This European Standard
22、shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2013, and conflicting national standards shall be withdrawn at the latest by November 2013. Attention is drawn to the possibility that some of the elements of thi
23、s document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13383-2:2002. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trad
24、e Association. In comparison with the previous version, the following changes have been made. changes and clarifications to the sampling and sample reduction clauses, including a new informative annex on sampling from waterborne plant; introduction of requirements for sample preparation for the Micr
25、o-Deval test previously in EN 13383-1; deletion of an unused wet sieving method for the determination of particle size distribution of coarse gradings of armourstone. removal to an informative annex of a previously normative alternative to the reference method for determination of mass distribution
26、of light and heavy gradings. Otherwise the majority of the changes from the previous version are editorial. EN 13383 Armourstone consists of the following parts: Part 1: Specifications Part 2: Test methods According to the CEN/CENELEC Internal Regulations, the national standards organisations of the

29、-2:2013EN 13383-2:2013 (E) 5 1 Scope This European Standard specifies sampling and test methods for natural, artificial and recycled aggregates for use as armourstone. This European Standard specifies the reference methods to be used for type testing and in case of dispute where an alternative metho
30、d has been used. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the test method has been established. 2 Normative references The following documents, in whole or in part, are normatively referenced in thi
31、s document and are indispensable for its application. For dated references, only the edition cited applies.

Test laboratories can determine the time required to achieve constant mass for specific types and sizes of sample dependent upon the
46、 drying capacity of the oven used. 4 Methods for sampling 4.1 General This clause describes methods for obtaining samples of armourstone from preparation and processing plants including stocks and from silos, stockpiles and deliveries. NOTE It is preferable that armourstone should be sampled at the
47、quarry or during the loading for transport (or unloading). The aim of sampling is to obtain samples that are representative of the average properties of the batch. The methods described are also suitable for obtaining sampling increments which are to be tested separately. Methods to be used for samp
48、le reduction are also given. 4.2 Principles of sampling Proper and careful sampling and sample transport is a prerequisite for an analysis that will give reliable results. The correct use of the specified apparatus and methods helps to avoid biased sampling inclusive the possibility of human bias in
49、troduced by visual selection. Sampling variation caused by the heterogeneity of the batch shall be reduced to an acceptable level by taking an adequate number of sampling increments. NOTE For guidance on numbers and sizes of samples and test portions for testing armourstone as specified in EN 13383-1:2013, see Annex
