ACT Performance Guidelines

TEXTILES GLOSSARY

The Association for Contract Textiles (ACT) is a not-for-profit trade association made up of textile wholesalers to the contract interior market, furniture manufacturers, and industry partners. ACT has developed Performance Guidelines represented by five symbols, which give architects, designers, and end-users a vast amount of information in a succinct, visual way. Member companies display these symbols on textile samplings to assure that fabrics perform up to contract standards and pass all applicable testing.

The five categories below describe a textile's performance features as measured by specified methods under standard laboratory conditions. A brief description of each category is followed by the test method used for each type of material and the required standard. For more comprehensive information, visit the ACT website at contracttextiles.org.

Abrasion

The surface wear of a fabric caused by rubbing or contact with another fabric. The ACT thresholds for acceptable abrasion results for Woven Upholstery Fabrics are:

Low Traffic/Private Spaces—15,000 double rubs, Wyzenbeek method (ASTM D4157); 20,000 cycles, Martindale method (ASTM D4966)

High Traffic/Public Spaces—30,000 double rubs, Wyzenbeek method (ASTM D4157); 40,000 cycles, Martindale method (ASTM D4966)

The thresholds for Coated Upholstery Fabrics are:

High Traffic/Public Spaces—50,000 double rubs, Wyzenbeek method (ASTM D4157)

Print Retention for Printed Coated Upholstery—Rating of 3 or higher using the ACT photographic scale of approved replicas (ASTM D3389)

End use examples of heavy-duty installations where upholstery fabrics rated at 30,000 double rubs should be appropriate are single shift corporate, hotel rooms/suites, conference rooms, and dining area usage.

ACT acknowledges that there are constant traffic/demanding spaces that may require higher levels of abrasion resistance. End use examples that may require higher than 30,000 double rubs include: 24-hour transportation terminals, 24-hour telemarketing, 24-hour healthcare emergency rooms, 24-hour casino gambling areas, and such public gathering places as theatres, stadiums, lecture halls and fast food restaurants.

The Wyzenbeek and Martindale tests are the two methods commonly used to predict wearability. Actual performance is determined by many factors such as fiber content, weaves, finishes, furniture design, maintenance, cleaning, and usage. Durability of an upholstery fabric is a complex interaction (combination) of performance tests that, in addition to abrasion, include seam slippage, pilling, tensile strength, and usage.

Due to misconceptions about Wyzenbeek test results being a reliable indicator of fabric lifespan, ACT has instituted a policy that licensees using the ACT Abrasion certification mark and publishing test results in excess of 100,000 double rubs are required to provide the following statement in their marketing materials: Multiple factors affect fabric durability and appearance retention, including end-user application and proper maintenance. Wyzenbeek results above 100,000 double rubs have not been shown to be a reliable indicator of increased fabric lifespan.


ACT Sustainability Certification

The ACT Environmental Committee surveyed existing sustainable textile standards and identified the need for a universal standard to better serve suppliers, distributors, and specifiers of textiles used in commercial interiors. As a result, ACT and GreenBlue partnered with NSF International to build a consensus-based standard, certified by the American National Standards Institute (ANSI). In 2011, ACT adopted NSF/ANSI 336 as its voluntary guideline for sustainability.

Facts Sustainability Rating
To recognize contract textiles that conform to this standard, ACT has introduced FactsTM, a sustainability rating that indicates that a fabric has been evaluated for environmental, economic, and social aspects across its life cycle. To earn the Facts certification mark, the textile must be assessed and verified by an independent third-party certification body authorized by ACT. Facts joins ACT's performance certification marks to convey complex information about sustainability.

Facts certified textiles must meet all of the prerequisites in NSF/ANSI 336. Once a textile achieves the Facts Compliant threshold, it can be designated as a Facts Silver, Gold, or Platinum rating by earning points for additional sustainability criteria. Facts assesses both the composition of textiles and how they are manufactured. Half of the evaluation focuses on fiber sourcing and safety of the material; the other half scrutinizes the manufacturing process, including water conservation, energy, air quality, recycling practices, and social accountability.

Additional Sustainability Standards
The Facts certification program covers criteria included in other industry-specific sustainability certifications including: Level® by the Business Institutional Furniture Manufacturers Association (BIFMA) and GreenSquared® by the Tile Council of North America (TCNA). ACT is pursuing strategic relationships with Leadership in Energy and Environmental Design (LEED), the Health Product Declaration (HPD) Collaborative, and other organizations to explore the possibilities of developing equal recognition programs for aspects of sustainability that overlap with Facts.


Textile Finishes

Bio-Pruf®—antimicrobial coating for vinyl performance upholstery that repels the growth of mold, mildew, bacteria, and odor-causing microbes.

Crypton Green®—engineered textile system that is moisture, stain, odor, and bacteria resistant with a moisture barrier integrated into the fabric. Certified to have a reduced environmental impact, Crypton Green upholstery textiles are made with recycled fibers, and do not contain toxic chemicals or VOCs.

Forbid SRT—proprietary topcoat that dramatically increases stain resistance while preserving the luster and softness for performance upholstery textiles. Tough stains such as ink, lipstick, mustard, and paint can easily be removed with this "anti-graffiti" finish.

Greenshield®—waterbased treatment that uses nano-particles to form a stain resistant, water repellent finish, while improving the hand/feel of woven textiles. Greenshield technology utilizes significanlty less fluorochemicals than other stain-resistant coatings, reducing its health and environmental impact, and improving recyclability and sustainability.


NSF/ANSI 336–2011

NSF/ANSI 336 is the principal standard used to evaluate and certify the sustainability of textiles used for commercial furnishings, over a product's entire life cycle. The Association for Contract Textiles (ACT) has been involved since the beginning of this effort, after identifying the need for a universal sustainability standard.

The standard addresses the environmental, economic, and social aspects of textiles used for commercial furnishings. Such fabrics can be woven, nonwoven, bonded, or knitted, and they can be used for upholstery (e.g., office and hotel furniture), vertical (e.g., drapery or panel systems) and decorative top-of-bed applications (e.g., bedspreads) in institutional, hospitality, and office settings.

Based on life cycle assessment principles, NSF/ANSI 336 employs an easy-to-use point system to evaluate textiles against established prerequisites, performance criteria, and quantifiable metrics in eight key areas:

1. Fiber Sourcing
2. Safety of Materials
3. Water Conservation
4. Water Quality
5. Energy
6. Recycling Practices
7. Air Quality in Manufacturing
8. Social Accountability

Certification to NSF/ANSI 336 is based on point totals, with the aim to achieve a Compliant, Silver, Gold, or Platinum level. As with all ANSI standards, organizations that choose to assess their products with this standard may achieve first-party, second-party, or third-party conformance:

First-party (self-declaration) assessment is performed by the person or organization that provides the product.

Second-party assessment is performed by the person or organization that has a user or purchaser interest in the product.

Third-party assessment is performed by a person or body that is independent of the person or organization that provides the product, and of the use or purchaser interests in that product.

The standard can also be used as a reference guide to sustainable production and "Design for the Environment" principles as they relate to commercial textiles. As a first- or second-party assessment, NSF/ANSI 336 can be met in whole or in part to internally benchmark increasingly sustainable practices or to measure the specific sustainable attributes of a product.
