Adapters for household and similar electrical appliances are widely used to supply electrical power to appliances and equipment used in homes, offices, commercial establishments and other locations.<\/p>\n
Because adapters are electrical products connected to the mains supply, their electrical construction, insulation, protection against electric shock, temperature performance, mechanical strength and other safety characteristics are important considerations.<\/p>\n
The Bureau of Indian Standards (BIS) has included Adapters for Household and Similar Electrical Appliances<\/strong> under the Compulsory Registration Scheme (CRS). The current BIS Scheme-II product listing identifies the applicable CRS standard as IS 302 (Part 1):2008<\/strong>.<\/p>\n At the same time, BIS has published the seventh revision IS 302 (Part 1):2024<\/strong>, which is identical under dual numbering with IEC 60335-1:2020<\/strong>. BIS’s laboratory system also currently contains testing facilities for the 2024 edition.<\/p>\n For manufacturers and importers, understanding the distinction between the currently listed CRS requirement and the newer edition is important before starting a certification or testing project.<\/p>\n BIS CRS certification is a compulsory registration framework applicable to specified electronic and electrical products.<\/p>\n Under the current BIS Scheme-II listing, Adapters for Household and Similar Electrical Appliances<\/strong> are included with:<\/p>\n Indian Standard:<\/strong> IS 302 (Part 1):2008<\/p>\n Product:<\/strong> Adapters for household and similar electrical appliances<\/p>\n Standard Title:<\/strong> Safety of Household and Similar Electrical Appliances \u2014 Part 1 General Requirements<\/p>\n The product is listed under the Electronics and Information Technology Goods (Requirement of Compulsory Registration) Order framework.<\/p>\n There are two important editions to understand.<\/p>\n IS 302 (Part 1):2008<\/strong> is the standard currently identified for adapters in the BIS Scheme-II CRS product listing.<\/p>\n BIS’s official test report format specifically identifies:<\/p>\n Test Item:<\/strong> Adapters for household and similar electrical appliances<\/p>\n Standard:<\/strong> IS 302 (Part 1):2008<\/p>\n Test Procedure:<\/strong> Compulsory Registration Scheme.<\/p>\n BIS has subsequently published:<\/p>\n IS 302 (Part 1):2024 \/ IEC 60335-1:2020<\/strong><\/p>\n Title:<\/strong> Household and Similar Electrical Appliances \u2014 Safety Part 1 General Requirements (Seventh Revision)<\/p>\n BIS’s standard details identify the 2024 Indian Standard as identical under dual numbering with IEC 60335-1:2020.<\/p>\n BIS’s Uniform Test Report Format page also provides a test-report format for IS 302 (Part 1):2024 \/ IEC 60335-1:2020<\/strong>.<\/p>\n For website content and certification planning, it is important not to automatically state that IS 302 (Part 1):2024 has replaced IS 302 (Part 1):2008 for the CRS adapter category<\/strong>.<\/p>\n The current BIS Scheme-II page continues to list Adapters for household and similar electrical appliances against IS 302 (Part 1):2008<\/strong>.<\/p>\n Therefore, manufacturers should verify the latest applicable BIS notification, transition instructions and laboratory requirements before beginning a new application or testing under the 2024 edition.<\/p>\n An electrical adapter is a device designed to provide electrical power to an appliance or equipment from a suitable electrical supply.<\/p>\n Depending on the design, an adapter may incorporate:<\/p>\n The exact construction varies according to the appliance for which the adapter is designed.<\/p>\n The BIS CRS category covers:<\/p>\n Adapters for Household and Similar Electrical Appliances<\/strong><\/p>\n The applicability should be determined according to the actual product design, intended use, electrical ratings and applicable BIS requirements.<\/p>\n Manufacturers should provide complete technical information about the adapter before laboratory testing so that the appropriate testing scope can be established.<\/p>\n Adapters are directly associated with electrical power supply and can present safety risks if improperly designed or manufactured.<\/p>\n BIS compliance helps ensure that covered products are evaluated against the applicable Indian Standard.<\/p>\n Important safety considerations include:<\/p>\n The applicable tests depend on the standard edition and product construction.<\/p>\n Testing of adapters under the applicable standard involves multiple safety evaluations.<\/p>\n Important areas can include the following.<\/p>\n The adapter’s required product markings, ratings, warnings and instructions are evaluated.<\/p>\n The construction is evaluated to ensure that users are appropriately protected from hazardous live parts.<\/p>\n The electrical input characteristics are evaluated against the applicable requirements.<\/p>\n The product’s electrical insulation and protection against leakage and dielectric breakdown are evaluated.<\/p>\n Where applicable, the adapter is evaluated for electrical safety following the specified moisture treatment.<\/p>\n The product is evaluated under applicable abnormal operating conditions to assess safety.<\/p>\n The enclosure and relevant construction are evaluated for mechanical strength.