Introduction<\/h2>\n

Polypropylene fibre ropes are widely used in marine operations, agriculture, construction, transportation, fishing, logistics, industrial applications and other general-purpose uses. Their performance depends on factors such as the polypropylene material, rope construction, linear density, diameter and minimum breaking strength.<\/p>\n

To establish conformity of specified polypropylene fibre ropes with Indian requirements, IS 5175:2022<\/strong> provides the applicable technical requirements.<\/p>\n

The standard is titled Fibre Ropes \u2013 Polypropylene Split Film, Monofilament and Multifilament (PP2) and Polypropylene High-Tenacity Multifilament (PP3) \u2013 3-, 4-, 8- and 12-Strand Ropes<\/strong>. It is aligned with ISO 1346:2021<\/strong>.<\/p>\n

The product is also covered under the Ropes and Cordages (Quality Control) Order, 2024<\/strong>, under which the specified goods must conform to the corresponding Indian Standard and bear the Standard Mark under a BIS licence in accordance with Scheme-I. The QCO came into force on 1 April 2025<\/strong>, with a separate commencement date of 1 July 2025 for Small and Micro Enterprises for domestic production<\/strong>. The Order does not apply to goods meant for export.<\/p>\n

For manufacturers, exporters, importers and overseas companies supplying these ropes to India, understanding the BIS certification requirements before commercial production or import is therefore important.<\/p>\n

What is IS 5175:2022?<\/h2>\n

IS 5175:2022<\/strong> is the fourth revision of the Indian Standard for specified polypropylene fibre ropes.<\/p>\n

The standard covers ropes made from:<\/p>\n

    \n
  • Polypropylene split film<\/li>\n
  • Polypropylene monofilament<\/li>\n
  • Polypropylene multifilament<\/li>\n
  • Polypropylene high-tenacity multifilament<\/li>\n<\/ul>\n

    The standard identifies PP2<\/strong> and PP3<\/strong> material categories and covers four principal rope constructions:<\/p>\n

      \n
    • Type A \u2013 3-strand hawser-laid rope<\/strong><\/li>\n
    • Type B \u2013 4-strand shroud-laid rope<\/strong><\/li>\n
    • Type L \u2013 8-strand braided rope<\/strong><\/li>\n
    • Type T \u2013 12-strand braided rope<\/strong><\/li>\n<\/ul>\n

      It also specifies requirements relating to designation, general requirements, linear density and minimum breaking strength.<\/p>\n

      Is BIS Certification Mandatory for Polypropylene Fibre Ropes?<\/h2>\n

      Yes, specified polypropylene fibre ropes are covered under the Ropes and Cordages (Quality Control) Order, 2024<\/strong>.<\/p>\n

      The QCO includes Fibre ropes \u2013 Polypropylene split film, monofilament and multifilament (PP2) and polypropylene high-tenacity multifilament (PP3) \u2013 3-, 4-, 8- and 12-strand ropes<\/strong>, corresponding to IS 5175:2022<\/strong>. The QCO requires conformity to the Indian Standard and the use of the Standard Mark under a BIS licence under Scheme-I.<\/p>\n

      Implementation Dates<\/h3>\n

      For the Ropes and Cordages QCO:<\/p>\n

        \n
      • 1 April 2025:<\/strong> General commencement.<\/li>\n
      • 1 July 2025:<\/strong> Commencement for Small and Micro Enterprises for domestic production.<\/li>\n<\/ul>\n

        These dates are specified in the 2024 QCO.<\/p>\n

        A later amendment issued on 5 June 2026<\/strong> created a temporary exemption concerning goods specified at serial number 7 that are made out of recycled plastic waste, for twelve months from publication of that amendment. Manufacturers dealing with such products should verify the precise applicability of this exemption before relying on it.<\/p>\n

        What Does the BIS ISI Mark Mean for Polypropylene Ropes?<\/h2>\n

        The BIS Standard Mark, commonly referred to as the ISI Mark<\/strong>, is used under a valid BIS licence and indicates conformity with the applicable Indian Standard within the approved certification scope.<\/p>\n

