"Strong glass builds strong trust. At Presto Laboratories, we test automotive, construction, and appliance glass for strength, safety, and compliance — To protects, to perform, and to last."
Glass is not merely a material; it is a safety barrier, design feature, and performance enhancer. Be it an automobile window, exterior, solar panel shield, or sheet voltage inside an appliance, it should not give way to impact, pressure, or even a weather extremity.
At Presto Laboratories, we provide comprehensive glass testing services that validate safety, durability, and global compliance. Our QAI -accredited lab ensures your glass products meet QAI, ISO, IEC, ASTM, and international standards, giving you the confidence to deliver products that protect and perform.
What We Test
- Automotive Glass – windshields, windows, and mirrors
- Construction Glass – tempered, laminated, and toughened
- Appliance Glass – oven doors, refrigerator shelves, and microwave panels
- Solar Glass – protective covers for PV modules Safety & Architectural Glass – bullet-resistant, fire-rated, decorative

Standards We Help You Meet
Stay ahead of compliance with our expertise in:- (IS 2553, IS 14900, etc.)
- ECE R43 (Automotive Glass Standard)
- ASTM Standards (D1044, E2353, etc.)
- ISO Standards (ISO 718, ISO 614, etc.)
- ANSI Z97.1 (Safety Glazing Materials)
The testing of glass at Presto Laboratories is guided by a systematic scheme of both Indian and international guidelines. These standards help in the determination of the testing of glass about its strength, safety, and long-term performance. They also assist manufacturers in complying with local and international markets.
- IS 2553 is widely used for testing safety glass in India. It includes crucial tests like impact resistance, fragmentation, thermal shock, and optical quality. This standard is significant to auto and construction glass that needs safety.
- IS 14900 focuses on toughened safety glass used in buildings. It checks mechanical strength and resistance to sudden stress conditions. This helps confirm that glass can handle real use conditions without failure.
- ECE R43 is a global standard for automotive glass. It sets a tight standard of optical clarity, transference, and fragmentation. Exportation of automotive glass to the foreign market needs adherence to this standard.
- ASTM standards like ASTM D1044 and ASTM E2353 are concerned with abrasion resistance and impact tests. These tests can be used to measure the durability of surfaces and the ability to withstand mechanical damages in the long term.
- The ISO standards such as the ISO 718 and the ISO 614 concentrate on thermal resistance and performance with changes in temperature. These standards are used to evaluate the relevance of the glass towards unexpected heating and cooling.
- ANSI Z97.1 is a standard that applies to architectural glass as a safety glazing. It evaluates impact resistance and breakage pattern to reduce injury risk.
These standards together make an entire testing framework. They assist manufacturers in testing the product's strength, safety, and compliance before using them in the market.
