ASTM D6754/D6754M-15(2022)

Standard Specification for Ketone Ethylene Ester Based Sheet Roofing

SCOPE
1.1 This specification covers flexible sheet made from ketone ethylene ester (KEE) as the primary polymer intended for use in single-ply roofing membrane exposed to the weather. The sheet shall be reinforced with fabric.  
1.2 In-place roof system design criteria, such as fire resistance, field-seaming strength, material compatibility, uplift resistance, in-situ shrinkage, among others, are factors that must be considered but are beyond the scope of this specification.  
1.3 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.  
1.4 The following precautionary caveat pertains to the test methods portion only, Section 8, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions—Terminology D1079 shall apply to this specification.
3.2 ketone ethylene ester (KEE), n—a high molecular weight thermoplastic copolymer of ethylene, containing carbon monoxide
and either vinyl acetate or acrylate monomer which are incorporated to provide softness and polarity.
3.2.1 Discussion—
Ester groups of the vinyl acetate or acrylate are pendant from the ethylene backbone and reduce crystallinity, which provides
flexibility. Carbon monoxide groups within the polymer backbone provide polarity. The KEE polymer is therefore a flexible
polymer, which is miscible with other polymers of similar polarity.
3.3 polymer content, n—in this specification, polymer content shall be defined as polymeric materials which are in the solid state
at room temperature, and are high (greater than 50 000 Mw) in molecular weight. Other ingredients, known to the art of polymer
compounding, such as certain waxes, stabilizers, and other additives, while polymeric in nature are not considered to be part of
the base polymer system.
4. Materials and Manufacture
4.1 The sheet shall be formulated from the appropriate polymers and other compounding ingredients. The KEE polymer shall be
a minimum of 50 % by weight of the polymer content of the sheet.
4.2 The sheet shall be reinforced internally with a fabric.
4.3 To make seam and repairs, the sheet shall be capable of being bonded watertight to itself during the design service life of the
sheets. The manufacturer shall recommend a suitable method. Design service life is defined as the designated time period of
intended system performance.
5. Physical Properties
5.1 The sheet shall conform to the physical requirements prescribed in Table 1.
5.2 The tolerance for time conditions (aging, weathering, and so forth) is 615 min or 61 % of the period, whichever is greater,
unless specified.
5.3 The tolerance for temperature conditions (aging, weathering, and so forth) is 62°C [4°F]62 °C [4 °F] of the specified
temperature, unless otherwise specified.
6. Dimensions and Permissible Variations
6.1 The width and length of the sheet shall be agreed upon between the purchaser and the supplier as part of the purchase contract.
The width and length tolerance shall be +3 % -0 %–0 % after permitting the sheet to relax 1 h at 23 6 1°C1 °C [73 6 2°F].2 °F].
6.2 The thickness and thickness tolerance shall be agreed upon between the purchaser and supplier as part of the purchase contract,
subject to the minimum requirement in Table 1.
7. Workmanship, Finish, and Appearance
7.1 The sheet, including factory seams if present, shall be watertight and be visually free of pinholes, particles of foreign matter,
undispersed raw materials, protruding reinforcement, and other manufacturing defects that might affect serviceability.
7.2 The sheet shall be visually free of nicks and cuts, voids, thin areas, delaminations, moisture-bound fabric, or other defects.
