Problems solved by technology
[0003] National standard GB 12981-2012 "Motor Vehicle Brake Fluid" appendix H specifies a method for testing the evaporation performance of brake fluid. After the specified amount of brake fluid is kept at 100°C for 168 hours, according to the quality change before and after the constant temperature, Calculate the mass fraction of evaporation loss. The test period under this test condition is too long to quickly measure the evaporation loss of brake fluid, which is difficult to meet the needs of rapid detection in scientific research and production.

[0065] In one embodiment, the step S12 by orthogonal test, according to the test range of factors, to obtain a plurality of test conditions, including the step of S121 ~ S122:
[0066] S121, according to the test range of factors, determining a plurality of test factors corresponding to the recommended test factors;
[0067] S122, orthogonal test, the test according to several factors corresponding to the recommended test factors, obtaining a plurality of test conditions.
[0068] Some Effects Test orthogonal test, corresponding to the various factors test; in particular, a number of factors recommended test according to a preset rule selected from the range of the test factors, and select the factors corresponding to the test factors recommended values are combined to obtain a number of test conditions. Wherein the selection rules may be set in advance the number of values, depending on the number and size range of values, determining a plurality of test factors extracted recom...

The invention discloses a method for determining evaporation loss determination test conditions, which comprises the following steps: analyzing at least two test influence factors of a known sample for evaporation loss determination by using a thermogravimetric analysis method, and determining the value range of the test influence factors; obtaining a plurality of test conditions by adopting an orthogonal test method according to the value range of the test influence factors; according to the pre-obtained evaporation loss result of the known sample, comparing and analyzing the test result of the evaporation loss measurement of the known sample under each test condition, and determining the optimal test condition. The invention further discloses a determination device and equipment for the evaporation loss determination test conditions and a storage medium, the test conditions for evaporation loss determination of a known sample can be analyzed by using a thermogravimetric analysis method and an orthogonal test, and then the optimal test conditions are determined, so that rapid determination of the evaporation loss of the brake fluid under the optimal test conditions is realized.
Description
Technical field [0001] The present invention relates to the field of measuring technology, particularly, it relates to a measurement test conditions for determining the evaporation loss of the methods, devices, and equipment. Background technique [0002] Braking performance was evaporated lubricity for brake fluid, and the normal life and reliability when used at higher temperatures of the braking system are of great significance, it is an important performance index of the brake fluid temperature. Evaporation loss of brake fluid failure, high temperatures generated during braking, brake fluid can cause a lot of evaporation, resulting in brake failure, severe brake fluid may even be completely evaporated, can not brake, causing serious accidents, direct harm to people's lives. Therefore, it is necessary to brake fluid loss by evaporation was measured, using the brake fluid has good high temperature stability and low evaporation loss.
