标准号: DIN EN ISO 15103-2-2007

摘要： This part of ISO 15103 specifies the methods of preparation of test specimens and the test methods to beused in determining the properties of poly(phenylene ether) moulding and extrusion materials. Requirementsfor handling test material and for conditioning both the test material before moulding and the specimensbefore testing are given here.Procedures and conditions are described for the preparation of test specimens, and procedures for measuringproperties of the materials from which these specimens are made are given. Properties and test methodswhich are suitable and necessary to characterize poly(phenylene ether) moulding and extrusion materials arelisted.The properties have been selected from the general test methods in ISO 10350-1:1998. Other test methods inwide use for, or of particular significance to, these moulding and extrusion materials are also included in thispart of ISO 15103, as are the designatory properties specified in ISO 15103-1.In order to obtain reproducible and comparable test results, it is necessary to use the methods of specimenpreparation and conditioning, the specimen dimensions and the test procedures specified herein. Valuesdetermined will not necessarily be identical to those obtained using specimens of different dimensions orprepared using different procedures.

标准号: BS EN ISO 11890-2-2006

摘要： ISO 11890-2:2006 is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products.It specifies a method for the determination of the volatile organic compound (VOC) content of paints, varnishes and their raw materials. ISO 11890-2 is preferred if the expected VOC content is greater than 0,1 % by mass and less than about 15 % by mass. When the VOC content is greater than about 15 % by mass, the less complicated method given in ISO 11890-1 may be used.This method assumes that the volatile matter is either water or organic. However, other volatile inorganic compounds can be present and might need to be quantified by another suitable method and allowed for in the calculations.

摘要： ISO 16000-7:2007 specifies procedures to be used in planning of air measurements to determine the concentrations of asbestos in indoor atmospheres. Careful planning of the measurement strategy is important, because the results can become the basis of recommendations for major building renovations, or for the return of a building to normal occupancy status after removal of asbestos-containing materials.ISO 16000-7:2007 uses the following definition for indoor environments as specified in ISO 16000-1: dwellings having living rooms, bedrooms, do-it-yourself (DIY) rooms, recreation rooms, cellars, kitchens and bathrooms; workrooms or workplaces in buildings which are not subject to health and safety inspections in regard to air pollutants (for example, offices and sales premises); public and commercial buildings (for example, hospitals, schools, kindergartens, sports halls, libraries, restaurants and bars, theatres and other function rooms); cabins of vehicles and public transport.

摘要： This International Standard specifies an empirical method for assessing the resistance of a coating of paint, varnish or related product to cracking and/or detachment from a metal sustrate when subjected to gradual deformation by indentation under standard conditions (see 7.1). For a multi-coat system, each coat may be tested sparately or the complete system may be tested. The method may be carried out as follows: either as a "pass/fail" test, by testing to a specified depth of indentation to assess compliance with a particular requirement; or by gradually increasing the depth of indentation to determine the minimum depth at which the coating cracks and/or becomes detached from the substrate.

标准号: BS ISO 2469-2007

摘要： This International Standard describes the general procedure for measuring the diffuse radiance factor of all types of pulp, paper and board. More particularly, it specifies in detail in Annex A the characteristics of the equipment to be used for such measurements, and in Annex B the procedures to be used for calibrating that equipment. This International Standard may be used to measure the radiance factors and related properties of materials containing fluorescent whitening agents, provided that the UV radiation content in the illumination has been adjusted to the level specified in the specific International Standard describing the measurement of the property in question. This International Standard describes in Annex C the preparation of fluorescent reference standards, although the procedures for using these standards are not included, since their use is described in detail in the specific International Standards describing the measurement of the properties of materials containing fluorescent whitening agents.

标准号: BS ISO 22891-2007

摘要： ISO 22891:2007 specifies a method for the calculation of transmittance based upon diffuse reflectance measurements.The use of the method is restricted to white and near-white translucent papers. If it is necessary to determine the transmittance of papers which contain fluorescent whitening agents, the fluorescence emission is eliminated using the prescribed UV cut-off filter.
