
Control) Order, and subsequent amendments made from time to time.
1. This Product Specific Guidelines /sampling shall be used for the purpose of grant of licence /change in scope
of licence for Low Voltage Switchgear and Controlgear: Control circuit devices and switching elements –
Electromechanical control circuit devices with mechanical latching function conforming to IS/IEC 60947-5-5 : 2016
under Electrical Equipment (Quality Control) Order, 2020 and subsequent amendments made from time to time and as
per the procedure defined by Bureau of India Standards, accordingly.
2. For purpose of obtaining the licence / change in scope of licence from the Bureau, Manufacturer shall apply
to Bureau of Indian Standards ascertaining the scope of licence and technical file including test reports(s) /
certificates(s), etc. as per the procedure defined by the Bureau of Indian Standards under the Conformity Assessment
Scheme as mentioned in the Electrical Equipment (Quality Control) Order, 2020 and subsequent amendments made
from time to time ensuring the minimum number of sample(s) in respect of a product series/range or group.
3. Product Grouping
3.1 Product series of equipment(s): A group of Electrical Emergency Stop Devices with mechanical latching
function, as defined in 3.2 and 3.7 of IS/IEC 60947-5-5: 2016; referred to a particular type designation with a unique
combination of feature(s) under classification mentioned in Table A at Annexure -I.
4. Sampling and Testing
4.1 Sampling and Testing: The type test for each product series shall be as below:
4.1.1 For each product series, type test report an Electrical Emergency Stop Device with mechanical latching
function with maximum features and
configurations satisfying all operational performance criteria shall be tested. The tests and sample(s) must be in
accordance with the clause 7 of IS/IEC 60947-5-5: 2016.
Note- Spares, accessories and sub-assemblies are integral part of product series. They shall be tested as far as
possible with the equipment. (Spares and sub-assemblies being the integral part of the device, separate testing
is not envisaged; Accessories may please be used while testing.)
In case, the accessories are complying to the requirement of any other standard (IS/IEC 60947 series) then
accessories shall meet the requirements of the respective Indian Standards.
4.1.2. Each Product rating(s) / varieties may not be subjected to testing. Product samples as mentioned in para
4.1.4 will cover all the product rating(s) / varieties having ratings lower or equal under the scope of Licence is by
virtue of this grouping guidelines.
4.1.3 Three identical samples of emergency stop device shall be selected, and each sample shall be subjected
successfully to the sequence of tests, in the order given in clause 7 of IS/IEC 60947-5-5: 2016.
When more than one type of emergency stop device is manufactured to the same basic design, less than three
identical samples may be tested, providing that more than three products of the same family are tested. Such
an acceptance shall be fully documented.
4.1.4 Electrical requirements for associated contact elements as per clause 5 of IS/IEC 60947-5-5: 2016, only needs
to be tested as per IS/IEC 60947-5-1; and need not to be repeated with Emergency Stop Devices. Testing procedure
and sample selection etc. is separately defined in "Product Specific Guidelines for IS/IEC 60947-5-1" along with test
mentioned in respective Annex of IS/IEC 60947-5-1.
