ASTM D4059 GC for PCBs in Insulating Liquids
KN-4059 GC for PCBs in Insulating Liquids conforms to ASTM D4059 Standard Test Method for Analysis of Polychlorinated Biphenyls in Insulating Liquids by Gas Chromatography. This test method describes a quantitative determination of the concentration of polychlorinated biphenyls (PCBs) in electrical insulating liquids by gas chromatography. It also applies to the determination of PCB present in mixtures known as askarels, used as electrical insulating liquids.

ASTM D1177 Automatic Freezing Point Of Aqueous Engine Coolants
This tester involves the determination of the time-temperature curve prior to freezing and the determination of the horizontal or flattened portion of the freezing curve. The freezing point is taken as the intersection of projections of the cooling curve and the freezing curve. If the solution supercools, the freezing point is the maximum temperature reached after super cooling

ISO 6617 Ageing Characteristics Tester
The oxidation stability test of mineral transformer oils is a method for assessing the amount of sludge and acid products formed in a transformer oil when the oil is tested under prescribed conditions. Good oxidation stability is necessary in order to maximize the service life of the oil by minimizing the formation of sludge and acid.

ASTM D4340 Corrosion Of Cast Aluminum Alloys In Engine Coolants
It is essential that engine coolants prevent heat-transfer corrosion of aluminum cylinder heads during engine operation. Any corrosion products formed may deposit on interior radiator surfaces, reducing heat-transfer efficiency of the radiator. Overheating and boil-over of the cooling system may then occur