        For covered polypropylene fibre ropes, manufacturers should not treat the ISI Mark as a general quality logo. The product must be covered by an appropriate BIS licence, and the marking must comply with the licence conditions.<\/p>\n

        The BIS Scheme-I listing currently includes IS 5175:2022<\/strong> under Ropes and Cordages compulsory certification.<\/p>\n

        Which Polypropylene Ropes Are Covered?<\/h2>\n

        IS 5175:2022 covers the specified polypropylene fibre ropes manufactured using PP2 and PP3 materials and four strand constructions.<\/p>\n

        3-Strand Polypropylene Rope<\/h3>\n

        Type A is a 3-strand hawser-laid rope<\/strong>.<\/p>\n

        4-Strand Polypropylene Rope<\/h3>\n

        Type B is a 4-strand shroud-laid rope<\/strong>.<\/p>\n

        8-Strand Polypropylene Rope<\/h3>\n

        Type L is an 8-strand braided rope<\/strong>.<\/p>\n

        12-Strand Polypropylene Rope<\/h3>\n

        Type T is a 12-strand braided rope<\/strong>.<\/p>\n

        These four constructions are expressly identified in the BIS Product Manual and current BIS laboratory scope.<\/p>\n

        PP2 and PP3 Polypropylene Fibre Ropes<\/h2>\n

        The standard distinguishes between different polypropylene material categories.<\/p>\n

        PP2<\/strong> covers polypropylene split film, monofilament and multifilament rope materials.<\/p>\n

        PP3<\/strong> covers polypropylene high-tenacity multifilament.<\/p>\n

        The applicable material category should be correctly identified before testing and preparation of the BIS certification scope.<\/p>\n

        A manufacturer should not assume that certification for one material category automatically covers every other polypropylene material category.<\/p>\n

        Rope Types Under IS 5175:2022<\/h2>\n

        The BIS Product Manual identifies the licence scope using Type A\/B\/L\/T<\/strong>, corresponding to the four constructions. It also identifies size using the applicable reference number<\/strong>, which corresponds approximately to rope diameter. The material and termination configuration are also relevant to the licence scope.<\/p>\n

        Therefore, manufacturers should prepare their product range carefully before beginning testing.<\/p>\n

        Unspliced and Eye-Spliced Polypropylene Ropes<\/h2>\n

        The BIS Product Manual identifies both:<\/p>\n

          \n
        • Unspliced ropes<\/li>\n
        • Ropes with eye-spliced terminations<\/li>\n<\/ul>\n

          as relevant scope parameters.<\/p>\n

          The proposed licence scope should therefore clearly identify which varieties the manufacturer intends to cover.<\/p>\n

          Key Requirements Under IS 5175:2022<\/h2>\n

          The standard addresses several important characteristics of polypropylene fibre ropes.<\/p>\n

          General Requirements<\/h3>\n

          The rope must comply with the applicable general requirements relating to its construction, constituent materials, treatment and other characteristics.<\/p>\n

          Current BIS LIMS testing scopes include checks associated with general requirements and rope construction.<\/p>\n

          Construction and Manufacture<\/h3>\n

          The construction of the rope must correspond to the applicable rope type.<\/p>\n

          This includes the arrangement and construction of the strands and yarns used to manufacture the rope.<\/p>\n

          Lay or Pitch<\/h3>\n

          The applicable pitch or length of lay<\/strong> is an identified requirement.<\/p>\n

          BIS LIMS currently lists pitch or length-of-lay testing for IS 5175:2022.<\/p>\n

          Linear Density<\/h3>\n

          Linear density is an important physical characteristic specified under the standard.<\/p>\n

          The BIS LIMS scope identifies linear-density testing under the relevant tables of IS 5175:2022.<\/p>\n

          Minimum Breaking Strength<\/h3>\n

          The standard specifies minimum breaking strength<\/strong> requirements for the applicable rope type, material and reference number.<\/p>\n

