NB/SH/T 0210-2022 in English

The industry standard NB/SH/T 0210-2022, titled "Hydraulic Oil Filterability Test Method," was issued on May 13, 2022, and came into effect on November 13, 2022. This standard specifies the procedure for evaluating the filterability of hydraulic oils, which is a critical parameter for ensuring the performance and longevity of hydraulic systems. The test method outlined in this standard is designed to assess the ease with which hydraulic oil can pass through a filter medium without causing excessive clogging or pressure drop.

The standard provides detailed guidelines on the preparation of the oil sample, the selection and preparation of the filter medium, and the conditions under which the test should be conducted. It includes specific requirements for the test apparatus, such as the filter holder, pressure gauge, and flow rate control, to ensure consistent and reliable results. The test results are expressed in terms of the filterability index, which quantifies the oil's ability to pass through the filter medium under specified conditions.

This standard is particularly important for the hydraulic oil industry, as it helps manufacturers and users to evaluate the performance of hydraulic oils in real-world applications. By adhering to this standard, stakeholders can ensure that the hydraulic oils they produce or use meet the necessary quality and performance criteria, thereby reducing the risk of system failures and maintenance costs.
