Acid Etch Testing
Derived from ASTM D1308
This test is intended to determine the effect of common acidic graffiti etch agents, on clear and pigmented protective anti-graffiti films resulting in any objectionable alteration of the surface such as discoloration, change in gloss, blistering swelling, or loss of adhesion. The test specimens are exposed to 1.0 mL of acidic etch agent (ammonia/sodium bifluoride, and hydroflouric acid), and effects are recorded for durations of 5 min, 24,48, and 72 hours. The tests can be carried out uncovered and covered. Click on the link to view our testing and test results.

ANSI Z26.1 Test #1 - Light Stability (100 hrs. UV)
The purpose of this test is to determine the regular (parallel) luminous transmittance of the safety glazing material or multiple glazed units before and after irradiation. This is to determine whether or not it is adversely affected by exposure to simulated sunlight over an extended period of time. For this test, panels are measured for light transmittance before and after UV radiation for 100 hours.
Upon conclusion, the regular (parallel) luminous transmittance of the irradiated specimens shall not be reduced by more than 5% from its original value. A slight discoloration, noticeable only when specimens are placed on a white background, is permissible.
ANSI Z26.1 Test #2 - Luminous Transmittance
The purpose of this test is to determine the regular (parallel) luminous transmittance of safety glazing materials intended for use in motor vehicles at levels required for driving visibility. Panels are irradiated similar to test Z26.1 Test #1
Interpretation of Results. Safety glazing materials or multiple glazed units intended for use at levels requisite for driving visibility in the motor vehicle shall show regular (parallel) luminous transmittance of not less than 70% of the light, at normal incidence, both before and after irradiation (Test 1).
ANSI Z26.1 Test #15 - Optical Deviation and Visibility Distortion
The purpose of this test is to measure the optical deviation and visibility distortion effects of flat or curved safety glazing materials or both. The equipment for this test consists of an illuminated box as specified in the standard. The specimen is visually observed by an examiner and compared to definitions of images also spelled out in the standard.
ANSI Z26.1 Test #16 - Weathering (2680 hrs. Xenon Arc)
The purpose of this test is to determine whether safety glazing materials, of which at least one surface is plastic, will withstand exposure to simulated weathering conditions over an extended period of time. The exposure apparatus uses a long arc xenon lamp as the source of the radiation, and exposes the panel to the radiation for a specified number of hours.
The regular (parallel) luminous transmittance of the exposed specimens shall be reduced no more than 5% from its original value. While some discoloration is permissible, no bubbles or other visible decomposition shall develop in the irradiated specimens.
ANSI Z26.1 Test #17 - Abrasion Resistance (Plastics)
The purpose of this test is to determine whether the interior surface of the safety glazing material, as mounted in the vehicle, has a certain minimum resistance to abrasion. The apparatus for the abrasion shall be the Taber Abraser or its equivalent. This test apparatus rotates a specimen under a specific pair of abrasive wheels with a specified fixed weight providing downward force. The samples are measured before and after with a haze meter that measures the scattering of light though the film. The arithmetic mean of the haze level of the three specimens to be tested shall not exceed 1.0%
ANSI Z26.1 Test #19 - Chemical Resistance (Nonstressed)
The purpose of the test is to determine whether non-stressed transparent plastic or glass and plastic glazing materials have a certain minimum resistance to the following chemicals which are likely to be used for cleaning purposes in motor vehicle service:
(1) One percent solution of nonabrasive soap in deioinized water (i.e., potassium oleate or equivalent)
(2) Kerosene No. K- I or K-218
(3) Undiluted denatured alcohol (Formula SD No. 30)
(5) An aqueous solution of isopropanol and a glycol ether solvent, and ammonium hydroxide in a concentration of 3% + 1%, simulating a commercial windshield cleaner.
Specimens shall be completely immersed in the fluid being tested, held for 1 minute, removed, immediately wiped with absorbent cotton, and examined for evidence of softened or tacky surfaces. There shall be no tackiness, crazing, or visible loss of transparency in the specimens as a result of chemical immersion.
