摘要： This document specifies a test method for the quantitative determination of ignition delay of middle distillatefuels intended for use in compression ignition engines. The method utilizes a constant volume combustionchamber designed for operation by compression ignition, and employing direct injection of fuel intocompressed air that is controlled to a specified pressure and temperature. An equation is given to calculatethe derived cetane number (DCN) from the ignition delay *** standard is applicable to diesel fuels, including those containing FAME. The method is also applicable tomiddle distillate fuels of non-petroleum origin. However, users applying this standard especially tounconventional diesel fuels are warned that the relationship between derived cetane number and combustionbehaviour in real engines is not yet fully understood. The standard covers the ignition delay range from 3,3 msto 6,4 ms (61 DCN to 34 DCN). The combustion analyser can measure shorter or longer ignition delays, butprecision can be *** For the purpose of this European Standard, the expression “% (V/V)” is used to represent the volume fractionand “% (m/m)” the mass *** — The use of this standard may involve hazardous materials, operations and *** standard does not purport to address all of the safety problems associated with its use.

摘要： This International Standard describes a test method for assessing the resistance of paint coatings to separation from substrates when a right-angle lattice pattern is cut into the coating, penetrating through to the substrate. The property measured by this empirical test procedure depends, among other factors, on the adhesion of the coating to either the preceding coat or the substrate. This procedure is not to be regarded, however, as a means of measuring adhesion. Where a measurement of adhesion is required, attention is drawn to the method described in ISO 4624. NOTE 1 Although the test is primarily intended for use in the laboratory, the test is also suitable for field testing. The method described may be used either as a pass/fail test or, where circumstances are appropriate, as a six-step classification test. When applied to a multi-coat system, assessment of the resistance to separation of individual layers of the coating from each other may be made. The test can be carried out on finished objects and/or on specially prepared test specimens. Although the method is applicable to paint on hard (e.g. metal) and soft (e.g. wood and plaster) substrates, these different substrates need a different test procedure (see Clause 6). The method is not suitable for coatings of total thickness greater than 250 μm or for textured coatings. NOTE 2 The method, when applied to coatings designed to give a rough patterned surface, will give results which will show too much variation (see also ISO 16276-2).

摘要： This part of ISO 16232 describes a method for determining the nature of contaminant particles by identifying their elemental chemical composition using energy dispersive X-ray spectroscopy (EDX) in combination with a scanning electron microscope (SEM). The contaminant particles are extracted from automotive parts or components and deposited on the surface of a membrane filter. In addition to the number and size of particles as described in ISO 16232-7, this measurement gives the elemental composition of the particles analysed. This information can be used to classify the particles into likely material groups 1). This method cannot determine the nature of organic material 2). The analyses can either be carried out manually or fully automatically, provided the appropriate equipment is available.

摘要： The purpose of this part of ISO 16232 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, this part of ISO 16232 deals with particulate cleanliness only. It does not, therefore, cover appearance defects or contamination by liquid or gaseous materials. It covers the amount of residual particulate contaminants resulting from manufacturing processes and from the environment.

摘要： This part of ISO 16232 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 otherwise specified, this part of ISO 16232 deals with particulate contamination only. It does not, therefore, cover appearance defects or contamination by liquid or gaseous materials. It covers the amount and the nature of residual particles resulting from manufacturing processes and from the environment.

摘要： This part of ISO 16232 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, this part of ISO 16232 deals with particulate contamination only. It does not, therefore, cover appearance defects or contamination by liquid or gaseous materials. It covers the amount and the nature of residual particles resulting from manufacturing processes and from the environment.
