2、vision, 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.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specificati

6、 Testing Stop-Leak Additives forEngine Coolants3. Performance Requirements3.1 The following performance requirements of stop-leakadditives must be achieved in order to meet this specification.3.2 The stop-leak additive must be capable of plugging aminimum hole size of 0.254 mm (0.010 in.) and a mini
7、mumslot size of 12.7 mm (0.50 in.) long by 0.254 mm (0.010 in.)wide when tested in accordance with Test Method D 3147.3.3 The stop-leak additive must not plug a slot size largerthan 12.7 mm (0.50 in.) long by 0.635 mm (0.025 in.) wide.3.4 Fluid removed from the Test Method D 3147 stop-leaktest must
8、not leave any residue or particulate matter on thesurface of an ASTM E-11 No. 10 sieve, when poured throughthe sieve.3.5 Stop-leak additives passing the tests detailed above mustbe tested for foaming tendency in accordance with the TestMethod D 1881. A volume of 150-mL maximum foam isallowable with
9、a break time of 5 s max. The foam test must berun on fluid removed from the apparatus used, at the comple-tion of the Test Method D 3147 stop-leak test.3.6 Duplicate test runs must be conducted for each stop-leakadditive tested. Both sets of results are to be reported. Both setsof results must satis
10、fy all the requirements outlined in thisspecification.4. General Requirements4.1 Testing shall be performed according to the methodsdesignated in Test Methods D 1881 and D 3147. Follow TestMethod D 1176 for sampling and preparation of coolantdilutions.4.2 The minimum hole and slot plugging requireme
11、nts mustbe achieved in each of the duplicate tests required.4.3 The stop-leak additive, when installed in a vehiclecooling system in accordance with manufacturers recommen-dations and those on the product label, shall be suitable for usein a properly maintained cooling system without adverselyaffect
