ISO/TC 70/SC 7 - Tests for lubricating oil filters

This document specifies a method of testing full‐flow lubricating oil filters for internal combustion engines to determine their ability to withstand a static pressure objective and to determine their burst pressure and the failure mode concerned. It does not apply to filters for use in aeronautical applications or plastic components.

This document specifies a method of testing the ability of full-flow lubricating oil filters manufactured with metal pressure vessel materials for internal combustion engines to withstand an internal pressure surge. Normally surges occur when an engine is started from cold, and cyclic internal pressure variations experienced during operation. These tests are intended for application to spin-on type filters and detachable filters with disposable elements. The tests can be applied to other filters, if thought applicable, by agreement between the filter manufacturer and the purchaser. NOTE This test is not intended to replace simulated environmental testing (e.g. at very low temperatures). If such testing is required, it will be the subject of negotiation between the supplier and customer.

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.

ISO 4548-14:2016 specifies a method of testing the ability of full-flow lubricating oil filters manufactured with composite pressure vessel materials for internal combustion engines to withstand an internal pressure surge and cyclic internal pressure variations experienced in the application at specified operating temperatures. These tests are intended for application to spin-on type filters and detachable filters with disposable elements constructed of composite materials.

ISO 4548-15:2014 specifies a method of testing the structural integrity of full-flow lubricating oil filters to withstand engine vibrations. This test is intended for application to spin-on type filters and detachable filters with disposable elements with a maximum flow rate of 100 L/min. Upon agreement between manufacturer and purchaser, this test method can be applied to filters with higher flow rates. This test method is intended for test parts made from composite materials that experience mechanical property changes within the temperature range experienced in service. The test can be applied to filters with other temperature sensitive materials if thought applicable by agreement between the filter manufacturer and the purchaser.

ISO 4548-13:2013 specifies a method of testing full-flow lubricating oil filters for internal combustion engines to determine their ability to withstand a static pressure objective at high and cold temperatures and to determine their burst pressure and the failure mode. It applies to all oil filters, for example spin-on ones and filters made of temperature sensitive materials. It applies to new filters and filters returned from endurance tests.

ISO 4548.7:2012 specifies a method of testing the constructional integrity of full-flow lubricating oil filters to withstand engine vibrations. This test is intended for application to spin-on type filters and detachable filters with disposable elements with a maximum flow rate of 100 l/min. This test method is intended for test parts made from materials that do not experience mechanical property changes within the temperature range experienced in service. The test may be applied to other filters if thought applicable by agreement between the filter manufacturer and the purchaser.

ISO 4548-9:2007 specifies methods of measuring the effectiveness of either inlet or outlet anti-drain valves if fitted to a full-flow lubricating oil filter of the "spin-on" or "easy change" type, for internal combustion engines.

ISO 6415:2005 specifies the essential dimensions necessary for interchangeability of spin-on filters of the full-flow type for the filtration of lubricating oil for internal combustion engines. It also gives the designation and marking of these filters.

Specifies the essential dimensional characteristics necessary for the interchangeability of filter elements. Most filter elements are specified with two alternative internal diameters; however, the values listed in the "preferred" column of the table are recommended for future equipment.

ISO 4548-5:2013 specifies a method of testing the ability of full-flow lubricating oil filters for internal combustion engines to withstand an internal pressure surge such as occurs when an engine is started from cold, and cyclic internal pressure variations experienced during operation. These tests are intended for application to spin-on type filters and detachable filters with disposable elements with a maximum flow rate of 100 l/min.

ISO 4548-6:2012 specifies a method of testing full-flow lubricating oil filters for internal combustion engines to determine their ability to withstand a static pressure objective and to determine their burst pressure and the failure mode concerned. It does not apply to filters for use in aeronautical applications or plastic components.

ISO/TS 23556:2007 specifies a multipass soot-filtration test method using batch thermal gravimetric analysis (TGA), continuous online Fourier Transformation Infrared (FTIR), or other approved soot-measuring techniques for evaluating the initial filtration efficiency of single-stage, multiple-stage, centrifugal and other soot-removal devices (SRD) for internal combustion engines submitted to a constant flow rate of test liquid. The test procedure determines time-weighted average initial soot-removal efficiency for soot-removal devices. This test method is intended for application to SRD having a rated flow between 0,5 l/min and 75 l/min.

Specifies methods of measuring the effectiveness of either inlet or outlet anti-drain valves if fitted to a full-flow lubricating oil filter of the "spin-on" or "easy change" type, for internal combustion engines.

Specifies a method of testing the ability of oil filters to withstand an internal pressure surge such as occurs when an engine is started from cold, and cyclic internal pressure variations experienced during operation.

Specifies a method of testing the constructional integrity of oil filters to withstand engine or installation vibration. This test is intended to filters with disposable elements with a maximum flow rate of 100 l/min.

Establishes standard test procedures for measuring the performance of filters. It does not apply to filters for use in aeronautical applications. Includes the report of test results. Describes test rig and test liquid.
