7、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 minimums
8、lot size of 12.7 mm(0.50 in.)long by 0.254 mm(0.010 in.)wide when tested in accordance with Test Method D3147.3.3 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 D3147 stop-leaktest must not leave any
9、 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 D1881.A volume of 150-mL maximum foam isallowable with a break time of 5
10、 s max.The foam test must berun on fluid removed from the apparatus used,at the comple-tion of the Test Method D3147 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 satisfy all the requirement
