As a common part of DCOF testing (Dynamic Coefficient of Friction), testing for surface roughness of polished concrete floors and other floor types helps determine the traction and performance of the floor at the microscopic level that may help to prevent future issues and safety hazards. Gloss testing of floor surface finishes measures the levels of light reflection, DOI, and haze of the surface finish.
While complying with the project specifications is the most common purpose, verifying the quality and consistency of a finished floor provides value and peace of mind to contractor and owner alike. These tests will provide a measure of the reflectivity (gloss, haze and DOI) of the surface and the microscopic texture (roughness).
We can help create a plan to mitigate issues that arise from the gloss and surface roughness that affects light reflection, traction, and performance. Having this data can help maintain quality and hold contractors accountable. Having the data can also help in getting paid on a completed job. More recently, building owners of box store, warehouse and distribution centers big and small are among many of the professionals who benefit from Moore Engineering Services’ Surface Roughness and Gloss Testing services and consulting expertise.
Testing for surface roughness and gloss is nondestructive and can be done at anytime. If constructing a new building, we recommend testing after the flooring is completed and prior to bringing in any furnishings or equipment allowing for mitigation prior to final turnover.
Standards in the industry have long defined the tests necessary to measure gloss, haze, DOI, and surface qualities common in polished concrete and other floor types. Supported by ASTM D523 Standard Test Method for Specular Gloss and ASTM D2457 Standard Test Method for Specular Gloss of Plastic Films and Solid Plastics, we utilize the state-of-the-art Rhopoint IQ Gloss Haze & DOI Meter to quantify the reflective properties and characteristics of the floor. Typically this testing results in a gloss units of measurements and is specified by the angle of reflection desired. With the benefit of roughness meters, such as the Marsurf PS 10, we track and quantify the microscopic surface profile which can be reported in a number of calculated and standardized values such as Ra, Rz, and others as required.
