Fire Rating Classifications per International Standards & Tests
(class A1 is the highest rating for building materials)

European Standards UNI EN ISO 1182 (non-combustible) - Euroclass A1
European Standards UNI EN ISO 1716 (heat resistance) - Euroclass A1
European Standards UNI EN ISO 13501-1 (smoke and flame) - Euroclass A1
European Standards UNI EN ISO (flooring material) - Euroclass A1FL

United States & Canada US ASTM E136 - non-combustible
British Standard 476: Part 4 : 1970 - non-combustible

United States and Canada Surface Burning Characteristics
CAN/ULC-S102 and US ASTM E 84
(Flame Spread Classification "FSC" = 0 / Smoke Developed "SD" = 0)
Flame Spread and Smoke Development Rating is Class 1 or Class A

British Standard 476: Part 7 : 1997, Class 1 for Surface Spread of Flame

ACOUSTICAL ASSEMBLY TEST RESULTS: ASTM E90
9mm (~3/8") Magnesiacore vs ~15mm (5/8") gypsum board
[~15mm gypsum] + [metal stud & batts] + [~15mm gypsum] = STC 43
magnesiacore only wall [9mm] + [metal stud & batts] + [9mm] = STC 48
[9mm / goo / 9mm] + [wood stud & batts] + [~15mm gypsum] = STC 50
[9mm / goo / 9mm] + [wood stud & batts] + [9mm / goo / 9mm] = STC 55
[9mm / goo / 9mm] + [metal stud & batts] + [9mm] = STC 55
[9mm / goo / 9mm] + [metal stud & batts] + [9mm / goo / 9mm] = STC 60

Note * STC 50 is typical code requirement for hotels, motels, apartments,
condominiums, monasteries and convents blocking approx 50 dB (loud speech
cannot be understood). STC 60 is typically specified for highly sensitive areas
blocking around 60 dB off sound volumes (loud speech cannot be heard).

ONE HOUR FIRE RATED ASSEMBLY TEST:
Passed tests for one hour fire rated wall assembly
using 12mm (1/2") Magnesiacore thickness
(After one hour only the joint compound is breaking down)


0-min	55-min	70-min	80-min	95-min

NOTE: Separate certification of each fire rated assembly is required in most jurisdictions to comply with local building codes. Fire Rated certification is not currently available for most assemblies and countries. Based on past tests conducted fire rated certification is achievable to higher levels than common fire code / rated materials. Please contact us for more information.

ADHESION TESTS:
