ISO 16232-1:2007 defines the vocabulary used in the characterization and measurement of particulate contamination of parts, components, sub-assemblies and assemblies constituting the fluid circuits of internal combustion engines of road vehicles. This applies to all components that may come into contact with a liquid (e.g. oil, fuel, air conditioning refrigerant, coolant), a solid lubricant or a…

ISO 16232-2:2007 describes the principles of extraction of contaminants from a component by the agitation method. It is preferably applied to components that are hollow and are suited to being agitated by an operator or by an appropriate mechanical device. This agitation method can be employed on its own or in association with other methods of extraction described in the ISO 16232 series. Unless…

ISO 16232-3:2007 describes the principles of extraction of contaminants from a component by pressure rinsing. It is preferably applied to components of which the surface to be examined is accessible by a jet of test liquid. This method can be employed on its own or in association with other methods of extraction described in the ISO 16232 series. Unless otherwise specified, ISO 16232-3:2007 deals…

ISO 16232-4:2007 describes the principles of extraction of contaminants from a component either by immersion in an ultrasonic bath or by applying ultrasonic vibrations directly via sonotrodes. It is preferably applied to small and medium sized components of various geometry of which both internal and/or external surfaces are examined (e.g. joint seals, gears, etc). It is also applicable to small…

ISO 16232-5:2007 describes the principles of extraction of contaminants by test on a laboratory functional test bench with the test liquid flowing under pressure or under vacuum. It is applicable to both active and passive components through which the fluid can easily flow. Unless otherwise specified, ISO 16232-5:2007 deals with particulate contamination only. It does not, therefore, cover…

The purpose of ISO 16232-6:2007 is to determine the mass of particulate contamination by gravimetric analysis. Contaminants are separated from the extraction liquid by filtration. It applies to automotive components in contact with a fluid. Unless otherwise specified, ISO 16232-6:2007 deals with particulate cleanliness only. It does not, therefore, cover appearance defects or contamination by…

ISO 12357-2:2007 lays down test conditions and strength requirements to be met by: drawbar couplings and corresponding drawbar eyes for rigid drawbars which are provided for use on rigid drawbar trailers with a maximum design total mass exceeding 3,5 tonnes anda vertical static load exceeding 10 % of their design total mass, and/ora vertical static load greater than 1 000 kg and up to 2 000 kg;…

ISO 1726-2:2007 specifies dimensions to ensure interchangeability between a low coupling height tractor vehicle and a coupled high-volume semi-trailer, the two together constituting a high-volume articulated vehicle. It specifies certain interchangeability dimensions, including those of the optimised gooseneck contour, as well as operating dimensions related to angle values. The specifications…
