Obtain a current, itemised quotation for the intended product scope and confirm the applicable BIS fee schedule.<\/p>\n<h2>13. How Long Does BIS Certification Take?<\/h2>\n<p>The completion time depends on the applicant&#8217;s readiness, laboratory availability and the applicable certification procedure.<\/p>\n<p>Key factors include:<\/p>\n<ul>\n<li>Completeness of application documents<\/li>\n<li>Manufacturing and laboratory readiness<\/li>\n<li>Availability of the required testing facilities<\/li>\n<li>Sample preparation and dispatch<\/li>\n<li>Completion of tensile and other routine tests<\/li>\n<li>UV-resistance testing after 500 hours of exposure<\/li>\n<li>Chemical-resistance testing after 72 hours of immersion<\/li>\n<li>Factory assessment and closure of observations<\/li>\n<li>BIS review and any further technical queries<\/li>\n<\/ul>\n<p>The BIS product manual identifies dimensional stability, ultimate tensile strength, tensile strength at 2% and 5% strain, junction strength, width and roll length as tests that may potentially be completed in one day. This is not a guarantee of the overall certification timeline, especially when longer exposure or immersion tests are required. &lt;Cite refs={[&#8220;turn487430view0&#8221;]}\/&gt;<\/p>\n<p>Manufacturers should obtain a realistic timeline after the product scope, sample availability and laboratory route have been confirmed.<\/p>\n<h2>14. BIS Certification for Foreign Manufacturers<\/h2>\n<p>Foreign manufacturers planning to supply geogrids for flexible pavements to India should verify the applicable BIS certification route before exporting covered products.<\/p>\n<p>The Geo Textiles Quality Control Order excludes goods meant for export, but this should not be interpreted as a general exemption for imported products sold in India. Covered products supplied to the Indian market must comply with applicable requirements, subject to the Order&#8217;s provisions and exemptions. &lt;Cite refs={[&#8220;turn668404search3&#8221;]}\/&gt;<\/p>\n<p>Foreign manufacturers should confirm the applicable requirements for overseas factory assessment, application arrangements, authorised representation and licence scope with BIS.<\/p>\n<p>An overseas laboratory report or an existing quality-management certification does not automatically replace the required BIS product licence.<\/p>\n<h2>15. Common Mistakes to Avoid<\/h2>\n<p>Manufacturers should avoid these common mistakes during BIS certification:<\/p>\n<ol start=\"1\">\n<li><strong>Selecting the wrong polymer scope:<\/strong> PET and PP geogrids require separate samples for testing.<\/li>\n<li><strong>Defining style numbers incorrectly:<\/strong> The style number must reflect the designed ultimate tensile strength in MD and CMD.<\/li>\n<li><strong>Assuming every construction type is covered:<\/strong> The declared scope must be supported by applicable grouping guidelines and testing.<\/li>\n<li><strong>Sending an insufficient sample:<\/strong> The product manual requires at least 4 m\u00b2 of full-width sample material and a fibre or yarn bobbin of at least 1 kg.<\/li>\n<li><strong>Ignoring PET-specific requirements:<\/strong> PET geogrids must meet the additional requirements under Clause 4.4.<\/li>\n<li><strong>Overlooking junction strength:<\/strong> This test is applicable to PP geogrids.<\/li>\n<li><strong>Not maintaining a Quality Assurance Plan:<\/strong> Control units, test frequencies and sample numbers must be documented.<\/li>\n<li><strong>Ignoring UV and chemical-resistance testing:<\/strong> These tests require longer exposure or immersion periods.<\/li>\n<li><strong>Failing to maintain calibration and test records:<\/strong> The applicable laboratory and recordkeeping requirements must be met.<\/li>\n<li><strong>Budgeting from a partial testing quotation:<\/strong> Laboratory charges vary and are separate from other certification costs.<\/li>\n<li><strong>Using the Standard Mark before approval:<\/strong> The mark may only be used in accordance with the granted BIS licence.