<\/p>\n The internal and external construction is assessed against applicable requirements.<\/p>\n Internal wiring is examined for appropriate routing, protection and construction.<\/p>\n Relevant components are assessed according to the applicable requirements.<\/p>\n The supply connection and external flexible cord arrangements are evaluated.<\/p>\n Applicable terminals are evaluated for electrical and mechanical safety.<\/p>\n Where applicable, the earthing arrangement is evaluated.<\/p>\n Relevant screws and electrical\/mechanical connections are evaluated.<\/p>\n The insulation system is assessed to provide appropriate protection against electrical hazards.<\/p>\n Relevant materials and construction are evaluated against applicable heat and fire requirements.<\/p>\n Applicable metallic parts and construction are evaluated for resistance to rusting.<\/p>\n BIS laboratory records for IS 302 (Part 1) include these types of test clauses for household and similar electrical appliances.<\/p>\n The 2024 edition introduces the seventh revision of the general safety requirements and is identified by BIS as IS 302 (Part 1):2024 \/ IEC 60335-1:2020<\/strong>.<\/p>\n BIS LIMS currently shows laboratories with testing facilities for IS 302 (Part 1):2024. For example, current listings include charges such as:<\/p>\n These are laboratory-specific charges and are not a fixed BIS certification fee. The applicable testing cost depends on the laboratory, product configuration, test scope and exclusions.<\/p>\n For an adapter specifically, manufacturers should obtain confirmation from the selected BIS-recognized laboratory regarding the exact applicable edition and test scope before submitting samples.<\/p>\n BIS LIMS currently shows laboratories with testing scope specifically mentioning Adapters for household and similar electrical appliances<\/strong> under IS 302 (Part 1):2008.<\/p>\n Examples of current laboratory listings include:<\/p>\n The actual quotation can vary according to laboratory, scope, product configuration and applicable testing requirements. Taxes and additional testing, where applicable, may be charged separately.<\/p>\n Manufacturers should obtain a current quotation before finalizing the certification budget.<\/p>\n The exact documents depend on the manufacturer, product and certification scope. Commonly required documents may include:<\/p>\n The final document requirement should be confirmed according to the current BIS application procedure.<\/p>\n The adapter is reviewed to determine its applicable BIS category, electrical characteristics and intended use.<\/p>\n The applicable edition of IS 302 (Part 1) is confirmed against the current BIS CRS requirements and any applicable transition instructions.<\/p>\n The manufacturer identifies the models and variants intended for certification.<\/p>\n Product specifications, circuit diagrams, labels and other required documents are prepared.<\/p>\n A BIS-recognized laboratory with the relevant scope is selected.<\/p>\n Representative adapter samples are submitted for testing.<\/p>\n The laboratory conducts the applicable tests under the relevant standard.<\/p>\n After successful testing, the applicable laboratory test report is issued.<\/p>\n The manufacturer submits the CRS application along with the required documentation and test report.<\/p>\n BIS reviews the application and supporting documents.<\/p>\n If BIS raises observations or requests additional information, the applicant provides the required response.<\/p>\n After successful completion of the applicable requirements, BIS CRS registration is processed.<\/p>\n BIS CRS registration should not automatically be treated as identical to the traditional BIS ISI Mark licensing process.<\/p>\n For adapters under CRS, the applicable product testing, documentation and registration requirements need to be followed according to the current BIS scheme.<\/p>\n Manufacturers should therefore verify the latest BIS requirements applicable to their product instead of assuming that a traditional factory inspection procedure applies to every CRS application.<\/p>\n Foreign manufacturers supplying adapters to India should review BIS requirements before commercial import and sale.<\/p>\n Overseas manufacturers may need to provide:<\/p>\n Starting the compliance process before shipment can help avoid delays related to testing and documentation.<\/p>\n Manufacturers should ensure that product labels and markings are consistent with the applicable BIS requirements.<\/p>\n Depending on the applicable requirements, information may include:<\/p>\n The exact marking requirements should be confirmed against the applicable standard and current CRS instructions.<\/p>\n Manufacturers can face testing or certification issues due to technical and documentation inconsistencies.<\/p>\n Common problems may include:<\/p>\n A technical review before laboratory submission can help identify potential problems.<\/p>\n An adapter manufacturer may have multiple models with different:<\/p>\n Manufacturers should evaluate these differences before testing to determine the appropriate certification scope.<\/p>\n Model grouping should not be assumed solely because two adapters have similar external appearance.