Scope*1.1 This specification covers the requirements for fully-formulated glycol base coolants for cooling systems of he
3、avy-duty engines. When concentrates are used at 40 to 60 % glycolconcentration by volume in water of suitable quality, (seeAppendix X1), or when prediluted glycol base engine coolants(50 volume % minimum) are used without further dilution,they will function effectively during both winter and summer
4、toprovide protection against corrosion, cavitation, freezing, andboiling.1.2 This specification is intended to cover the requirementsfor engine coolants prepared from virgin or recycled ethyleneor propylene glycol.NOTE 1Committee D15 has not substantially studied the impact ofusing recycled glycols

However, several serious cases of very poor perfor-mance have been reported and substantiated in heavy duty fleets when recycledglycols from sources such as above h

Additional Requirements4.1 The coolant concentrate or prediluted coolant addition-ally shall provide protection in operating engines againstcavitation corrosion (also termed liner pitting) and againstscaling of internal engine ho

A test procedure for compatibility (TestMethod D 5828) has been developed

Onesuch test has been developed.5A1.2 Several chemical compositions have been testedextensively by producers and users and satisfactorily minimizecylinder liner cavitation in actual test engines. Coolants meet-ing either of the following compositions are regarded aspassing the
24、requirements of A1.1:A1.2.1 A minimum concentration of nitrite (as NO2)of1200 g/g (ppm) in the 50 volume % predilute coolant, orA1.2.2 A minimum combined concentration of nitrite (asNO2) plus molybdate (as MoO42) in the 50 volume %predilute coolant of 780 g/g (ppm). At least 300 g/g (ppm)each of NO2

Certain additives (polyacrylate and othertypes) minimize the deposition of calcium and magnesiumcompounds on heat rejecting surfaces. No specific chemicalrequirements for hot surf

Water havinga high mineral content or corrosive materials is unfit forcooling system use.X1.1.1.2 When preparing coolant mixtures, the wa

In the absence ofspecific recommendations from the engine or vehicle manu-facture, see Table X1.1. Contact your local water department,the responsible government agency, or submit a water s

SCAs,however, do not extend the freeze protection provided by thecoolant concentrate.X1.1.4.2 Heavy-duty engine users experience has
34、shownthat compositions below those defined in Annex A1.2 may notprovide long term protection against cavitation corrosion (linerpitting). User experience and published information shows thepresence of nitrite in an SCA or fully-formulated heavy-dutycoolant is particularly effective in providing maxi
35、mum protec-tion.X1.1.4.3 New technology consisting of other chemistriesmay provide satisfactory protection. Such chemistries can beestablished by agreement between producers and users upondemonstration of performance. Such demonstrations can con-sist of comparative laboratory cavitation tests or com

An engine test has been devel-oped.5X1.2 Coolant Maintenance Recommendations:X1.2.1 If any of the following recommendations differ,follow the engi

38、pment, such as a refrac-tometer, to measure coolant concentrate levels for freezeprotections.X1.2.6 Use the SCA manufacturers recommended test kitwhen testing the coolant for proper additive concentration. Testkits shall indicate the degree of liner pitting protection presentin the coolant.X1.2.7 Ch
