1、Designation: D1874 62 (Reapproved 2010)Standard Specification forWater- or Solvent-Soluble Liquid Adhesives for AutomaticMachine Sealing of Top Flaps of Fiberboard ShippingCases1This standard is issued under the fixed designation D1874; the number immediately following the designation indicates the
2、year oforiginal adoption or, in the case of 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 covers starch, dextrin, casein, r
3、esinbase, and other liquid adhesives (excepting pressure-sensitivetypes) used for sealing the top flaps of fiberboard shippingcases. It includes provisions for adhesive selection based on:(1) satisfactory machining characteristics on specific equip-ment, and (2) adequate adhesion under specified sto
4、rageconditions. This specification further provides for the controlof uniformity between lots of an adhesive selected on the abovebases by limiting variations in nonvolatile content and viscos-ity.1.2 This specification provides bases for adhesive selectionas well as product uniformity control. Test
5、 methods arespecified for measuring (1) nonvolatile content, (2) consis-tency, and (3) bonding permanency under specified storageconditions.1.3 The values stated in acceptable metric units are to beregarded as the standard. The values given in parentheses areprovided for information purposes only.2.

Physical Properties4.1 The general consistency shall be uniform, and theadhesive shall be free of lumps and particles.4.2 The machining properties
8、 shall be such that the adhesive(when diluted in accordance with to the manufacturers instruc-tions) shall not string when machine transfer surfaces areseparated, shall not build up excessively on machine parts, andshall not foam.4.3 The bonding permanency of the adhesive shall providea minimum of 7
9、5 % paper fiber tear when tested under theexposure conditions specified in the contract or purchase order.The exposure conditions shall be selected from those in Table 1of Test Method D1581.5. Permissible Variations5.1 The nonvolatile content of the adhesive shall be within61.5 % of that specified i
10、n the contract or purchase order.5.2 The consistency of the adhesive shall be within 620 %of that specified in the contract or purchase order.6. Sampling6.1 The adhesive sample shall be a 0.9-L (1-qt) aliquotconsisting of a composite taken when possible from three ormore separate containers chosen a
11、t random. Samples also shallbe taken from containers that appear to be nonrepresentativeand shall be tested separately. Before a sample is withdrawn,mix the contents in the container to uniform consistency. Placethe sample immediately in an airtight glass jar until tested.6.2 Samples of adhesives us
12、ed on fiberboard cases shall beof the same type used on the production line. Samples ofboards used for all bonding permanency tests shall be within adefined range of water absorptiveness to eliminate this variablefrom the test.

Retest and Rejection9.1 If the results of any test do not conform to the require-ments prescribed in this specification, at the op
19、tion of themanufacturer, that test shall be repeated on two additional setsof specimens from the same lot of adhesive, each of whichshall conform to the requirements specified. If either of thesetwo additional sets of specimens fails, the lot or batch ofmaterial may be rejected at the option of the
