Heat Soak Testing Furnace Independently Calibrated at a UK Customer Factory

We are pleased to share a recent project update from a customer factory in the United Kingdom, where our heat soak testing furnace was inspected, calibrated and verified by an independent third-party calibration engineer.

The calibration was carried out to support the customer's production of heat soaked thermally toughened safety glass in line with EN 14179-1 / BS EN 14179-1 requirements.

Unlike a simple internal equipment check, this on-site verification was performed by a professional third-party calibration specialist. This gives the customer greater confidence in the furnace’s temperature control, process stability and suitability for heat soak testing in a real production environment.

Full-Load and 10% Load Testing for Real Production Conditions

During the calibration process, the heat soak testing furnace was tested under two important loading conditions:

100% full-load testing was carried out to verify the furnace performance under maximum production capacity. This is important for glass processors who need stable temperature control, reliable air circulation and consistent heat distribution when the furnace is fully loaded with toughened glass.

10% load testing was also carried out to evaluate the furnace under low-load production conditions. This is valuable for customers who process smaller batches, special glass sizes, urgent orders or project-based production runs.

The successful completion of both tests demonstrated that the glass heat soak oven can maintain stable performance across different loading conditions, from small-batch operation to full-capacity production.

Why These Tests Matter for Glass Processors

For architectural glass manufacturers, production conditions are not always the same. Some projects require large quantities of façade glass, while others involve small batches of special glass panels, replacement glass or customized sizes.

A reliable HST furnace should therefore perform well not only when fully loaded, but also when operating with a lower load. By testing the furnace under both full-load and 10% load conditions, the customer gained a clearer understanding of the furnace’s operating stability in practical production scenarios.

This helps support:

• More consistent heat soak testing performance
• Better confidence in different production loads
• Improved process traceability
• Stable temperature control for full-capacity production
• Flexible operation for small-batch glass processing
• Quality control for architectural toughened safety glass

Supporting EN 14179-1 Heat Soaked Toughened Glass Production

EN 14179-1 is widely referenced in the glass industry for heat soaked thermally toughened soda lime silicate safety glass used in buildings. In the UK market, it is commonly referred to as BS EN 14179-1

For glass processors, a properly calibrated heat soak furnace is an important part of the heat soak process system. It supports controlled heating, stable holding conditions, accurate temperature monitoring and production documentation.

Our furnace is designed to help customers carry out professional heat soak testing for toughened glass, supporting production quality for building glass, façade glass, curtain wall glass, balustrade glass and other architectural safety glass applications.

Independent Third-Party Calibration Adds Customer Confidence

One of the key highlights of this UK project was the involvement of an independent third-party calibration engineer.

Third-party calibration provides additional credibility because the furnace performance is checked by an external professional rather than only by the equipment manufacturer or the customer’s internal team.

For customers, consultants and project stakeholders, this independent verification helps demonstrate that the heat soak testing furnace has been checked under controlled and documented conditions.

It is especially valuable for glass processors working on demanding architectural projects where process control, documentation and compliance support are essential.

Reliable Heat Soak Furnace Technology for Architectural Glass

Our heat soak testing furnaces are engineered for glass processors that require reliable operation, accurate temperature control and stable performance in daily production.

The equipment is suitable for a wide range of applications, including:

• Heat soaked toughened glass
• Tempered safety glass
• Façade glass
• Curtain wall glass
• Balustrade glass
• Commercial building glass
• Structural glazing projects
• Architectural safety glass production

With robust furnace construction, controlled air circulation, precise temperature monitoring and user-friendly operation, our heat soak furnace helps customers improve production quality and process reliability.

A Successful UK Project

The successful calibration at the UK customer factory confirms the performance of our heat soak testing furnace under real production conditions.

Verified by an independent third-party calibration engineer and tested under both full-load and 10% load conditions, the furnace demonstrated the stability and reliability required by professional glass processors.

This project reflects our commitment to providing dependable heat soak testing solutions for customers in the UK, Europe and global architectural glass markets.

Conclusion

This UK project is an excellent example of how a high-quality heat soak testing furnace can support modern glass production.

Through independent third-party calibration, 100% full-load testing and 10% load testing, the furnace demonstrated stable operation, reliable temperature control and strong suitability for heat soak testing of toughened safety glass.

For glass processors looking for an EN 14179-1 heat soak furnace, BS EN 14179-1 glass heat soak oven, or HST furnace for tempered glass, our company provides reliable equipment and technical support for professional architectural glass production.
