Domestic LPG gas stoves are among the most widely used cooking appliances in Indian households. Their safety, thermal efficiency, flame stability and reliable operation are essential for protecting consumers and ensuring efficient use of liquefied petroleum gas.<\/p>\n
To ensure product quality and consumer safety, the Government of India has made BIS certification compulsory for domestic gas stoves intended for use with LPG.<\/p>\n
The product was previously covered under IS 4246:2002 \u2013 Domestic Gas Stoves for Use with Liquefied Petroleum Gases<\/strong>. However, BIS revised the standard in 2025.<\/p>\n The current applicable Indian Standard is:<\/p>\n IS 4246:2025 \u2013 Domestic Gas Stove and Built In Hob for Use With LPG<\/strong><\/p>\n The revised standard introduces updated requirements for domestic gas stoves and built-in hobs, including construction, thermal shock resistance, pan support, gas inlet connections and performance testing.<\/p>\n Manufacturers supplying covered LPG gas stoves in India must obtain the applicable BIS licence under Scheme-I of the BIS (Conformity Assessment) Regulations, 2018.<\/p>\n This article explains the mandatory certification requirements, revised standard, product classification, testing, sampling, laboratory requirements, documents and BIS certification procedure.<\/p>\n Yes. BIS certification is mandatory for domestic gas stoves covered under the applicable Quality Control Order.<\/strong><\/p>\n The Government of India notified the Domestic Gas Stoves for Use with Liquefied Petroleum Gases (Quality Control) Order, 2019<\/strong>, through S.O. 4345(E), dated 3 December 2019.<\/p>\n The Order came into force on 1 June 2020.<\/p>\n It requires covered domestic LPG gas stoves to conform to the applicable Indian Standard and bear the BIS Standard Mark under a licence issued by BIS.<\/p>\n The Order excludes goods or articles meant for export, as provided in the notification.<\/p>\n BIS issued implementation guidelines on 8 August 2025 for the revised standard.<\/p>\n The implementation deadline was 17 December 2025<\/strong>.<\/p>\n BIS directed that:<\/p>\n Therefore, manufacturers applying for BIS certification in 2026 should prepare their products and documentation according to IS 4246:2025.<\/p>\n BIS has issued the revised product manual:<\/p>\n PM\/IS 4246\/5\/August 2025<\/strong><\/p>\n This manual replaces the earlier product manual arrangements for IS 4246:2002.<\/p>\n The revised manual includes updates to:<\/p>\n Manufacturers should use the August 2025 product manual and the latest amendments or subsequent revisions, if any, when preparing their application.<\/p>\n The standard covers domestic cooking appliances intended for use with LPG, subject to the detailed scope of IS 4246:2025.<\/p>\n These are conventional domestic LPG gas stoves manufactured with metallic bodies.<\/p>\n Common market configurations include:<\/p>\n These gas stoves use a glass cooking surface supported by the relevant frame and construction.<\/p>\n The revised standard expands the scope to include metallic or plastic frames with glass tops.<\/p>\n Built-in hobs are cooking appliances designed for installation within a kitchen countertop or other suitable supporting structure.<\/p>\n IS 4246:2025 specifically incorporates requirements and test methods for built-in hobs.<\/p>\n The manufacturer must ensure that each product variety proposed for certification falls within the applicable scope of the revised standard.<\/p>\n BIS issued implementation guidelines identifying the significant changes introduced through the revision.<\/p>\n The revised standard includes built-in hobs and introduces applicable test requirements for these products.<\/p>\n This is particularly relevant for manufacturers of modern modular kitchen appliances.<\/p>\n The thermal shock test method has been modified.<\/p>\n Manufacturers of glass-top gas stoves and built-in hobs should verify that their glass components meet the revised requirements.<\/p>\n The revised standard introduces a requirement that the pan support assembly remain stable when used with flat vessels having diameters from 150 mm to 250 mm.<\/p>\n New requirements have been introduced relating to the material, position and threads of gas inlet connections.<\/p>\n A correction factor has been introduced in the gas consumption test.<\/p>\n Manufacturers must follow the revised method when assessing product performance.<\/p>\n IS 4246 establishes construction, operational, performance and safety requirements for domestic LPG gas stoves.<\/p>\n The principal technical requirements include:<\/p>\n The stove must be manufactured using suitable materials and components conforming to the applicable requirements.<\/p>\n Important components include:<\/p>\n The stove must be designed and manufactured to ensure:<\/p>\n Thermal efficiency is an important performance characteristic.<\/p>\n The earlier IS 4246:2002 requirements specified a minimum thermal efficiency of 68%.<\/p>\n Manufacturers must confirm the applicable thermal efficiency requirement and test method under IS 4246:2025 rather than relying solely on the earlier edition.<\/p>\n The burners must operate safely under the specified conditions without unacceptable flame instability.<\/p>\n The stove must demonstrate suitable flame performance when exposed to the specified draught conditions.