INTERNATIONAL

Standard Specification forTufted and Woven Broadloom Carpet Adhesives WithoutHomogenous PVC or Non-PVC Backings 1

This standard is. isslt~d under the fixed designation D7799; the number immediately following the designation indicates the year oforiginal adoption or, III the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope1.1 This speci fication establishes mnnmum requirements

for adhesives used for the installation of tufted or wovenbroadloom carpet, within a climate controlled structure, whenadhered directly, and permanently, to a structurally sound andrecommended substrate.

1.2 This specification will provide the means to determineadhesive bonding variation as a result of different carpetbacking systems and their usage classifications based on thetraffic conditions they are subjected to.

1.3 This specification is not applicable to specialty adhe-sives such as those necessary for PVC and Non-PVC backedcarpet tile and broadloom where the backing would be consid-ered homogenous in nature.

1.4 The values stated in inch-pound units are to be regardedas standard, The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.

1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of tlze user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

5. Ordering Information

5.1 Ordering quantities, lot sizes minimum and maximum,along with packaging availability, container size, etc., shall bedetermined by the adhesive manufacturer and/or end user andmay be subject to industry standards. Currently the floorcovering industry has found the standard packaging as follows:one (1) quart, one (1) gallon. four (4) gallon containers.

6. Standard Conditioning6.1 Conditioning ill Air-Condition the specimens for

physical tests in air maintained at 73.4 ± 3.6°F (23 ± 2°C) and50 :!: 5 % relative humidity for not less than 3 h before testing.

7. Chemical Composition7.1 The adhesive shall contain no reportable quantities of

hazardous ingredients as specified by OSHA Regulations 29CFR 1910-1200.

7.2 The adhesive shall contain no toxic chemical subject toreporting requirement of Section 313 of Tille III of SuperfundAmendments and Reauthorization Act of 1986 and of 40 CFR372.

7.3 The adhesive shall not be reportable as a carcinogen asspecified by IARe, OSHA, NTP.

8.2 The initial viscosity of the adhesive shall be determinedby Test Methods 01084 or 02556 as appropriate and recorded.

9. Performance Requirements

9.1 The adhesive shall be freeze thaw stable when tested inaccordance with Practice D7149. The allowable change fromthe initial viscosity to the freeze cycling completion shall notexceed a :t 10 % difference. The adhesive shall maintain itsoriginal integrity and exhibit a smooth consistency, free ofclumps when stirred. The adhesive shall not exhibit a stringycondition. The test temperature and compliance statement shallbe listed on the container label.

9.3 When tested in accordance with Practice D7532 thereshall be no more than a 10 % loss in peel strength after 24 hthan from initial test result.

9.4 Accelerated aging after exposure to heat.9.4.1 Prepare additional sets of test specimens as outlined in

Test Methods D6004 and 06862.9.4.2 Utilizing the equipment and protocol in Test Method

F2199 condition then place the shear and peel specimens in theoven as described for a period of two weeks at 120°F. TheProcedure Sections 8.3, 8.4, 8.5, and 8.8 of Test Method F2 J99are not applicabJe since those sections are specific for themeasurement of tile.

9.4.3 Sections 9 (Calculation) and 10 (Precautions) of TestMethod F2199 are also to be ignored and replaced by shear andpeel tests as outlined in their respective documents.

9.4.4 There shall be no more of a loss in adhesion of 10 %based on the initial results as obtained.

NOTE 2-An accelerated aging test through exposure to heat specific toadhesives is under development.

NOTE 3- There may be instances where duration of the test may belengthened if felt necessary.

10. Sampling

10.1 Take a 2-qt (2-L) sample of adhesive that is represen-tative of the lot to be tested. Place l-qt (l-L) of the adhesivein a wide-mouth glass or stainless steel container and sealtightly. Use for all the tests with the exception of freeze-thawstability, Practice D7149, and storage life, Practice D1337. Forthe initial test only, to provide samples for testing these twoproperties, divide the second l-qt (l-L) equally and use halffor the freeze-thaw stability and half for storage life. Refer to9.1 for the acceptability criteria for freeze-thaw stability.
