HaanGlas VIG Passed ANSI Z97.1 impact test
HaanGlas tempered vacuum insulating glass,passed ANSI Z97.1 test in Intertek,show end users the safety performance and unlimited application in windows,doors and glass facades.
ANSI Z97.1 is the American National Standard for Safety Glazing Materials for Buildings. It specifies safety performance specifications and test methods for safety glazing materials for all building and construction purposes.
ANSI Z97.1 sets minimum safety performance characteristics for safety glazing materials and provides the basis for regulatory adoption by federal, state, and local regulatory agencies and safety standards for use by building code officials, architects, and designers.
End users will be able to see if their safety glass material is compliant with the ANSI Z97.1 mark, which can be found on everything from bathroom doors to glass on escalators.
The glass that pass ANSI Z97.1 means that glass will not break,or even if glass is broken,glass will break into many small fragments and won;t cause serious injury to people under certain impact.The impact can be human body impact,or other heavy materials impact on glass surface.
For many years, vacuum insulating glass cannot pass ANSI Z97.1 because earlier vacuum glass were always annealed VIG,this kind of VIG can only be used in low rise buildings with 1-3 stories ,which limit the large scale application of vacuum glazing.
Then tempered vacuum glazing was invented to have higher strength and has better safety performance.Even though the pillars inside VIG may decrease VIG overall strength,but tempered vacuum glass can still break into small particles and won’t hurt people.
HaanGlas tested 4mm,5mm, 8.3mm VIG and 10.3mm VIG in the test and test results shows VIG and the VIG monolithic lite is safety enough when been installed in high rise buildings,below is the result:
HaanGlas will keep conducting more tests and prove VIG excellent performance and long lifetime.
