Tarr Rating For Carpet
The carpet and rug institute cri developed a model that classifies carpet using a texture appearance retention rating tarr.
Tarr rating for carpet. This model is based on simulated wear tests and provides a rating for different levels of traffic. Severe which needs a carpet with tarr greater than or equal to 3 5. The density refers to the spacing of the fibers within the carpet backing. Ratings help to identify how well a particular carpet will preform in specific application.
Tarr tests a carpet s ability to remain tufted and retain its original shape after being properly installed and maintained in commercial setting. There are three basic categories for tarr based off of 12 000 cycle hexapod. The weight of the face fiber of the carpet is measured in ounces. A moderate heavy severe or special end use classification is established for each application based on the.
In addition to tarr keep in mind the density of the carpet. Moderate which needs a carpet with tarr greater than or equal to 2 5. These classifications categorize commercial carpet s ability based on anticipated frequency and intensity of foot traffic exposure. The cri recommends the following scale for tarr.
This is especially important because it ensures quality. Texture appearance retention ratings tarr help determine the right commercial carpet for specific areas of use. The tarr classification typically puts carpet tiles into one of three usage categories. Understand the classification and texture appearance retention rating tarr guidelines cri developed a model specification process that classifies areas of intended use and minimum carpeting texture appearance retention ratings tarr for particular areas of use.
Each category is designed to reflect a different level of foot traffic and use. Moderate 2 5 tarr. Density of carpet fibers. As a general rule the higher the end use rating of your chosen tile the more durable it is.
Heavy which needs a carpet with tarr greater than or equal to 3 0. Use and minimum carpeting texture appearance retention ratings tarr for particular areas of use. Tarr ratings are ranked as moderate heavy and severe.
