BIS CERTIFICATION FOR TRANSPARENT FLOAT GLASS IS 14900:2018
Transparent float glass is a type of glass that is known for its smooth, flat surface and exceptional optical clarity. It is made by pouring molten glass over a bed of molten tin, letting it spread as it cools and solidifies, and then leveling it off. With this method, a glass sheet with less deformation is produced.
It offers natural light and clear vistas and is frequently used for windows, doors, mirrors in cars, glass furniture, and building facades.
To ensure the product quality of transparent float glass, the Bureau of Indian Standards (BIS) has made it mandatory for manufacturers to undergo BIS registration and obtain the BIS ISI mark before selling it in the market. Manufacturers can use the ISI Mark on their products only after obtaining a license from BIS that is granted after BIS registration. The presence of the ISI mark on a product indicates that it complies with BIS's stringent quality standards.
Transparent float glasses are covered under IS 14900:2018.
The Bureau of Indian Standards adopted this Indian Standard after the Glassware Sectional Committee's final draught was approved by the Chemical Division Council. This standard specifies the specifications and the sample and testing methods for flat, transparent, clear float glass with glossy, plain, and smooth surfaces. This standard covers cut sizes or stock sheets that are square, rectangular, or other shapes. This standard does not apply to tinted, coated, frosted, heat-absorbing, or low-light-reducing glasses.
