16、tenance does of SCAin accordance with the engine manufacturersrecommendations, and those on the product label, shall besuitable for use in a properly maintained cooling system innormal service for a minimum of two years (See AppendixX1).5. Additional Requirements5.1 The coolant concentrate or predil

Hot surfaces typicallyare within the engine head, head spacer, upper cylinder liner, orliquid cooled exhaust manifold.

18、ASTM has test methods underdevelopment for both cavitation corrosion and hot surfacescaling. Until these procedures are approved as ASTMstandards, the mandatory requirements of Annex A1 shallapply.5.2 Both the concentrated and prediluted coolants shallcontain less than 50 g/g sulfate ion.6.

Certain additives (polyacrylate and othertypes) minimize the deposition of calcium and magnesiumcompoun
