Technical Requirements Under IS 14900:2018<\/h2>\n<p>The Indian Standard specifies several important characteristics that transparent float glass must satisfy.<\/p>\n<h3>A. Identification of Float Glass Technology<\/h3>\n<p>The standard specifies a UV test to identify the tin side of float glass.<\/p>\n<p>This test helps establish whether the glass has been manufactured using the float glass technology.<\/p>\n<h3>B. Visual Light Transmission<\/h3>\n<p>Visual light transmission is an important quality characteristic of transparent float glass.<\/p>\n<p>The standard specifies minimum visual light transmission values for commonly used thicknesses up to 25 mm.<\/p>\n<p>The purpose is to ensure adequate transparency and clarity.<\/p>\n<h3>C. Dimensions and Tolerances<\/h3>\n<p>The standard specifies requirements relating to:<\/p>\n<ul>\n<li>Nominal thickness<\/li>\n<li>Length<\/li>\n<li>Width<\/li>\n<li>Squareness<\/li>\n<\/ul>\n<p>Thickness tolerances are important because variations can affect the performance and processing of glass.<\/p>\n<h3>D. Optical Faults<\/h3>\n<p>Optical faults can affect the visual appearance and optical quality of glass.<\/p>\n<p>The standard specifies permissible requirements for optical faults, including the evaluation of distortion and related imperfections.<\/p>\n<h3>E. Visual Faults<\/h3>\n<p>The standard specifies requirements for visual imperfections, including:<\/p>\n<ul>\n<li>Bubbles<\/li>\n<li>Scratches<\/li>\n<li>Spot faults<\/li>\n<li>Reams<\/li>\n<li>Strings<\/li>\n<li>Lines<\/li>\n<li>Linear and extended faults<\/li>\n<\/ul>\n<h3>F. Defects on Cut Side<\/h3>\n<p>The cut edges of glass must comply with the applicable requirements specified in the standard.<\/p>\n<h3>G. Bloom \u2013 Optional Requirement<\/h3>\n<p>Bloom is an optional requirement under IS 14900:2018.<\/p>\n<p>If the manufacturer intends to include this optional requirement in the BIS licence scope, the relevant sample must also be tested for bloom.<\/p>\n<p>The exact permissible limits and test conditions must be taken from the applicable edition of IS 14900 and its amendments.<\/p>\n<h2>5.

Common Challenges in BIS Certification for Transparent Float Glass<\/h2>\n<p>Manufacturers may face several challenges during BIS certification.<\/p>\n<h3>1. Thickness Tolerance Failure<\/h3>\n<p>The manufacturer may face difficulty in maintaining uniform thickness within the limits specified by the standard.<\/p>\n<h3>2. Visual Light Transmission Failure<\/h3>\n<p>Inadequate transparency or variations in glass composition may affect visual light transmission results.<\/p>\n<h3>3. Optical Faults<\/h3>\n<p>Optical distortion, reams, strings and lines may lead to non-conformity during testing.<\/p>\n<h3>4. Visual Faults<\/h3>\n<p>Bubbles, scratches and spot faults can affect the acceptability of the glass.<\/p>\n<h3>5. Inadequate Laboratory Infrastructure<\/h3>\n<p>Manufacturers may not have the required UV testing setup, spectrophotometer, optical fault testing arrangements or measuring instruments.<\/p>\n<h3>6. Improper Control Unit Definition<\/h3>\n<p>Failure to establish suitable control units and testing frequencies can affect the implementation of the SIT.<\/p>\n<h3>7. Incorrect Licence Scope<\/h3>\n<p>The manufacturer must ensure that the proposed thickness range and optional bloom requirement are correctly declared.<\/p>\n<h3>8. Transition to IS 14900:2026<\/h3>\n<p>Manufacturers operating under IS 14900:2018 must prepare for the new edition before the scheduled withdrawal date of 28 February 2027.<\/p>\n<p>A proper gap assessment can help manufacturers identify technical and documentation issues before applying for BIS certification.<\/p>\n<h2>15.

