Introduction: BIS Certification for Ether in India<\/h2>\n

Ether is a chemical product used in industrial, laboratory, pharmaceutical and other specialised applications. Depending on its grade, it may be used as a solvent or for anaesthetic applications. Because ether is highly volatile and flammable, manufacturers must pay particular attention to product quality, testing, safe handling, packaging and applicable regulatory requirements.<\/p>\n

In India, Ether is covered under the Ether (Quality Control) Order, 2020<\/strong>, notified by the Department of Chemicals and Petrochemicals under the Ministry of Chemicals and Fertilizers. The order requires covered products to conform to the applicable Indian Standard and bear the BIS Standard Mark under a valid licence, subject to the order’s provisions and exemptions. <Cite refs={[“turn520834search42″,”turn520834search6”]}\/><\/p>\n

An important point for manufacturers is that the original Quality Control Order and the government\u2019s online listing refer to IS 336:1973<\/strong>, while BIS has issued a product manual and granted a licence under IS 336:2021 \u2013 Ether: Specification<\/strong>. Manufacturers should therefore confirm the current applicable standard and regulatory position before filing an application. <Cite refs={[“turn379506view0″,”turn379506view2″,”turn379506view3”]}\/><\/p>\n

Qualitance India provides BIS certification consultancy to help chemical manufacturers understand the applicable requirements, prepare technical documentation, coordinate product testing and navigate the BIS licensing process.<\/p>\n

1. What Is Ether?<\/h2>\n

Ether is a chemical compound used in different industrial and specialised applications. The product standard identifies two grades of ether for certification purposes:<\/p>\n

    \n
  • Solvent grade<\/strong><\/li>\n
  • Anaesthetic grade<\/strong><\/li>\n<\/ul>\n

    The manufacturer must declare the grade intended to be covered under the licence. BIS requires samples of each proposed grade to be tested for consideration of the licence or inclusion of that grade in the existing licence scope. <Cite refs={[“turn379506view0”]}\/><\/p>\n

    The intended application, grade, manufacturing process and product specifications should be clearly identified before initiating certification.<\/p>\n

    2. Applicable Indian Standard for Ether Certification<\/h2>\n

    The key standard and regulatory references are summarised below.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

    Quality Control Order<\/td>\nEther (Quality Control) Order, 2020<\/td>\n<\/tr>\n
    Regulatory authority<\/td>\nBureau of Indian Standards (BIS)<\/td>\n<\/tr>\n
    Department responsible for the QCO<\/td>\nDepartment of Chemicals and Petrochemicals<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    The BIS Product Manual PM\/IS 336\/1, dated October 2023, specifies the certification requirements according to IS 336:2021. BIS also announced the grant of an All India First Licence under IS 336:2021 on 14 November 2023. <Cite refs={[“turn379506view0″,”turn379506view3”]}\/><\/p>\n

    Important clarification about IS 336:1973<\/h3>\n

    The government\u2019s online petrochemicals QCO listing continues to display IS 336:1973, while the BIS Product Manual covers IS 336:2021. These references should not be treated as interchangeable without verification.<\/p>\n

    Before applying, manufacturers should confirm the current standard edition, applicable amendments and the implementation of any revision under the Ether Quality Control Order with BIS or the relevant regulatory authority.<\/p>\n

    3. Is BIS Certification Mandatory for Ether?<\/h2>\n

    The Ether (Quality Control) Order, 2020 requires the products covered by the order to conform to the corresponding Indian Standard and bear the Standard Mark under a BIS licence in accordance with Scheme-I of the BIS (Conformity Assessment) Regulations, 2018. The order excludes goods or articles meant for export from its application. <Cite refs={[“turn520834search42”]}\/><\/p>\n

    The Department of Chemicals and Petrochemicals lists the Ether QCO with its original notification and subsequent amendments. The government\u2019s implementation listing records 25 December 2021 as the enforcement date following amendments. <Cite refs={[“turn379506view2″,”turn520834search11”]}\/><\/p>\n

    Businesses should assess the following before manufacturing, importing, distributing or selling ether in India:<\/p>\n