<\/p>\n The safety of an adapter depends on the interaction of multiple components.<\/p>\n Important construction elements may include:<\/p>\n Changes to safety-critical components can affect the conformity of the finished product and should be evaluated before implementation.<\/p>\n IS 302 (Part 1):2008 is the sixth-revision general safety standard and remains the standard currently shown against adapters on the BIS Scheme-II CRS listing.<\/p>\n IS 302 (Part 1):2024 is the seventh revision and is identical under dual numbering with IEC 60335-1:2020. BIS has already made testing arrangements available for the 2024 edition in its laboratory system.<\/p>\n Therefore, manufacturers should distinguish between:<\/p>\n Current CRS product listing:<\/strong> Latest general standard edition:<\/strong> Before starting a new certification project, the manufacturer should verify whether BIS has issued any applicable transition notification or revised product-specific requirement.<\/p>\n Qualitance India<\/strong> provides BIS certification consultancy support for manufacturers and importers of electrical and electronic products.<\/p>\n For Adapters for Household and Similar Electrical Appliances<\/strong>, our support can include:<\/p>\n Our objective is to help manufacturers understand the applicable requirements and coordinate the certification process efficiently.<\/p>\n Adapters for household and similar electrical appliances are included in the BIS CRS Scheme-II product listing. The current BIS listing identifies IS 302 (Part 1):2008<\/strong> for this product category.<\/p>\n The current CRS listing identifies IS 302 (Part 1):2008<\/strong> for adapters for household and similar electrical appliances.<\/p>\n IS 302 (Part 1):2024 is the seventh revision of the general safety requirements for household and similar electrical appliances and is identical under dual numbering with IEC 60335-1:2020.<\/p>\n The current BIS Scheme-II page continues to list adapters against IS 302 (Part 1):2008<\/strong>. Therefore, manufacturers should verify the applicable BIS transition requirements before assuming that the 2024 edition has replaced the CRS requirement for adapters.<\/p>\n BIS LIMS currently lists laboratories with testing facilities for IS 302 (Part 1):2024. However, the applicable edition for a specific CRS application should be confirmed with BIS\/current product requirements before testing.<\/p>\n Testing can include marking and instructions, protection against live parts, power input, current input, leakage current, electric strength, moisture resistance, abnormal operation, mechanical strength, construction, internal wiring, components, supply connections, terminals, earthing, creepage and clearance, resistance to heat and fire and other applicable requirements.<\/p>\n Current BIS LIMS listings show different charges depending on the laboratory and scope. Examples for adapter testing under IS 302 (Part 1):2008 include approximately \u20b915,000, \u20b950,000 and \u20b963,500 at different laboratories.<\/p>\n No. Laboratory charges vary according to the laboratory, test scope, product configuration and applicable requirements.<\/p>\n Yes, covered products supplied by overseas manufacturers can be subject to the applicable BIS CRS requirements. The overseas manufacturer should complete the applicable process before commercial supply.<\/p>\n The applicability of separate certification depends on the product’s actual classification and the applicable BIS\/QCO requirements. Each separately regulated product should be assessed independently.<\/p>\n CRS should not automatically be equated with the traditional ISI Mark licensing process. The applicable requirements should be checked under the current CRS framework.<\/p>\n Documents may include company details, manufacturing information, product specifications, circuit diagrams, component information, electrical ratings, labels, photographs, manuals, test documents and authorization documents where applicable.<\/p>\n Model coverage depends on the applicable BIS requirements and technical similarity of the products. Models should be assessed before testing.<\/p>\n The reason for failure should be identified and corrective action should be taken. Retesting may be necessary depending on the failure and applicable procedure.<\/p>\n Changes to safety-critical components or construction can affect conformity. Such changes should be evaluated before implementation.<\/p>\n The applicable BIS marking and registration requirements should be followed according to the current CRS rules and approved certification scope.<\/p>\n Yes. Qualitance India can provide testing laboratory coordination and certification consultancy support.<\/p>\n The timeline depends on laboratory availability, testing duration, documentation readiness, BIS scrutiny and whether clarification or corrective action is required.<\/p>\n IEC 60335-1:2020 is the international standard corresponding to IS 302 (Part 1):2024<\/strong>, which BIS identifies as identical under dual numbering.<\/p>\n Start with a technical product assessment and confirmation of the currently applicable BIS standard edition. The model, electrical ratings, construction and intended use should be reviewed before laboratory testing.<\/p>\nWhat Is BIS CRS Certification for Adapters?<\/h2>\n
