ISO/TC 70/SC 7/WG 2 is a Subcommittee within the International Organization for Standardization (ISO). It is named "Review of the no-reproducibility of Round Robin filtration efficiency results". This committee has published 1 standards.
ISO/TC 70/SC 7/WG 2 develops ISO standards in the area of Information technology. Currently, there are 1 published standards from this subcommittee.
The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.
A Subcommittee (SC) in ISO operates under a Technical Committee and focuses on a specific subset of the TC's scope. Subcommittees develop standards and technical specifications in their specialized area, reporting to their parent Technical Committee. They may also have working groups for detailed technical work.
ISO 4548-12:2017 specifies a multi-pass filtration test with continuous contaminant injection and using the online particle counting method for evaluating the performance of full-flow lubricating oil filters for internal combustion engines. The scope of this document is limited to steady state conditions and does not address fluctuations in the flow rate. The test procedure determines the contaminant capacity of a filter, its particulate removal characteristics and differential pressure. This test is intended for application to filter elements with an efficiency of less than 99 % at particle size greater than 10 μm. NOTE Several test flow loops built into one test rig, or several test rigs, would be necessary to cover the complete flow range of 2 l/min to 600 l/min.