<\/p>\n The stove must satisfy the applicable flashback requirements.<\/p>\n The appliance must meet the requirements relating to soot formation during operation.<\/p>\n Gas consumption must be determined according to the applicable test method.<\/p>\n IS 4246:2025 introduces a correction factor in this test.<\/p>\n The stove must satisfy the applicable requirements relating to fire hazards and temperature rise during operation.<\/p>\n For glass-top stoves and relevant built-in hobs, the applicable glass-related requirements must be satisfied, including the revised thermal shock provisions.<\/p>\n Testing is a critical stage of BIS certification for domestic LPG gas stoves.<\/p>\n The following table summarises the principal areas of testing associated with IS 4246.<\/p>\n The exact test programme, clause references and acceptance criteria must be taken from IS 4246:2025 and its applicable product manual.<\/p>\n Not every test necessarily applies to every construction or product configuration.<\/p>\n Under the earlier BIS Product Manual PM\/IS 4246\/2\/May 2019 for IS 4246:2002, the specified sample quantity was:<\/p>\n One complete gas stove.<\/strong><\/p>\n The earlier manual also required each type of domestic gas stove to be tested for grant or change in scope of licence.<\/p>\n However, BIS revised the product manual in August 2025.<\/p>\n For applications under IS 4246:2025, manufacturers should verify the sample quantity and grouping requirements in PM\/IS 4246\/5\/August 2025<\/strong>.<\/p>\n The earlier one-stove requirement should not automatically be treated as the current sampling rule for every stove or built-in hob configuration.<\/p>\n Product grouping determines which models must be tested and which varieties may be covered under a BIS licence.<\/p>\n For domestic LPG gas stoves, relevant considerations may include:<\/p>\n The earlier BIS product manual required each type of domestic gas stove to be tested for grant of licence or change in scope.<\/p>\n The revised standard includes built-in hobs and additional construction types.<\/p>\n Therefore, manufacturers should assess the proposed model range according to the current product manual and licence-scope provisions.<\/p>\n A manufacturer producing the following products should prepare a model-wise scope assessment:<\/p>\n The number of samples required for these models must be determined according to the current BIS grouping guidelines.<\/p>\n A model-wise grouping assessment before application can help avoid unnecessary testing and licence-scope issues.<\/p>\n Manufacturers must establish suitable testing and quality-control arrangements for domestic LPG gas stoves.<\/p>\n The required facilities depend on the applicable tests and the manufacturer’s product range.<\/p>\n This is an indicative planning list, not a substitute for the test equipment schedule in the current BIS product manual.<\/p>\n The manufacturer should ensure that:<\/p>\n Whether a particular test may be subcontracted must be confirmed from the current product manual and applicable BIS instructions.<\/p>\n The manufacturer must implement the Scheme of Inspection and Testing applicable to IS 4246:2025.<\/p>\n The SIT establishes the production inspection and testing arrangements required to ensure consistent product conformity.<\/p>\n Incoming Material Inspection<\/strong><\/p>\n The manufacturer should verify the quality and conformity of relevant materials and components.<\/p>\n In-process Inspection<\/strong><\/p>\n Inspection should be carried out during burner assembly, gas tap fitting, body assembly and other manufacturing stages.<\/p>\n Finished Product Inspection<\/strong><\/p>\n Completed stoves should be checked for applicable construction, workmanship, safety and performance requirements.<\/p>\n Routine Testing<\/strong><\/p>\n Routine tests must be carried out at the frequency specified in the current SIT.<\/p>\n Calibration<\/strong><\/p>\n Testing and measuring equipment must be calibrated according to the applicable calibration plan.<\/p>\n Test Records<\/strong><\/p>\n The manufacturer must maintain appropriate records demonstrating conformity of the production covered by the BIS licence.<\/p>\n Non-Conforming Products<\/strong><\/p>\n A documented procedure should be established for identifying, segregating and controlling products that do not meet the standard.<\/p>\n The actual control units, sample quantities and test frequencies must be taken from the current SIT.<\/p>\n After obtaining the BIS licence, the manufacturer must mark conforming products in accordance with the applicable Indian Standard and BIS licence conditions.<\/p>\n The marking arrangements generally involve:<\/p>\n Manufacturers must ensure that the Standard Mark is applied only to products covered by the valid licence and conforming to the applicable requirements.<\/p>\n The manufacturer should provide installation, operation and safety instructions as required by the current standard.<\/p>\n These may include guidance relating to:<\/p>\n The exact marking and instruction requirements must be verified against IS 4246:2025.<\/p>\n Manufacturers should prepare the following documents before submitting the BIS application.<\/p>\n The final documentation depends on the product type, manufacturing arrangements and current BIS requirements.<\/p>\n The total cost of BIS certification depends on several factors.<\/p>\n These include:<\/p>\n1.
