The instrument complies with the ISO 12156.1 and ASTM D6079 standard test methods.
The CMS-01A High-frequency reciprocating rig (HFRR) for assessment of diesel fuel lubricity, standard test articles (balls and pieces) and standard reference fluid used for tester calibration are designed, researched and manufactured by the Company independently. This product has been delivered in batch to many oil refineries, quality supervision and inspection authorities, scientific research institutes and other organizations, and been well received by the users. The CMS-01A tester has improved the control accuracy of exciter stroke, and solved the periodic stroke calibration difficulty of imported tester; meanwhile, the air conditions in the test cabinet is controlled automatically in accordance with the allowable environment temperature and humidity range stipulated in the standard ISO 12156.1, which has solved the difficulty of other tester that the environment temperature and humidity are hard to control accurately, and the disturbance if any cannot be intervened at real time. Moreover, many other features have been improved technically, including tester base structure, connecting mode of exciter shaft lever, installation mode of lower test piece(test plate), clamp structure of upper test piece(test ball), control system, software operation interface, oil temperature control strategy, test parameter online monitoring, test data real-time storage and digital microscope measuring system so this product is much easier, convenient and efficient to operate.
This tester is designed pursuant to the test indexes stipulated in the standard the test method requirements ISO 12156-1, and the test conditions for evaluating the diesel fuel lubricity, and reach the international advanced level. This tester has obtained the utility model patent certificate at No. ZL2008 2 0127486.5 issued by the State Intellectual Property Office, and been tested by the national analytical instrument quality supervision and inspection center and appraised by the Expert Team of China Instruments Manufacturers Association. To ensure the accuracy and validity of data, the metering instrument needing calibration is provided with the calibration certificate issued by the qualified national authority when the equipment leaves the factory.
Now, the CMS-01A High-frequency reciprocating rig (HFRR) for assessment of diesel fuel lubricity is the most advantageous version among the technical improvement and upgrade of products of same kind in the world. The automatic constant temperature and humidity control system was first proposed and applied in the High-frequency reciprocating rig (HFRR) for assessment of diesel fuel lubricity by the Company, and has obtained the national patents at No. ZL2012 20533766.2 (semiconductor refrigeration) and No. ZL2013 20497422.5 (compressor refrigeration). This technology and other technologies such as reflective grating ruler for stroke control have represented that our technology in the field of High-frequency reciprocating rig (HFRR) for assessment of diesel fuel lubricity is ahead of domestic and foreign products of same kind.
In order to match the execution of the revised international standard ISO 12156.1、ASTM D6079,, we entrusted the Machinery Industry Analytical Instrument Quality Supervision and Testing Centre of China to perform the comprehensive analytical inspection and test on our CMS-01A tester, in accordance with each requirements of standard ISO 12156-1. The test results have proven that our product completely meets the requirements of ISO 12156-1 and can well control the test air condition, and the test repeatability and reproducibility are obviously lower than the range stipulated in the standard.
