This method provides a protocol for testing the durability of detectable warning systems in a repeatable manner. Laboratory exposures and evaluation tests were developed to simulate the types of damage and degradation anticipated in service. Exposures are conducted cyclically to allow for effects of combined interaction of the simulated environmental exposures. Nondestructive evaluation tests are conducted both before and after exposures to provide comparative values. Destructive evaluation tests are conducted after the exposures.
The primary objective of this test method is to provide a repeatable set of tests that can be conducted specifically to evaluate durability of detectable warning systems. Each test is suitable for use with any type of detectable warning system, regardless of the material composition or method of attachment. Specimens are attached to concrete slabs to provide a test of the detectable warning system/sidewalk system. Data produced following this method is anticipated to be used for purposes of determining product durability and product comparison.
This method of test covers the specimen fabrication, testing protocols, and laboratory-accelerated weathering of detectable warning systems for the purposes of evaluating durability. This method of test covers the following categories:
- Non-Destructive Evaluation Tests
- Visual and Microscopic Evaluation
- Dome Shape and Geometry Measurement
- Slip Resistance Measurement
- Color Measurement
- Destructive Evaluation Tests
- Resistance to Impact from Falling Tup
- Resistant to Impact from Simulated Snowplow Blade (Cold Exposure)
- Wear Resistance
- Coating and Single Dome Bond (Systems with coatings or surface applied single domes)
- Laboratory Accelerated Weathering - Exposure Regime (Hot and Cold Exposure Categories)
- High Temperature Thermal Cycling
- Abrasion Exposure
- Freeze/Thaw Durability (Cold Exposure Applications only)
- Ultraviolet Light Exposure
