Aperçu de conformité

Cet aperçu n’est actuellement disponible qu’en anglais.

Champ d’application

This standard applies to fire-resistant glass used in building construction, specifically covering laminated fire-resistant glass (FFB) and monolithic fire-resistant glass (DFB) manufactured via a tempering process. It is applicable to architectural safety glazing materials but excludes automotive or other specialized industrial glass not intended for building applications. Manufacturers producing safety glass for building doors, windows, and partitions must comply with this standard.

Exigences techniques

The standard categorizes fire-resistant glass into Class A (insulated type) and Class C (integrity-only type) based on their fire performance. Class A must meet both fire integrity and thermal insulation requirements, while Class C only requires fire integrity. The standard defines five fire resistance limit grades ranging from 0.50h to 3.00h. It specifies strict dimensional and thickness tolerances for both laminated and monolithic glass. Appearance quality requirements dictate acceptable limits for bubbles, impurities, scratches, and edge damages. Products must not exhibit cracks or degumming. Additionally, the standard outlines parameters for visible light transmittance, bow curvature, and specific durability requirements for laminated glass, including heat resistance, cold resistance, and UV radiation resistance. Monolithic glass must meet specific fragment status and impact resistance criteria to ensure safety upon breakage.

Méthodes d’essai

Testing procedures include fire resistance tests conducted according to GB/T 12513-2006 using actual maximum dimensions. Impact resistance and fragment status tests follow methodologies outlined in GB 15763.2-2005. Environmental durability tests evaluate heat resistance (using a constant temperature oven), cold resistance (using a low-temperature chamber), and UV radiation resistance (following GB/T 5137.3-2002). Manufacturers must also conduct routine tests for dimensions, appearance, and curvature during factory exit inspections.

Questions fréquentes

What products are regulated under GB 15763.1-2009?

This standard regulates fire-resistant glass used in buildings, specifically covering laminated fire-resistant glass (FFB) and monolithic fire-resistant glass (DFB). It applies to products manufactured for architectural safety glazing.

Are there any major updates from the previous version of GB 15763.1?

The 2009 version added definitions for fire resistance limits, removed the previous Category B fire-resistant glass, added scratch defect requirements for laminated glass appearance, and redefined the fire resistance limit grades into five tiers ranging from 0.50h to 3.00h.

How does GB 15763.1-2009 differ from international fire glass standards?

The standard references international principles similar to BS EN 357:2004 and BS 6262-3:2005. However, it establishes specific Chinese compliance categories (Class A and Class C) and mandates distinct marking formats and testing protocols tailored to the domestic market. Manufacturers must adhere strictly to GB parameters rather than assuming direct ISO equivalence.