      \n
    • Whether the product falls within the scope of the applicable standard and QCO.<\/li>\n
    • Which edition of IS 336 applies to the proposed certification.<\/li>\n
    • Whether the intended grade is solvent or anaesthetic.<\/li>\n
    • Whether a specific exemption applies to the product or transaction.<\/li>\n
    • Whether the manufacturing facility and testing arrangements meet the applicable BIS requirements.<\/li>\n<\/ul>\n

      Manufacturers should not assume that certification is optional simply because the product is supplied to another business or sold for industrial use.<\/p>\n

      4. Grades of Ether Covered Under BIS Certification<\/h2>\n

      The BIS Product Manual for IS 336:2021 identifies two grades: solvent and anaesthetic. The manufacturer must declare which grade or grades it intends to include in the licence scope. Samples of each grade must be drawn and tested for grant of licence or inclusion of the grade. <Cite refs={[“turn379506view0”]}\/><\/p>\n\n\n\n\n\n\n
      Grade<\/th>\nCertification consideration<\/th>\n<\/tr>\n
      Solvent grade<\/td>\nThe manufacturer must demonstrate conformity with the applicable specification for this grade.<\/td>\n<\/tr>\n
      Anaesthetic grade<\/td>\nThe manufacturer must demonstrate conformity with the applicable specification for this grade.<\/td>\n<\/tr>\n
      Both grades<\/td>\nEach proposed grade must be addressed in the testing and licence-scope assessment.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

      The manufacturer should identify all intended grades at the outset. The final scope of the BIS licence depends on the applicable standard, testing results and BIS assessment.<\/p>\n

      5. Key Quality and Testing Requirements Under IS 336:2021<\/h2>\n

      The BIS Product Manual identifies several tests and related equipment for evaluating ether. The exact acceptance limits and methods must be taken from the applicable edition of IS 336 and its amendments.<\/p>\n

      Key parameters identified in the product manual include:<\/p>\n

      A. Description and odour<\/h3>\n

      The product is examined for the specified description and odour characteristics.<\/p>\n

      B. Solubility<\/h3>\n

      Solubility is evaluated using the reagents and method prescribed in the standard.<\/p>\n

      C. Relative density<\/h3>\n

      Relative density is determined using the specified apparatus and temperature conditions.<\/p>\n

      D. Peroxides<\/h3>\n

      The product is tested for peroxides in accordance with the prescribed test method.<\/p>\n

      E. Distillation range<\/h3>\n

      The distillation range is evaluated using the specified distillation apparatus and relevant measurement equipment.<\/p>\n

      F. Residue on evaporation<\/h3>\n

      The product is assessed for residue remaining after evaporation using the prescribed method.<\/p>\n

      G. Methyl alcohol<\/h3>\n

      The standard includes a test for methyl alcohol.<\/p>\n

      H. Aldehydes and acetone<\/h3>\n

      The applicable testing programme includes checks for aldehydes and acetone.<\/p>\n

      I. Sulphurous acid and other free acids<\/h3>\n

      The product is evaluated for the specified acidic impurities. <Cite refs={[“turn379506view0”]}\/><\/p>\n

      Manufacturers should establish a testing plan that covers every applicable requirement. A product should not be considered compliant solely on the basis of a supplier certificate or a limited set of routine tests.<\/p>\n

      6. BIS Sample Quantity for Ether<\/h2>\n

      According to the BIS Product Manual PM\/IS 336\/1, the specified sample quantity is one litre<\/strong>. <Cite refs={[“turn379506view0”]}\/><\/p>\n\n\n\n\n\n\n\n\n
      Requirement<\/th>\nDetails<\/th>\n<\/tr>\n

      Additional requirement<\/td>\nConfirm sampling, packaging and dispatch instructions before sending the sample<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

      The manufacturer should confirm the current sampling procedure and dispatch instructions with the relevant BIS office or laboratory before submitting the sample.<\/p>\n

      Because ether is volatile and highly flammable, the sample must be handled, packed, labelled and transported in accordance with applicable safety requirements. Use an authorised and suitably equipped facility for sampling and testing.<\/p>\n

      7. Documents Required for BIS Certification of Ether<\/h2>\n

      A successful application requires accurate business, manufacturing, technical and quality-control information. The final document checklist should be prepared against the latest BIS application requirements and the applicable product manual.<\/p>\n
