EN 356
Quality: BEST
The most robust classification, including multiple ratings from “impact resistant” to fully “burglar resistant.” By far the most accurate, repeatable, and wide-ranging test available.
ISO 16936
Quality: BEST
In the case of security glazing the ISO standard defaults (is the same) as the EN 356 standard, in testing methodology, outputs, and the naming convention (mostly). Helpful if you need to specify the use of a robust, internationally recognized standard instead of a European standard.
UL 972
Quality: BETTER
Precise and repeatable, though only one rating. Based on a standard size ball dropped multiple times from a known height.
ASTM F1233
Quality: GOOD
Very broad and not repeatable. Based on human interactions with the glass. For example, two attackers with a 12 lbs sledge hit the window 25 times. How tall are the attackers? Are they getting tired as the test progresses? Are they strong or weak individuals? These results are HIGHLY subjective, and the output can only be based on assumption.
SecureGlaze™ is AGNORA's answer to security specific glazing for high-end retail, commercial, institutional, and residential applications. Third-party certification for European P6B and P8B designations allows AGNORA to fulfil stringent anti-theft and burglary requirements by providing an extremely high level of resistance to forced entry by manual attack.
What's the difference between security film and security glazing? Security film and security interlayers are strikingly different, and though they share similar trade names, their ratings and intended use are a different story.
In this article, we "break down" and compare the standards surrounding security glazing and the associations that produce them. We also chart the maximum energy each test can endure and how relevant the test is to your applications.
