TEST METHOD QUESTIONS
ANSI A 326.3 calls for a series of tests in a specific location defined by its exposure to slip and fall hazards. A total of 12 data points is required to complete an ANSI A326.3 result. The BOT-3000E is programmed to take you through this test method step by step. (link)
Yes, sensor preparation is critical to accurate results. A contaminated sensor will invalidate the test. A326.3 defines specific sensor preparation steps and your BOT-3000E kit will include all of the tools you need.
Yes. Regan Scientific Instruments strongly recommends device verification at each site to be tested to ensure proper tribometer results. A simple verification procedure is included in your BOT-3000E kit and takes only seconds to complete.
SCOF is the force required to start an object moving: DCOF is the force required to keep an object moving. Most major research shows that DCOF is the better indicator of slip resistance.
SCOF and DCOF are physical properties that are measured the same way regardless of the device so long as that device has been designed to measure COF. Some devices were designed to measure other things such as energy loss and they use proprietary indexes to report their results. The American National Standard A326.3 requires a device that can measure COF.
ANSI A137.1 is a manufacturer's standard for ceramic tiles. ANSI A326.3 is a laboratory and field test method (dry or wet) for the DCOF of a pedestrian surface. ANSI A137.1 references the A326.3 method in its section on slip resistance.
SLS solution contains a small amount of sodium laurel sulfate mixed in with distilled water to create a surfactant to be used in wet testing. The purpose of this surfactant is to remove surface tension and ensure an evenly dispersed aqueous wet test path.
The BOT-3000E is programmed to conduct either wet or dry A326.3 tests and create reports as defined in that standard. In the manual mode the BOT-3000E can be used for any other chosen method including SCOF and DCOF.
The NIST traceable calibration for the BOT-3000E is once every 12 months and must be calibrated at the manufacturer's facility.
The BOT-3000E can test any distance between 4-36 inches. ANSI A326.3 calls for a test distance of 10 inches well within the capability of the BOT-3000E.
Yes the BOT-3000E can test the same surface either dry or wet.
Yes the BOT-3000E can be taken on an airplane, but must be checked due to its size.
PRE/POST AUDIT QUESTIONS
The BOT-3000E reports SCOF and DCOF results on a linear scale of 0.01-1.00 and is a relative indicator of the slip resistance of the surface. The ANSI A326.3 standard has identified a DCOF measurement value of 0.42 as the threshold for adequate slip resistance.
If an installed walkway surface cannot meet the 0.42 threshold for wet testing, the test can be repeated in the dry mode. If the surface meets the 0.42 threshold in the dry mode that walkway must be kept dry to be considered slip resistant. If the walkway is exposed to involuntary wetness, a friction increasing treatment should be considered.