<\/li>\n<\/ol>\n<h2>16. Frequently Asked Questions (FAQs)<\/h2>\n<h3>Q1. Is BIS certification mandatory for geogrids for flexible pavements?<\/h3>\n<p>Yes. IS 17371:2020 is listed under the BIS Scheme-I compulsory-certification framework associated with the Geo Textiles Quality Control Order. Covered products must conform to the applicable standard and bear the Standard Mark under a licence, subject to the Order&#8217;s provisions and exemptions. &lt;Cite refs={[&#8220;turn668404search0&#8243;,&#8221;turn668404search3&#8221;]}\/&gt;<\/p>\n<h3>Q2. What is the applicable Indian Standard?<\/h3>\n<p>The applicable standard is IS 17371:2020, <em>Geosynthetics \u2014 Geogrids for Flexible Pavements \u2014 Specification<\/em>. &lt;Cite refs={[&#8220;turn487430view0&#8221;]}\/&gt;<\/p>\n<h3>Q3. Which polymer materials are covered?<\/h3>\n<p>The product manual identifies PET and PP as the polymer materials for the licence scope. Separate samples of each polymer type must be tested. &lt;Cite refs={[&#8220;turn205259view0&#8221;]}\/&gt;<\/p>\n<h3>Q4. What is the sample quantity for testing?<\/h3>\n<p>The product manual requires a full-width sample sufficient to provide at least 4 m\u00b2 and one bobbin of fibre or yarn weighing at least 1 kg. &lt;Cite refs={[&#8220;turn487430view0&#8221;]}\/&gt;<\/p>\n<h3>Q5. What is a geogrid style number?<\/h3>\n<p>A style number identifies a geogrid designed for a specific ultimate tensile strength in the machine and cross-machine directions. For example, 30\/40 indicates 30 kN\/m in MD and 40 kN\/m in CMD. &lt;Cite refs={[&#8220;turn487430view1&#8221;]}\/&gt;<\/p>\n<h3>Q6. What are the major tests under IS 17371:2020?<\/h3>\n<p>The product manual identifies dimensional stability, ultimate tensile strength, tensile strength at 2% and 5% strain, UV resistance after 500 hours, chemical resistance after 72 hours, junction strength for PP geogrids, width and roll length. &lt;Cite refs={[&#8220;turn588178view0&#8221;]}\/&gt;<\/p>\n<h3>Q7. Is an in-house laboratory mandatory for every manufacturer?<\/h3>\n<p>The product manual allows MSME manufacturers to use common cluster-based facilities, shared testing facilities or eligible external laboratories instead of maintaining their own routine testing laboratory, subject to the stated provisions. Large-scale manufacturers must maintain the required routine test facilities or use permitted shared testing arrangements. &lt;Cite refs={[&#8220;turn205259view1&#8221;]}\/&gt;<\/p>\n<h3>Q8. What are the testing charges for IS 17371:2020?<\/h3>\n<p>BIS LIMS displays laboratory-specific testing charges of \u20b91,88,350, \u20b92,20,900 and \u20b92,36,000 for different listings. The applicable cost depends on the laboratory and scope; these figures are not universal quotations or the complete cost of BIS certification. &lt;Cite refs={[&#8220;turn852124search0&#8243;,&#8221;turn852124search1&#8243;,&#8221;turn852124search2&#8221;]}\/&gt;<\/p>\n<h3>Q9. When must UV-resistance testing be conducted?<\/h3>\n<p>The product manual specifies UV resistance after 500 hours of exposure, with testing once in three years or whenever the material or process changes. Different geogrid varieties are to be tested in rotation so each variety covered by the licence is tested at least once in three years. &lt;Cite refs={[&#8220;turn588178view0&#8221;]}\/&gt;<\/p>\n<h3>Q10. Can one licence cover multiple geogrid style numbers?<\/h3>\n<p>The grouping guidelines permit consideration of style numbers within a range supported by samples representing minimum and maximum ultimate tensile strength in MD and CMD. Final coverage depends on the applicable grouping rules, testing results, declared scope and manufacturing capability. &lt;Cite refs={[&#8220;turn205259view0&#8221;]}\/&gt;<\/p>\n<h3>Q11. Can a consultant assist with BIS certification?<\/h3>\n<p>Yes. A consultant can assist with product-scope review, documentation, laboratory coordination, factory-readiness checks and application follow-up. The grant of the licence remains a decision of BIS.<\/p>\n<h2>17.
