maintain the required construction integrity.<\/p>\n Testing can include:<\/p>\n These requirements are reflected in BIS laboratory scopes for IS 16242 Part 1.<\/p>\n Many UPS and inverter systems incorporate batteries.<\/p>\n Battery location and related construction requirements can therefore be important during compliance evaluation.<\/p>\n BIS LIMS testing information for IS 16242 Part 1 includes Clause 7.6 \u2013 Battery Location<\/strong> among the listed testing areas.<\/p>\n UPS and inverter equipment can generate heat during operation because of power conversion, switching and electrical losses.<\/p>\n Temperature-rise testing helps evaluate whether the equipment remains within applicable safety limits under specified operating conditions.<\/p>\n BIS laboratory scopes identify Clause 7.7 \u2013 Temperature Rise<\/strong> as a testing area under IS 16242 Part 1.<\/p>\n The first step is to determine whether the UPS or inverter falls within the applicable BIS CRS product category.<\/p>\n Important information includes:<\/p>\n For the requested product category, the applicable standard is:<\/p>\n IS 16242 (Part 1):2014<\/strong><\/p>\n BIS’s compulsory-registration documentation identifies UPS\/Inverters of rating \u22645 kVA<\/strong> against this standard.<\/p>\n The manufacturer should prepare the necessary technical information before laboratory testing.<\/p>\n Documents may include:<\/p>\n Representative samples are submitted to an applicable BIS-recognized laboratory.<\/p>\n The laboratory evaluates the product against the applicable requirements of IS 16242 Part 1.<\/p>\n BIS LIMS currently lists multiple laboratories with testing scopes for this standard.<\/p>\n After testing, the laboratory prepares the applicable test report.<\/p>\n The report should accurately identify the tested product, manufacturer, brand and model.<\/p>\n Any difference between the tested product and the product proposed for registration can create compliance issues.<\/p>\n After the applicable testing and documentation are completed, the BIS CRS application can be processed with the required supporting documents and test report.<\/p>\n BIS reviews the application and supporting information under the applicable regulatory framework.<\/p>\n After successful completion of the applicable process, BIS registration can be granted subject to the relevant requirements.<\/p>\n The exact documentation depends on the product and applicant structure.<\/p>\n Common documents can include:<\/p>\n All information should remain consistent across the sample, technical documents, laboratory report and BIS application.<\/p>\n Testing is a major part of the BIS CRS registration process.<\/p>\n BIS LIMS currently lists multiple laboratories with testing facilities for IS 16242 Part 1:2014.<\/p>\n Current examples include:<\/p>\n These are examples from individual laboratory listings, not a universal BIS testing fee. Charges can vary according to laboratory, product configuration, testing scope, exclusions and applicable requirements.<\/p>\n The final testing cost can depend on:<\/p>\n Manufacturers should obtain a current quotation from the selected BIS-recognized laboratory before submitting samples.<\/p>\n Manufacturers may encounter delays because of:<\/p>\n A technical review before laboratory testing can help identify potential issues early.<\/p>\n Manufacturers should ensure that the product configuration is finalized before testing.<\/p>\n Important pre-testing checks can include:<\/p>\n The sample submitted for testing should represent the intended commercial production model.<\/p>\n Overseas manufacturers and importers supplying applicable UPS\/inverter products in India should assess BIS requirements before commercial import.<\/p>\n Where BIS CRS registration is applicable, the product should comply with the applicable Indian Standard and registration requirements.<\/p>\n Applicant, manufacturer and authorization documentation should also be prepared according to the applicable BIS framework.<\/p>\n Qualitance India can provide support with documentation, laboratory coordination and BIS CRS application assistance.<\/p>\n BIS CRS should not automatically be treated as an ISI Mark licensing process.<\/p>\n The applicable conformity assessment procedure depends on the product and scheme. Therefore, manufacturers should verify the current requirements applicable to their UPS\/inverter product rather than assuming that factory inspection is mandatory for every CRS registration.<\/p>\n Manufacturers should verify the applicable edition of the standard before beginning a new certification project.<\/p>\n The BIS Scheme-II webpage currently lists IS 16242 (Part 1)<\/strong> for UPS\/Inverters and shows product entries for both \u22645 kVA and \u226410 kVA.<\/p>\n In addition, current BIS LIMS records show laboratory scope for IS 16242 (Part 1):2025 \u2013 Uninterruptible Power Systems UPS Part 1 Safety Requirements (First Revision)<\/strong>.<\/p>\n Therefore, although this article is specifically about IS 16242 (Part 1):2014<\/strong> and the \u22645 kVA category, manufacturers planning a new application should confirm the latest BIS notification, applicable standard edition and laboratory testing requirements before testing or filing.<\/p>\n Qualitance India<\/strong> provides professional BIS CRS certification consultancy for UPS, inverters and other regulated electrical and electronic products.<\/p>\n Our services can include:<\/p>\n Our team helps manufacturers organize the certification process from initial product assessment through laboratory testing and BIS registration support.<\/p>\n The BIS compulsory-registration documentation identifies IS 16242 (Part 1):2014<\/strong> for UPS\/Inverters of rating \u22645 kVA.<\/p>\n It is titled Uninterruptible Power Systems (UPS) \u2013 Part 1: General and Safety Requirements for UPS<\/strong>.<\/p>\n Yes, the BIS compulsory-registration documentation specifically lists UPS\/Inverters of rating \u22645 kVA<\/strong> under IS 16242 Part 1:2014.<\/p>\n Testing can cover protection against shock and energy hazards, protective earthing, power isolation, overcurrent and earth faults, safety interlocks, insulation, wiring, enclosure, temperature rise, electric strength and abnormal operating conditions, among other applicable requirements.<\/p>\n Testing is an important part of the BIS CRS registration process, and BIS LIMS currently lists laboratories with testing scope for IS 16242 Part 1.<\/p>\n There is no single universal testing fee. Current BIS LIMS listings show different charges at different laboratories, with examples for \u22645 kVA ranging from approximately \u20b935,000 to \u20b91,25,000 in the listings reviewed.<\/p>\n The published laboratory charges are generally shown as excluding taxes<\/strong> in BIS LIMS. The applicable tax and final quotation should be confirmed with the laboratory.<\/p>\n Model coverage depends on the applicable BIS requirements, product construction, testing and grouping considerations. The proposed models should be assessed before application.<\/p>\n Battery-related requirements can form part of the UPS safety evaluation. The exact requirements depend on the product configuration and applicable test clauses.<\/p>\n Applicability depends on the construction and classification of the specific UPS. The product should be assessed against the applicable BIS requirements before testing.<\/p>\n The applicable applicant and authorization requirements depend on the current BIS framework.
