This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. A similar standard has been developed fo

According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, For

25、:2018 (E) 4 Introduction Following an extended evaluation of available methods for content analysis in construction products (CEN/TR 16045) it was concluded that multi matrix and multi-element digestion methods have preference over methods developed for single matrices or small groups of matrices. T

26、his implies that for inorganic substances aqua regia digestion is preferred for the digestion of construction products for content analysis. This document has been adopted from the work carried out in the context of CEN/TC 292 and CEN/TC 400 and is very similar to EN 13657 Characterization of waste

27、Digestion for subsequent determination of aqua regia soluble portion of elements 1 and EN 16174 Sludge, treated biowaste and soil Digestion of aqua regia soluble fractions of elements 2. This Technical Specification is part of a modular horizontal approach which was adopted in CEN/TC 351. Horizontal

28、 means that the methods can be used for a wide range of materials and products with certain properties. Modular means that a test standard developed in this approach concerns a specific step in assessing a property and not the whole chain of measurement (from sampling to analyses). Beneficial featur

29、es of this approach are that modules can be replaced by better ones without jeopardizing the standard chain and duplication of work of in different Technical Committees for Products can be avoided as far as possible. The modules that relate to the standards developed in CEN/TC 351 are specified in C

30、EN/TR 16220 3, which distinguishes between the modules. This Technical Specification belongs to the analytical step. The use of modular horizontal standards implies the drawing of test schemes as well. Before executing a test on a certain construction product to determine certain characteristics it

31、is necessary to draw up a protocol in which the adequate modules are selected and together form the basis for the entire test procedure. WARNING Persons using this Technical Specification should be familiar with usual laboratory practice. The reagents used in this Technical Specification are strongl

32、y corrosive and partly very toxic. Safety precautions are absolutely necessary, not only due to the strong corrosive reagents, but also to high temperature and high pressure. The use of laboratory-grade microwave equipment with isolated and corrosion resistant safety devices is required. Domestic (k

33、itchen) type microwave ovens should not be used, as corrosion by acid vapours may compromise the function of the safety devices and prevent the microwave magnetron from shutting off when the door is open, which could result in operator exposure to microwave energy. All procedures should be performed

34、 in a fume hood or in closed force-ventilated equipment. By the use of strong oxidising reagents, the formation of explosive organic intermediates is possible, especially when dealing with samples with a high organic content. Do not open pressurized vessels before they have cooled down. Avoid contac

35、t with the chemicals and the gaseous reaction products. IMPORTANT It is absolutely essential that tests conducted according to this Technical Specification be carried out by suitably trained staff.

40、 and zirconium (Zr). Solutions produced by the methods are suitable for analysis by cold vapour atomic absorption or fluorescent spectrometry (CV-AAS, CV-AFS), for mercury (Hg). The method in this Technical Specification is applicable to construction products. Digestion with aqua regia will not nece

41、ssarily accomplish total decomposition of the sample. The extracted analyte concentrations may not necessarily reflect the total content in the sample. NOTE Construction products include e.g. mineral-based products (S); bituminous products (B); metals (M); wood-based products (W); plastics and rubbe
