1、Designation: D7799 12aStandard Specification forTufted and Woven Broadloom Carpet Adhesives WithoutHomogenous PVC or Non-PVC Backings1This standard is issued under the fixed designation D7799; the number immediately following the designation indicates the year oforiginal adoption or, in the case of
2、revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification establishes minimum requirementsfor adhesives used for the installation of tu
3、fted 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
4、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
5、 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
6、is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Ordering Information5
19、.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
20、 (1) quart, one (1) gallon, four (4) gallon containers.6. Standard Conditioning6.1 Conditioning in AirCondition the specimens forphysical tests in air maintained at 73.4 6 3.6F (23 6 2C) and50 6 5 % relative humidity for not less than 3 h before testing.7. Chemical Composition7.1 The adhesive shall
21、contain no reportable quantities ofhazardous ingredients as specified by OSHA Regulations 29CFR 19101200.7.2 The adhesive shall contain no toxic chemical subject toreporting requirement of Section 313 of Title III of SuperfundAmendments and Reauthorization Act of 1986 and of 40 CFR372.7.3 The adhesi
22、ve shall not be reportable as a carcinogen asspecified by IARC, OSHA, NTP.IARC = International Agency for Research on CancerNTP = National Toxicology ProgramOSHA = Occupational Safety and Health Administration7.4 The adhesive shall identify if natural latex is utilizedwithin the formulation.8. Physi
23、cal Properties8.1 The adhesive shall be of a consistency free of lumps ofa smooth homogeneous consistency when stirred or troweled,applied to surface.8.2 The initial viscosity of the adhesive shall be determinedby Test Methods D1084 or D2556 as appropriate and recorded.9. Performance Requirements9.1
24、 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 610 % difference. The adhesive shall maintain itsoriginal integrity and exhibit a smooth consistency, free ofclump

The test temperature and compliance statement shallbe listed on the container label.9.2 Table 1 identifies the minimum requirements for com-pliance with the specific usage class and the corresponding testmethods.9.3 When tested in ac
26、cordance 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 inTest Methods D6004 and D6862.9.4.2 Utilizing the equipment and proto
27、col in Test MethodF2199 condition then place the shear and peel specimens in theoven as described for a period of two weeks at 120F. TheProcedure Sections 8.3, 8.4, 8.5, and 8.8 of Test Method F2199are not applicable since those sections are specific for themeasurement of tile.9.4.3 Sections 9 (Calc
28、ulation) 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 1An accelerated aging test through exposure t
29、o heat specific toadhesives is under development.NOTE 2There may be instances where duration of the test may belengthened if felt necessary.10. Sampling10.1 Take a 2qt (2L) sample of adhesive that is represen-tative of the lot to be tested. Place 1qt (1L) of the adhesivein a wide-mouth glass or stai
30、nless 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 1qt (1L) equally and use halffor the freeze-thaw
31、stability and half for storage life. Refer to9.1 for the acceptability criteria for freeze-thaw stability.TABLE 1 Performance Tests and RequirementsTest Method Class 1 Class 2 Class 3ASTM D6862(90 Peel)$25 psi $20 psi $12 psiASTM D6004(180 Shear)$30 psi $20 psi $12 psiASTM D6962 orISO 4918 CastorCha
