About this file
This document is an informational resource guide on carpet specifications for federal building projects, specifically addressing Texture Appearance Retention Rating (TARR) standards and their application.
The guide explains that the Office of Management and Budget (OBO) Design Guide establishes carpet performance standards based on traffic levels: Moderate traffic (≥2.5 TARR) for offices and examination rooms; Heavy traffic (≥3.0 TARR) for corridors, classrooms, and conference rooms; and Severe traffic (≥3.5 TARR) for airports, medical facilities, and transportation hubs. TARR, developed by the Carpet and Rug Institute through a 12,000-cycle hexapod wear simulation test, measures on a scale of 1-5 how well carpet retains its original appearance under foot traffic, with higher ratings indicating longer-lasting texture retention. The document notes that variables such as staining, maintenance, and installation quality are not reflected in TARR ratings, and that improper carpet selection for a space's traffic level can void manufacturer warranties and result in shortened carpet lifespan. The guide also references EN 1307 European carpet classification standards (classes 31-34 for commercial use) as an alternative specification method. An example product specification is provided: Anker Aera carpet, classified as EN 1307 class 33 - LC2, suitable for intensive commercial traffic applications.

Maybe not so helpful, but in case of a new building, they would use the OBO Design Guide standards
The OBO Design Guide talks about moderate, heavy and severs traffic.
Attached Pdf, page 11:
Moderate (≥ 2.5 TARR): Offices, examination rooms, areas with light foot traffic.
Heavy (≥ 3.0 TARR): Corridors, classrooms, conference rooms, libraries, military Housing Severe (≥ 3.5 TARR): Airports (and other transportation facilities), medical facilities, elevators, stairs, multipurpose areas
What Is A TARR Rating?
TARR (texture appearance retention rating) is meant to give you a better understanding of how well a specific carpet should perform in certain spaces based on the amount of foot traffic expected in that area. It measures the level of appearance change of a specific carpet after foot traffic.
In other words, the TARR will help you understand the durability and performance of the carpet you are specifying. For example, a low TARR-rated carpet in a high traffic area like a lobby or corridor might look plush when initially installed but will get crushed and wear down over time.
TARR is a third-party system developed by the Carpet and Rug Institute (CRI) through a consensus process involving technical experts in the carpet industry and commercial and government specifiers.
The ratings are established through simulation wear tests and are based on a 12,000-cycle hexapod exposure conditioning test. The simulation is performed by securing a carpet to a backing sheet that is mounted inside a rotatable drum with the pile surface of the carpet exposed.
A metal hexapod, with six polyurethane studs, rolls randomly on the pile surface inside the rotating drum for 12,000 revolutions.
The resulting change in appearance is rated on a numbered scale from 1 to 5, with 5 representing no change in appearance, and 1 representing a severe change.
The higher the TARR, the longer the carpet will retain its original appearance. For example, carpet with a
4.0 TARR will retain its original new texture appearance longer in various traffic conditions than carpet with a 3.0 rating.
These ratings take into account the total of the carpet and not just how the face fiber will perform, but they do not reflect any other variables such as staining, maintenance and poor installation.
Carpet backing can play a part in the overall TARR of carpet, as well. While it can make a small difference, industry tests have shown that cushion backing can absorb some of the impact from foot traffic leading to a longer lasting texture appearance.
There are three basic categories for TARR based off of 12,000 cycle hexapod:
1. Moderate, which needs a carpet with TARR greater than or equal to 2.5
2. Heavy, which needs a carpet with TARR greater than or equal to 3.0
3. Severe, which needs a carpet with TARR greater than or equal to 3.5
The Challenge of Measuring Foot Traffic Because all foot traffic is not equal, it is difficult to quantify foot traffic for these ratings. For example, foot traffic from workers wearing heavy boots is not the same as foot traffic from business shoes. And traffic in a casino or airport has more rolling loads and is in a more condensed period of time than, say, a small office building.
Therefore, CRI developed a fact sheet including a model specification process that categorizes areas of use and minimum TARR for each particular end-use, so that you know what type of TARR to use in each application.
Private offices, sleeping rooms, and some administrative areas are generally rated as moderate use, while conference rooms, open offices, and classrooms are generally rated as heavy use. Severe use is generally described as spaces such as corridors, entrances, and public areas. The traffic level application chart tells you the minimum rating you should look for in a carpet for that end-use.
While there can be variables that affect the end use and level of foot traffic, it is important to use the right TARR rating for the right end use. Using carpet that does not meet the minimum guidelines for your space can result in significant wear and a shortened life cycle of your investment.
Additionally, if you place a low TARR carpet in a heavy or severe traffic area, it is possible to void the manufacturer’s warranty. We would be remiss in not telling you that proper maintenance of your carpet can affect the lifespan of your carpet and its overall appearance throughout the lifecycle.

Heavy traffic is 1,000 to 10,000 traffics per day or up to 2,000,000 traffics for the life of the carpet.
