StonePly - The Facts

Why we say failure is not an option

Summary of StonePly Testing By Independent Laboratories

Introduction

StonePly is committed to producing the finest quality. As the World leader in natural stone / honeycomb composite panells, StonePly observes rigorous quality control procedures and testing. Owners and specifiers receive the peace of mind that comes from knowing StonePly has been subjected to testing well beyond the code minimum. Testing is performed at both independent national laboratories and universities as well as StonePly's own research and manufacturing facilities.

General Testing - Summary

Test	Method	Result
Tensile Bond	Marble faced StonePly tested per ASTM D297 standard test for flatwise tensile strength of sandwich constructions after 130 heat and cool cycles	272psi (39,168 psf) stone splitting indicating adhesive bond strength greater than the stone strength for marble 333psi (47,952psf) for granite
Positive and Negative Wind loads	ASTM E330	Tested to pressures in excess of 180 psf. (245 mph wind) No delamination or disengagement. ASCE 7-98 results vary based on height, location, etc.
Salt Spray Resistance	ASTM B117	300 hours. No deleterious effects.
Freeze/Thaw	ASTM C67	Passed. 100 cycles. No checking, delaminating, cracking or splitting.
Water Resistance	ASTM D2247	Passed. No deleterious effects after 120-day exposure.
Mildew/Fungus Resistance	ASTM D3273	Passes. Tested with both granite and marble.
Water Penetration	ASTM E331	Passed. No water penetration to the innermost plane of the wall.
Large Missile Impact Test	ASTM 1996-05B Specifications for Performance of Exterior Windows, Curtain Walls, Doors and Impact Protective Systems Impacted by Windborne Debris in Hurricanes	Passed. A weighted 2x4 was fired at the StonePly panel at 50 fps. There was no penetration
Accelerated Weathering	ASTM G53	2000 hours. No deterioration.
Air and Water Infiltration	ASTM E 283-7	Passed
Absorption – Freeze/Thaw	Panels soaked in water @ 20 °C for 4 days, then placed at –10 °C for 2 hours and +20 °C for 2 hours.	100 cycles. No delamination or failure.
Uniform Static Deflection	ASTM E 330-02 Standard Test Method for Structural Performance of Exterior Windows, Doors, Skylights and Curtain Walls by Uniform Static Air Pressure Difference.	After three years of exposure to two different climates, three panels were tested under uniform static air pressure at 70 psf (approx. 165mph wind) and 105 psf to test structural performance. No attachment or panel failure.
Static Pressure	ASTM E 330-00 Standard Test Method for Structural Performance of Exterior Windows, Doors, Skylights and Curtain Walls by Uniform Static Air Pressure Difference.	Static Pressure tests were performed to determine if it met the performance requirements for a category 5 hurricane force winds. The panel was tested at 160 psf. All the panels tested met or exceeded requirements.
Cyclic Pressure Loading	ASTM E 1886-05 Standard Test Method for Performance of Exterior Windows, Curtain Walls, Doors, and Impact Protective Systems Impacted by Missile(s) and Exposed to Cyclic Pressure Differentials	To test repeated positive and negative loads, over 4,500 positive and negative pressure cycles were applied at ±70 psf. (70psf is = 165mph winds) (psf to mph conversion factors vary based on height, location, etc.)
Flexural Strength	Modified ASTM C880 Standard method for determining flexural strength of dimension stone	Average wet specimen tested 2,379psi
Freeze Thaw	Modified ASTM C666 "Standard test method for resistance of concrete to rapid freeze thaw"	Average flexural strength 1996psi after 100 freeze thaw cycles
Hard Body Impact	From the "Code of practice for design of non-loading bearing external vertical enclosures to buildings". The test methods in BS 8200: 1985 measure the resistance of the specimen test wall to soft and hard body impact. Test is conducted on front face and side face of panel.	No damage: Passed Tested to 10 Nm
Modulus of Rupture	Modified ASTM C99	Average wet specimen tested 3,073psi
Bond Strength	Modified ASTM C482 "Standard test for bond strength"	333psi or 47,952psf
Linear Thermal Expansion	ISO 10545-8 tested from room temperature to 100°C	12.53 X 10-6 per °C
Accelerated Weathering in Acid Bath	100 cycles of freeze + heat. -10 to 170 degrees F while partially submerged in a 4ph sulpherous acid solution.	Less than 11% reduction in flexural strength. No significant difference in load deflection of exposed vs. not exposed specimens.
Temperature Cycling	Panel 42" by 58" exposed to 130 cycles rapid heating and cooling from 140 to 65 degrees F	No damage or bowing recorded 272psi tensile bond strength
Fastener Pull Out Strength	Self-tapping #8 screws by 3/4" long	399lbs. average per screw
Deflection	24" X 34" Panel center loaded with 1,600lbs. Supports placed at 34"	Deflection was less than .032"

Fire Testing - Summary

Test	Method	Result
"Tunnel Test"	ASTM E84	Flame spread 0 Smoke developed 0
Fire Endurance Test	Modified ASTM E 119	System remained in place during a 30-minute fire exposure test. Conducted per modified ASTM E119 "Standard Methods of Fire Endurance Tests of Building Construction and Materials."
Diversified Fire Test	Modified ASTM E108	Fire hazard = 0
Standard Fire Exposure Test	ASTM E119	Fire resistance rating of one-hour and two-hour wall assemblies was not reduced by the addition of the StonePly.
Radiant Heat Exposure Test	NFPA 268 Standard Test Method for Determining Ignitibility of Exterior Wall Assemblies Using a Radiant Heat Energy Source	Meets requirement for unrestricted fire separation distance. No flaming at 12.5 KW/m2 heat flux exposure. This test is designed to simulate a thermal radiation exposure to an exterior wall from a radiant panel heated to 1600 °F
