Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1
3、 This specification covers a lubricant suitable for facili-tating the insertion and positioning of preformed elastomericcompression seals in prepared voids (usually contractionjoints) in concrete pavement.1.2 The requirements of the lubricant are based on theperformance of the lubricant as measured
4、by its solids content,homogeneity, consistency, and drying rate.1.3 The values stated in inch-pound units are to be regardedas the standard. The metric equivalents of U.S. customary unitsmay be approximate.1.4 The following precautionary caveat pertains only to thetest method portion, Section 7 of t

10、-g load is applied in shear. A similarbond prepared after 20-min drying time shall remain un-separated for a minimum of 10 s when a 50-g load is appliedin shear.5. Basis of Purchase5.1 Each lot of lubricant shall be accompanied by themanufacturers certified test results attesting compliance withthis
11、 specification, unless an alternative agreement is concludedby the manufacturer and the purchaser.6. Sampling6.1 The lubricant samples shall be a 1-quart (1-litre) aliquotconsisting of a composite taken when possible from three ormore separate containers chosen at random. Samples also shallbe taken
12、from containers which appear to be nonrepresentativeand shall be tested separately. Before a sample is withdrawn,the contents in the container shall be mixed to uniformconsistency. The sample shall be placed immediately in anairtight glass jar or metal can until tested.1This specification is under t

16、e Decision on Principles for theDevelopment of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.17. Test Methods7.1 HomogeneityStir the test sample by hand for 2 minwith a spatula. Withdraw the spatula and examine
17、the lubricantas it flows from the spatula for lumps or agglomerates.Particles smaller in diameter than 0.015 in. (0.38 mm) shall notbe considered cause for rejection.NOTE 1At the consumers request, compliance with the 0.015-in.(0.38-mm) requirement shall be determined by a sample diluted 1+4 withXyl
18、ene through a 40-mesh sieve.7.2 Solids ContentDetermine in accordance with MethodA of Test Methods D1644.7.3 ConsistencyDetermine in accordance with Method Bof Test Methods D1084.

20、n. (3 by 25 by 50mm).7.4.2 Procedure:7.4.2.1 Condition the lubricant for at least3hat73.4 63.6 F (23 6 2 C).Apply a series of 2 in. wide (wet thickness)(14 6 2.5-mils) 0.356 6 0.064-mm films of the lubricant tofour separate nonabsorbent paper surfaces. A film applicator asspecified in 7.4.1.1 has be
21、en found to produce a wet film in thespecified range with this class of materials, but the depositedfilm thickness from any specific spreader and lubricant systemshould be checked to determine the conformance to thespecified thickness. Films should be at least 4 in. (100 mm)long, centered on the pap
22、er and parallel to the long axis of thesheet. Allow to dry in a horizontal position in a draft-free area.The time upon completion of the casting of the second film ofeach pair cast is recorded as the initial drying time for that pairof films.7.4.2.2 After several minutes drying, cut off at least 112
23、 in.(40 mm) from the bottom of the cast films and discard. Afterdrying 8 min, overlap the cut edges of the first pair 1 in. andplace face-to-face to form a 1 by 2-in. area lap shear bond.Take care to align the two films so that a force applied alongtheir center lines will impose a direct shear force
24、 without atwisting movement. Form the bond by placing the overlappedpapers on a horizontal smooth surface, placing a18-in. thick, 1by 2-in. aluminum plate over the bond area, and placing a500-g laboratory weight on this plate for 10 s. Hang the bondedpieces immediately in a vertical position and att
25、ach a 50-gweight with a small loop of wire, weighing less than 1 g, to thelower piece of paperboard forming the bond. Align the point ofsupport and the point of attachment for the weight on the centerlines of the cast films.7.4.2.3 Record the time needed for the 50-g load to com-pletely separate the
26、 bonded pieces with the aid of a stopwatch.If separation is not complete in 1 min, discontinue the test andrecord the separation time as more than 1 min.7.4.2.4 Repeat the above procedure with a pair of cast filmswhich are allowed to dry for 20 min before forming a bond.7.4.2.5 Testing should be con
27、ducted at 73.4 6 3.6 F (23 61 C) and at a relative humidity of 50 6 5%.8.
