Testing Services Include:
(Click on the buttons below for a full listing of capabilities)
 | Viscometrics (ASTM D7042) This test method covers the dynamic viscosity and density of liquids by Stabinger Viscometer (and the calculation of kinematic viscosity). |
| Viscosity Index (ASTM D2270) The high and low end temperature behavior of a lubricant based on a calculation of two different viscosities. |
| Specific Gravity (ASTM D1122) This test method covers the determination of the relative density of engine coolant concentrates and engine coolants. |
| Specific Gravity (ASTM D4052) This test method covers the determination of the density, relative density, and API Gravity of petroleum distillates and viscous oils that can be handled in a normal fashion as liquids at the temperature of test, utilizing either manual or automated sample injection equipment. |
| pH (ASTM D1287) This test method covers the determination of the pH of unused engine coolants and antirusts, and used or unused aqueous dilutions of the concentrated products. |
| Reserve Alkalinity (ASTM D1121) This test method covers the determination of the reserve alkalinity of new, unused engine coolants, and liquid antirusts as received, of used or unused aqueous dilutions of the concentrated materials, and of aqueous dilutions of solid antirusts. |
| Water Content (ASTM D1123) The Karl Fischer Reagent Method tests the water present in new or unused glycol-based coolant concentrates using a manual or an automatic coulometric titrator procedure. |
| Pour Point (ASTM 5949) The pour point of a liquid is the highest temperature at which it becomes semi solid and loses its flow characteristics. This test method covers the determination of pour point of petroleum products by an automatic instrument that applies a controlled burst of nitrogen gas onto the specimen surface while the specimen is being cooled and detects movement of the surface of the test specimen with an optical device. |
| Glassware Corrosion Test (ASTM D1384) Multi-metal corrosion test for copper, brass, solder, aluminum, steel, cast iron and cast aluminum. |
| Ion Chromatography (ASTM 5827) This test method covers the determination of chloride ion in engine coolants and other engine coolant solutions by ion chromatography. Tests inhibitors such as, but not limited to, nitrites, nitrates, phosphates, molybdates. Tests contaminates including glycol degradation, poor water quality and other sources of contamination. |
| Metal Content (ASTM D6130) This test method covers the determination of silicon in engine coolant by using a Microwave Plasma–Atomic Emission Spectrometer (MP-AES). This test method is applicable to the determination of dissolved or dispersed elements. Tests inhibitors including, but not limited to, corrosion metals and contamination. |
| High Performance Liquid Chromatography (HPLC) This test method checks for inhibitor levels as well as potential contamination. |