          This is one of the key performance characteristics evaluated during testing.<\/p>\n

          Marking and Labelling<\/h3>\n

          The standard contains marking and labelling requirements, and current BIS laboratory scopes identify applicable marking and labelling checks.<\/p>\n

          Important BIS Tests for Polypropylene Fibre Ropes<\/h2>\n

          Testing is an essential part of BIS certification.<\/p>\n

          Depending on the product configuration and applicable scope, testing may include:<\/p>\n

            \n
          • Material identification<\/li>\n
          • General requirements<\/li>\n
          • Construction and structure<\/li>\n
          • Rope type<\/li>\n
          • Pitch or length of lay<\/li>\n
          • Diameter\/reference number<\/li>\n
          • Linear density<\/li>\n
          • Minimum breaking force<\/li>\n
          • Workmanship<\/li>\n
          • Treatment<\/li>\n
          • Marking and labelling<\/li>\n
          • Packaging and delivery-length requirements<\/li>\n<\/ul>\n

            Current BIS LIMS records show these types of testing parameters for IS 5175:2022.<\/p>\n

            Diameter and Reference Number<\/h2>\n

            The BIS Product Manual identifies reference number<\/strong> as an important part of the certification scope, with the reference number corresponding approximately to rope diameter.<\/p>\n

            The manufacturer therefore needs to identify the reference numbers of the ropes intended to be covered by the BIS licence.<\/p>\n

            Linear Density Testing<\/h2>\n

            Linear density is tested according to the applicable requirements of IS 5175:2022.<\/p>\n

            Current BIS LIMS listings include linear-density testing for the relevant tables covering polypropylene rope types.<\/p>\n

            The result must meet the applicable nominal value and tolerance requirements for the selected rope construction and reference number.<\/p>\n

            Minimum Breaking Force Testing<\/h2>\n

            Minimum breaking force is one of the most important performance parameters for fibre ropes.<\/p>\n

            The test establishes whether the rope can meet the minimum breaking-force requirement corresponding to its applicable type, material and reference number.<\/p>\n

            Current BIS LIMS listings specifically identify Minimum Breaking Force<\/strong> testing under Clause 6 and the relevant tables of IS 5175:2022.<\/p>\n

            UV Treatment and Stabilization<\/h2>\n

            Polypropylene ropes may require suitable treatment or stabilization for their intended service conditions.<\/p>\n

            The BIS laboratory scope identifies testing\/checks associated with UV inhibitor\/stabilizer identification<\/strong> as part of the applicable general requirements in some laboratory testing packages.<\/p>\n

            Manufacturers should ensure that the material formulation and treatment used in production are consistent with the requirements applicable to their certified product.<\/p>\n

            BIS Testing Charges for IS 5175:2022<\/h2>\n

            Testing charges are not one fixed amount for every manufacturer.<\/p>\n

            They depend on:<\/p>\n

              \n
            • Laboratory<\/li>\n
            • Rope type<\/li>\n
            • Material category<\/li>\n
            • Reference number<\/li>\n
            • Testing scope<\/li>\n
            • Applicable parameters<\/li>\n
            • Number of varieties being evaluated<\/li>\n<\/ul>\n

              Current BIS LIMS listings show different testing packages. For example, one current listing shows \u20b99,600 excluding taxes<\/strong> for an indicated testing scope, while another laboratory lists \u20b97,250 excluding taxes<\/strong> and other current laboratory entries show different amounts.<\/p>\n

              Another current BIS laboratory scope lists a testing package of approximately \u20b914,900 excluding taxes<\/strong> for IS 5175:2022.<\/p>\n

              Therefore, manufacturers should obtain the applicable laboratory quotation after finalizing the proposed BIS product scope.<\/p>\n

              BIS Product Sampling and Grouping<\/h2>\n

              The grouping and sampling strategy is particularly important for polypropylene ropes because the standard covers multiple materials, constructions, reference numbers and termination configurations.<\/p>\n

              The BIS Product Manual specifies scope parameters including:<\/p>\n
