Subject: Guidelines for Implementation of Revised Standards IS 16046 (Part 1): 2018/
IEC 62133-1: 2017 and IS 16046 (Part 2): 2018/ IEC 62133-2: 2017 superseding
IS 16046:2015/ IEC 62133: 2012 - Secondary cells and batteries containing alkaline or
other non-acid electrolytes.
1. IS 16046:2015/IEC 62133: 2012 has been revised and published in the following two
parts:
i. IS 16046 (Part 1): 2018/ IEC 62133-1: 2017 - ‘Secondary Cells and Batteries
Containing Alkaline or Other Non-Acid Electrolytes — Safety Requirements for
Portable Sealed Secondary Cells and for Batteries Made from Them for Use in
Portable Applications Part 1 Nickel Systems’.
ii. IS 16046 (Part 2): 2018/ IEC 62133-2:2017 - ‘Secondary Cells and Batteries
Containing Alkaline or Other Non-Acid Electrolytes — Safety Requirements for
Portable Sealed Secondary Cells and for Batteries Made from Them for Use in
Portable Applications Part 2 Lithium Systems’.
2. The last date for implementation of the revised Standards is 14 March 2020 after
which the old Standard IS 16046:2015/IEC 62133: 2012 shall stand withdrawn.
3. The significant changes in the revised Standards as listed below is given for the
purpose of general guidance. Licensees/ Applicants shall ensure that the product conforms to
all the requirements, as applicable, as per the revised Standard.
IS 16046 (Part 1): 2018/ IEC 62133-1: 2017
separation of lithium systems into a separate part (i.e. Part 2)
inclusion of button cell requirements.
IS 16046 (Part 2): 2018/ IEC 62133-2: 2017

4. Considering the above changes, the additional/modified tests that are to be conducted
for changeover for the existing registered manufacturers are tabulated below.
For Nickel Systems (IS 16046 (Part 1): 2018/ IEC 62133-1: 2017)
Clause Inspection/ Test
5.2 Insulation and wiring Mechanical integrity of internal connections to be
checked where connections are through soldering
5.6 Assembly of cells into batteries Batteries shall be inspected for the following:
The battery shall have some type of safety device or
feature for charging.
Batteries that are designed for the selective
discharge of a portion of their series connected cells
shall have circuitry incorporated to prevent
operation of cells outside the limits specified by the
cell manufacturer.
7.2.4 Temperature cycling Modification in test procedure w.r.t. transition time
from step 4 to step 1 for repeat test under step 5
7.3.5 Thermal abuse (Cells) Modification in test procedure
7.3.6 Crush (Cells) Modification in test procedure w.r.t. the force
applied
8.2, 9.3 Small cell and battery safety
information
Small cell and battery packages to be inspected for
caution information
10 Packaging Packaging for button cells shall not be small enough
to fit within the limits of the ingestion gauge of
Figure 2 of IS 16046 (Part 1): 2018
For Lithium Systems (IS 16046 (Part 2): 2018/ IEC 62133-2: 2017)
Clause Test
5.2 Insulation and wiring Mechanical integrity of internal connections to be
checked where connections are through soldering
5.6.1 Assembly of cells into batteries Batteries shall be inspected for the following:
If there is more than one battery housed in a single
battery case, each battery should have protective
circuitry that can maintain the cells within their
operating regions.
Batteries that are designed for the selective
discharge of a portion of their series connected cells
shall have circuitry incorporated to prevent
operation of cells outside the limits specified by the
cell manufacturer.
Protective circuit components should be added as
appropriate and consideration given to the end-
device application. The manufacturer of the battery
should provide a safety analysis of the battery
safety circuitry with a test report including a fault
analysis of the protection circuit under both
charging and discharging conditions confirming the
compliance.
5.6.2 Design recommendation Design recommendations updated
7.3.1 External short-circuit (cell) Modification in test procedure
7.3.2 External short-circuit (battery) Modification in test procedure
7.3.4 Thermal abuse (cells) Modification in test procedure
7.3.5 Crush (cells) Modification in test procedure
7.3.6 Over-charging of battery Modification in test procedure
7.3.7 Forced discharge (cells) Modification in test procedure
7.3.8 Mechanical Tests New Tests added

5. The guidelines for implementation of the revised Standards is given below:
(i) Applications for Grant of Licence (GoL)/ requests for Change in Scope of Licence
(CSoL) already submitted in BIS shall be processed as per old version. Fresh applications
for GoL/ CSoL as per old version shall be accepted only up to 14 Feb 2020.
(ii) For GoL / CSoL Applications processed as per old version, manufacturer shall switchover
to new version on or before 14 March 2020 failing which such Application(s) for
GoL/CSoL shall be processed for closure/rejection as per norms. Beyond 14 march 2020,
no Registration shall be granted as per old version.
(iii) Fresh Applications for GoL may also be submitted as per new version.
6. Procedure for switchover
(iv) Existing manufacturers can follow either Option A or Option B given below:
Option A
(v) Existing manufacturers having Registrations as per IS 16046: 2015 shall apply for a new
Registration No. through the portal as per the applicable Indian Standard
(IS 16046: Part 1: 2018 for Ni systems/ IS 16046: Part 2: 2018 for Li systems as the case
may be) by paying the Application fee and the Annual Licence fee. In case both Ni
systems and Li systems are presently covered in the scope, two separate Applications
shall be made.
(vi) The new Applications mentioned above shall be accompanied by the minimum
documents (Form-I, Undertaking, Letter of nomination of Authorized Indian
Representative) and supplementary Test Report(s) for changeover for all the base models
covered in the Scope of Registration. The Test Report(s) shall be from any BIS approved
lab for the additional/modified requirements as per the applicable revised Standard. Copy
of corresponding Test Report (as per IS 16046: 2015) and GoR/ Inclusion letter issued
earlier shall also be submitted. The Scope of the Licence so granted shall reflect the
models for which changeover is processed with the relevant IS No. and a new
Registration No. The validity of this new Registration shall be the same as the validity of
the parent Licence as per IS 16046: 2015. All subsequent changeover requests shall be
submitted under the new Registration No. only.
(vii) Fresh CSoL requests as per IS 16046: Part 1: 2018 or IS 16046: Part 2: 2018, if any, shall
be submitted under the new Registration so granted along with all applicable fees. CSoL
requests as per IS 16046: 2015 shall be processed under the parent Registration for
IS 16046: 2015. However such requests shall be accepted only until 14 Feb 2020.
Option B
(viii) In case any manufacturer does not wish to go for a changeover, he may apply for a new
Registration directly as per the applicable Indian Standard along with complete test
reports, full documentation and all applicable fees. In such case, there shall be no linking
of validity or Scope of Licence with the old Registration.
7. Registrations as per IS 16046: 2015 may be processed for cancellation after 14 March
2020.
8. Renewal of Licence for switchover cases as per Option A
For Registrations with validity on or before 14 March 2020: Manufacturer shall make a
renewal application with all applicable fees under the old Registration No only (i.e. the
one held for IS 16046: 2015). On renewal, the validity of the parent Registration shall be
reflected in the new Registration No(s) also (i.e. the ones held for IS 16046: Part 1: 2018
or IS 16046: Part 2: 2018).
For Registrations with validity after 14 March 2020: Manufacturer shall make a renewal
application with all applicable fees under the new Registration No(s) (i.e. the ones held
for IS 16046: Part 1: 2018 or IS 16046: Part 2: 2018).
9. All Registered Manufacturers and Applicants shall take timely actions for switchover
as per the above guidelines.
10. This issues with the approval of Competent Authority.
