摘要： ISO 14596:2007 specifies a method for the determination of the sulfur content of liquid petroleum products, additives for petroleum products, and semi-solid and solid petroleum products that are either liquefied by moderate heating or soluble in organic solvents of negligible or accurately known sulfur content. The method is applicable to products or additives having sulfur contents in the range 0,001 % (m/m) to 2,50 % (m/m); higher contents can be determined by appropriate dilution. Other elements do not interfere at concentrations anticipated in the materials subject to this analysis.

摘要： This European Standard specifies the requirements for factory made products of expanded polystyrene whichare used for frost insulation of roads, railways, trafficked areas, light weight fill for reduction of horizontal andvertical earth pressure and other civil engineering applications.The products are manufactured in the form of boards or blocks. The standard also covers specially cut shapedboards or blocks.The standard describes product characteristics and includes procedures for testing, evaluation of conformity,marking and labelling.The standard does not specify the required class or level of a given property to be achieved by a product todemonstrate fitness for purpose in a particular application. The classes and levels required for a givenapplication are to be found in regulations or non-conflicting standards.For applications where thermal resistance is required, products with a declared thermal resistance lower than0,25 m2?K/W or a declared thermal conductivity greater than 0,060 W/(m?K) are not covered by this standard.This standard does not cover in situ insulation products and products intended to be used for the insulation ofbuildings, of building equipment and industrial installations or products intended for acoustic insulation.

摘要： This European Standard specifies a method for the determination of absolute vapour pressure of liquidpetroleum products at elevated temperatures.The conditions used in the test described in this standard are a vapour to liquid ratio of 3:2 and an initialinjection temperature of 37,8 °C or 30,0 °C.The method described is suitable for testing air-saturated samples that exert an air-saturated vapour pressureof between 9 kPa and 500 kPa at temperatures between 40 °C and 100 °C.This European Standard is applicable to fuels containing oxygenated compounds up to the limits stated in therelevant EC Directive 85/536/EEC [3].NOTE 1 If a sample injection is into a test chamber which is raised to 37,8 °C and the vapour to liquid ratio is 4:1, theinitial measurement corresponds with the measurement in Part 1 of this standard.NOTE 2 For the purposes of this European Standard, the term “% (V/V)” is used to represent the volume fraction.WARNING — Use of this standard may involve hazardous materials, operations and equipment. Thisstandard does not purport to address all of the safety problems associated with its use. It is theresponsibility of the user of this standard to establish appropriate safety and health practices and todetermine the applicability of regulatory limitations prior to use.

摘要： This European Standard specifies the following requirements:a) requirements for measurement sections and sites with respect to performing emission measurements;b) requirements for the measurement objective, plan and report of emission measurements of air pollutantsand reference quantities to be carried out in waste gas ducts at industrial plants.This European Standard applies to periodic measurements using manual or automated reference methods(RM).This European Standard specifies generic principles which can be applied to perform emission measurementsat different plant types and to meet different measurement objectives.NOTE The measurement objective is specified by the customer. The testing institute identifies the measurementobjective and related regulatory requirements at the beginning of the measurement planning. Where measurements arebeing made for regulatory purposes, the customer should seek approval from the competent authority.This European Standard specifies procedures for taking representative samples in waste gas ducts.This European Standard specifies a procedure for finding the best available sampling point for automatedmeasuring systems used for continuous monitoring of emissions.The planning and reporting aspects of this European Standard are applicable to emission measurements atdiffusive and fugitive emission sources.This European Standard does not address aspects of structural safety of chimneys and ducts, construction ofworking platforms and safety of personnel using them.