ANSI Z26.1 Test #28 - Resistance to Temperature Change
The purpose of this test is to determine whether or not the glazing material is capable of withstanding changes in temperature. Samples are cycled from -49F for 6 hrs, then 71F for 1 hour, then 158F for 3 hours, then 70F until the panel temperature is equalized. The glazing specimens shall show no evidence of cracking, clouding, delaminating, or other visible deterioration.
ANSI (Z97.1) & CPSC impact testing of organic coated glazing
This test is for identifying the safety properties of safety glazing materials (glazing materials designed to promote safety and reduce the likelihood of cutting and piercing injuries when the glazing materials are broken by human contact) as used for all building and architectural purposes.
The test is conducted with an impacting object ( 100 lb bag filled with lead shot), suspended from an overhead support, Each specimen is struck only once at the center with the impacting object swinging in a pendulum arc from a drop height of 18 and or 48 inches above the horizontal centerline of the specimen. The specimen is evaluated such that it be judged to have been satisfactorily met if any one of the following safety criteria is met by each of the four specimens tested:
Type 1 “no tear or shear or opening develops within the vertical specimen through with a 3.0 in diameter sphere can pass”; for Type 2 “the 10 largest crack-free particles shall be selected and weighed… the average thickness will be used to determine the maximum allowable weight”; for Type 3 “the stiffness and hardness of the specimen shall be determined (Modulus of Elasticity and Rockwell hardness)”; for Type 4 “No breakage occurs.”
ASTM E84 Surface Burning (includes substrate)
Film is subject to burning conditions in a designated tunnel. The test method measures flame growth on the underside of a horizontal test specimen. The test is used to describe the surface burning characteristics of building materials, with the results classified into one of three tiered categories.
ASTM E162 -Flammability of a Radiant Heat Source
The test is conducted within a specified test chamber with the film sample angled and adjacent to a steadily burning heat source. The test is designed to learn how flames can spread across a material in environments like a real fire. The result is a radiant panel index value.
ASTM E662 - Smoke Density (optical density of smoke)
This test is designed to measure the optical density of smoke generated as the test film is subject to burning conditions. The results are expressed in terms of a specific optical density factor derived from measurements of an attenuated light beam in the test chamber during the film burn.
ASTM D882 Tensile Properties
This is a test of thin plastics or films, and measures the force required to break a specimen of film and the extent to which the specimen stretches or elongates to that breaking point.
ASTM D1308 Effect of Chemicals - spot test (Hydrofluoric Acid)
Is a test designed to determine the effect of chemicals on organic finishes. In this case Hydroflouric acid (a commonly used graffiti agent), on Graffiti Shield anti graffiti films. The effects are observed uncovered for specific time with time duration ranging from minutes to several hours.
ASTM D3330 90º Peel Adhesion
This test is used to determine the adhesive strength of pressure sensitive tapes and films. The test uses and apparatus that peels and measures the resistance of the film to a 90 degree angle of the test panel for a specified distance.
ASTM D5116 - Small Scale Environmental Chamber Determination of Organic Emissions from Indoor Materials and Products
This is a test to determine volatile organic compounds (VOC’s) from indoor materials and products, and is carried out using a small scale environmental chamber for 72 hours. Gas samples are collected and analyzed for concentrations of VOC’s including low molecular weight aldehydes and ketones.
FMVSS 302 - Flammability of Interior Materials
This test is designed to relate to the burning behavior of materials used inside motor vehicles. The test sample is exposed to a flame for 15 seconds within a combustion chamber in order to see when and if the flame extinguishes and also the time taken for the flame to pass a defined distance. The burn rate is then calculated.
Bombardier SMP 800c - Toxicity of Smoke
This test is designed to determine if and what concentrations of a toxic gas are produced during a test combustion. The test method is used to analyze smoke toxicity in an enclosed environment. During the test, smoke is analyzed using an FTIR (infrared spectroscopy) instrument for specific toxic elements, and reported in a tabulated format.
Long Term Heat Cycle
GSTM 5.10 is a test that analyzes the long term effect of elevated ambient temperatures on film applied to a sub-strait (i.e. glazing, stainless, etc.). The test qualifies the edge quality over time along with reviewing any discoloration that may happen.