Frequently Asked Questions (FAQs)<\/h2>\n<p><strong>Q1. Is BIS certification mandatory for transparent float glass in India?<\/strong><\/p>\n<p>Yes. Transparent float glass covered under the Transparent Float Glass Quality Control Order must comply with the applicable Indian Standard and bear the BIS Standard Mark under a valid licence.<\/p>\n<p><strong>Q2. Which Indian Standard applies to transparent float glass?<\/strong><\/p>\n<p>IS 14900:2018 is the First Revision. BIS established IS 14900:2026 as the Second Revision on 28 August 2026.<\/p>\n<p><strong>Q3. Is IS 14900:2018 still valid?<\/strong><\/p>\n<p>Yes. BIS has notified that IS 14900:2018 will remain in force concurrently with IS 14900:2026 until 28 February 2027, when the 2018 edition is scheduled to be withdrawn.<\/p>\n<p><strong>Q4. What is the sample quantity required for BIS testing under IS 14900:2018?<\/strong><\/p>\n<p>As per PM\/14900\/2, February 2023, the sample quantity is three pieces of glass, each measuring 1 metre \u00d7 1 metre.<\/p>\n<p><strong>Q5. What are the grouping guidelines for transparent float glass?<\/strong><\/p>\n<p>Samples of the highest and lowest thicknesses in the proposed range may be tested. If both pass and the manufacturer has the necessary facilities, the licence may cover the thicknesses within that range.<\/p>\n<p><strong>Q6. What is the optional bloom requirement?<\/strong><\/p>\n<p>Bloom is an optional requirement under IS 14900:2018. If the manufacturer wants to include it in the licence scope, the sample must be tested for bloom.<\/p>\n<p><strong>Q7. What are the major tests required under IS 14900:2018?<\/strong><\/p>\n<p>The major tests include UV identification of the tin side, visual light transmission, thickness, dimensions, squareness, optical faults, visual faults, cut-side defects and optional bloom.<\/p>\n<p><strong>Q8. Is an in-house laboratory required?<\/strong><\/p>\n<p>The product manual requires a suitably equipped and staffed laboratory. It also states that applications from new manufacturing units in India may be processed on a factory-testing basis if the unit has complete in-house testing facilities.<\/p>\n<p><strong>Q9. What is the control unit for transparent float glass?<\/strong><\/p>\n<p>The total quantity produced in one day from the same batch of raw material under similar conditions constitutes one control unit under the February 2023 product manual.<\/p>\n<p><strong>Q10. What information must be marked on each piece of float glass?<\/strong><\/p>\n<p>The product manual specifies the words \u201cFloat Glass\u201d, indication of source of manufacture and thickness. The Standard Mark and CM\/L number must also be marked as required by the licence and product manual.<\/p>\n<p><strong>Q11. Can transparent float glass be manufactured without an ISI Mark?<\/strong><\/p>\n<p>Products covered by the applicable QCO cannot be manufactured, imported, sold or distributed in India without complying with the applicable mandatory certification requirements, subject to the stated exemptions.<\/p>\n<p><strong>Q12. Can foreign manufacturers obtain BIS certification for transparent float glass?<\/strong><\/p>\n<p>Yes. Eligible foreign manufacturers may apply through the BIS Foreign Manufacturers Certification Scheme (FMCS), subject to the applicable requirements, inspection and testing arrangements.<\/p>\n<p><strong>Q13. Who can assist with BIS certification for transparent float glass?<\/strong><\/p>\n<p>Qualitance India can assist manufacturers with product grouping, thickness scope assessment, documentation, laboratory readiness, sample testing coordination, factory inspection preparation and BIS certification support.<\/p>\n<div>\n<hr \/>\n<\/div>\n<h2>Conclusion<\/h2>\n<p>BIS certification for transparent float glass under IS 14900 is an important regulatory requirement for manufacturers supplying covered products in India.<\/p>\n<p>The certification process requires careful attention to thickness tolerances, visual light transmission, optical faults, visual defects, dimensions, squareness, laboratory arrangements and production quality-control systems.<\/p>\n<p>With the introduction of IS 14900:2026, manufacturers currently certified under IS 14900:2018 should also plan for the transition before 28 February 2027.<\/p>\n<p>For professional assistance with <strong>BIS Certification for Transparent Float Glass<\/strong>, contact Qualitance India.<\/p>\n<p><strong>Qualitance India \u2013 Improving Quality &amp; Competence<\/strong><\/p>\n<p>Website: <a href=\"https:\/\/qualitanceindia.com\/\">https:\/\/qualitanceindia.com<\/a><br \/>\nEmail: <a href=\"mailto:info@qualitanceindia.com\">info@qualitanceindia.com<\/a><br \/>\nPhone: +91 93106 15170<\/p>\n<div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>BIS Certification for Transparent Float Glass \u2013 IS 14900:2018 Transparent float glass is widely used in the construction, architectural, automotive and glass-processing industries.
