The special reference liquid (A, B fluid) for high-speed reciprocating tester for evaluation of diesel lubricating property was developed and produced by Beijing Chaoyang Hi-Tech Applied Technology Research Institute Co., Ltd. The reference solution is used for the evaluation and evaluation of the instrument operation status of the high-frequency reciprocating tester for evaluation of the diesel lubricity; the reference solution is configured by various diesel components, without any lubricity improver and additive, and the components are stable. Requires preservation to not produce decay.
At present, the diesel lubricity high-frequency reciprocating testing machine manufactured by our company has sold more than 150 units in China. The customers include the China Petroleum Refinery Factory and provincial sales company central laboratory, Sinopec refinery and provincial sales company center laboratory, and local Oil refinery and national oil product inspection center, provincial and municipal quality inspection institute, and so on. All of the above users used the reference liquid produced by our company to check the performance of the instrument, and the product was well received.

specifications, preservation and use
1, a single bottle of reference solution is 500ml / bottle, a total of 2 bottles (A, B each a bottle of liquid)
2. The reference solution should be stored in a light-proof fresh cabinet at a storage temperature of 4 °C ± 2 °C.
3. Before the user uses the reference solution, remove the reference solution from the fresh-keeping cabinet. Hold it for 10 minutes to make the temperature of the reference solution agree with the room temperature. After shaking, take the middle-layer sample for testing.
4, shelf life: according to ISO 12156.1-2016 product shelf life of one year.
