Imagine a glass exterior on a commercial building that appears entirely clear from the outside. Hidden behind that clear appearance are several important quality aspects: light transmission, uniform thickness, dimensional accuracy, and the absence of any visible flaws. Should these features fail to comply with the specified requirements, the glass could fail to provide the performance that builders, architects, and buyers expect.
BIS Certification for transparent float glass is important here. In India, transparent float glass is subject to a mandatory quality control system which requires that the relevant products comply with the applicable Indian Standard and display the BIS Standard Mark under the appropriate licence. The order for government-issued Transparent Float Glass (Quality Control) Order, 2021 states IS 14900 as a relevant standard while appointing an authority in the form of the Bureau of Indian Standards (BIS) that would be responsible for certification and compliance of the same.
It is important to note that for a producer looking to enter the market with construction materials, obtaining certification does not mean a simple label; it requires full-scale manufacturing control, laboratory testing, documentation, and following the respective regulations in the sector.
The blog post outlines how BIS ISI Certification in India helps to ensure compliance, what preparations manufacturers have to make, and the way in which UMSPCS can help to simplify the process.
What is Transparent Float Glass and Why Does it Require BIS Certification?
Transparent float glass is made by floating molten glass over a bath of molten metal, generally tin. The result is a glass sheet which is relatively flat, smooth, and uniform and is used in windows, façades, partitions, and as a base material for further glass processing.
The transparent float glass specification sets out several important characteristics as identified by the Bureau of Indian Standards, such as visual light transmission, thickness tolerances, dimensions, optical and visual faults, defects at the cut edge, and the ability to identify the tin side. The specification also includes provisions regarding packaging and marking.
If strict manufacturing controls are not maintained, glass sheets can show scratches, bubbles, dimensional variations, or other defects which affect their usability.
BIS certification offers manufacturers the ability to demonstrate their compliance with the requisite Indian Standard as well as establish a formal check on those products that fall within the ambit of a mandatory Quality Control Order (QCO).
How Does the Certification Help Manufacturers Ensure Compliance with Indian Standards?
The certification connects product quality with company compliance in terms of both regulations and manufacturing standards. Among its practical advantages are:
- Standardised product quality
- Regulatory compliance
- Buyer confidence
- Better quality control
- Improved market access
- Stronger production documentation
The benefits mentioned can be used to aid Indian manufacturers with their domestic production planning, quality assurance, and their dealings with distributors of construction materials and with project buyers.
The process aids foreign manufacturers in becoming familiar with the technical requirements in India before they supply their products there for BIS Certification; it should be noted that the certification does not take the place of separate import, customs, or other relevant legal obligations.
Basic Requirements Before Applying for BIS ISI Certification
It is essential to prepare, since obtaining BIS ISI certification for transparent float glass requires both testing the product and evaluating the manufacturing controls.
Before applying, manufacturers should review the following requirements:
- Manufacturing facility
- Product identification

The product manual from the BIS for IS 14900:2018 includes useful reference material on product grouping, sample size, testing equipment, and the Scheme-I inspection and testing framework, and states that a sample of three pieces, each measuring 1 m × 1 m, should be used in the version in question. It is necessary to verify the current sampling instructions before sending in the samples.
