1. Scope
1.1 This specification covers thermoplastic fabrics such as polyester, polyester/polyamide bicomponent, or composites with fiberglass or polyester scrims that can be used during the construction of cold-applied roofing and waterproofing. 1.2 This specification is intended as a material specification. Issues regarding the suitability of specific roofconstructions or application techniques are beyond the scope of this specifica- tion. 1.3 The specified tests and property values used to charac- terize the respective fabrics are intended to establish minimum properties. In-place system design criteria or performance attributes are factors beyond the scope of this material speci- fication. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions—For definitions of terms used in this specification, refer to Terminologies D123 and D1079.
4. Classification
4.1 The thermoplastic fabrics covered by this specification are of the following general constructions and compositions. Each is a separate class or type differentiated by the polymer type, combination of polymers, manufacturing process, or some combination thereof. 4.1.1 Type I—Polyester spunbonded without resin, un- needled; 4.1.2 Type II—Polyester spunbonded without resin, needled; 4.1.3 Type III—Polyester mat plus fiber glass scrim with resin; 4.1.4 Type IV—Polyester core/polyamide sheath bicompo- nent spunbonded; 4.1.5 Type V—Polyester mat with polyester stitching; 4.1.6 Type VI—Polyester mat plus polyester scrim with resin; and 4.1.7 Type VII—Polyester scrim fabric with resin.
5. Materials and Manufacture
5.1 The fabric shall be a uniform, thin, porous mat of the primary thermoplastic polymer, with or without the addition of reinforcing stranded glass or thermoplastic yarns. Chemically bonding with a water-resistant resin or thermally bonding with other thermoplastic polymers shall be permitted.
15. Rejection and Resubmittal
15.1 Failure to Conform—Failure to conform to any of the requirements as stated in this specification constitutes grounds for rejection. 15.2 Rejection Redress—The supplier shall have the right to inspect the rejected materials. The supplier and the purchaser shall agree to the quantity of rolls deemed unacceptable. The supplier shall then have the right to submit the same number of new rolls as replacement.
16. Packaging and Package Marking
16.1 The rolls shall be wrapped or banded securely with a substantial grade ofpaper, plastic wrap, or taping that encircles the roll in a manner that will prevent slipping or unraveling. 16.2 No roll shall contain more than two pieces, and no more than 3 % of the rolls in any lot (pallet or shipment) shall contain two pieces. Pieces represent roll ends that can be one of the following: (1) individual and loose, (2) adhered, or (3) stitched to appear as one continuous piece. These rolls must be marked clearly with a red tag or other item to identify the location of the splice. 16.3 Unless otherwise specified, each package shall be marked plainly with the manufacturer’s or supplier’s name, product or brand name, or both, and theASTM designation and type.
