RAIL TRANSIT CAR CARPET SPECIFICATION

(Revised: April 17, 2014)

1.0 SCOPE:

1.1 Terminology:

Herein the following terminology applies for this carpet specification: The

"Authority" and "WMATA" refer to the Washington Metropolitan Area Transit

Authority. "Contract" refers to the agreement for supplying materials according to this specification. "Contractor" refers to the organization which is a candidate for fulfilling the Contract. "Vendor" refers to the manufacturer of the carpet which may or may not be the Contractor.

1.2 General:

1.2.1 This specification establishes the requirements for performance, design, testing requirements and qualifications of carpet material used by the Authority in its transit rail cars. There are generally four (4) different types of carpet which are used in the various car series.

1.2.2 It is important to state that the selection and approval of rail car carpet was conducted at the level of the Board of Directors of the

Washington Metropolitan Area Transit Authority. The carpeting, which is unique in North American transit rail cars, is viewed as an important statement of quality and commitment to exemplary service to the customer, which is not equaled by any other transit authority's equipment. In keeping with this commitment to the highest quality, the

Contractor shall submit the required carpet certifications, along with other contract documents, as a requirement for consideration of their bid package (See Section 4.0, Quality Assurance). The Contractor shall also submit proof of their capability in place to perform the required functions, as well as a proven background in producing / providing carpet to the Transit Industry.

1.3 Intended Use:

1.3.1 Function:

The carpet shall provide a durable, cleanable, and resilient walking surface. The carpet shall, in all respects, be suitable for the purpose intended.

Page 2 of 10 April 17, 2014

1.3.2 Location:

The carpet is intended to cover the upper surface of the floor in rail transit cars operated by the Authority in its Metrorail System in greater Washington, D.C., Suburban Maryland, and Northern

Virginia, USA.

1.3.3 Environment:

The carpet is intended to function in an environment which will have a temperature range from 0°F to 140°F at a maximum relative humidity of 100%, which will include heavy rain. During winter operations

(which may be experienced as much as 5 months a year) there will be numerous periods of constant ice and snow for several weeks at a time during which the carpet will be subject to de-icing materials such as rock salt, calcium carbonate, sodium nitrate, and other commercial deicers, as well as abrasive sand typically used to provide traction on icy surfaces. Additionally, the carpet will be exposed to runoff of caustic cleaning solutions used on other portions of the car.

2.0 APPLICABLE DOCUMENTS:

2.1 Industry Standards:

The following is a list of standards which will be used to evaluate or prepare the materials furnished for this specification. This list is not all-inclusive and may not show requirements listed elsewhere in this specification. All standards used shall be the latest revision available from the standard agency. If a standard has been discontinued or cancelled by the standard agency, the last revision released shall be used for purposes of this specification.
