8、 Methods of test for dense shaped refractory products Part 13: Specification for pyrometric reference cones for laboratory use, published by the European Committee for Standardization (CEN). EN 993-13 was produced as a result of international discussions in which the UKtook an active part. A British
9、 Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front c

26、BSI 12-1999 3 1 Scope This Part of EN993 specifies the characteristics of a standard series of pyrometric reference cones, which are used for determining the pyrometric cone equivalent (refractoriness) of refractory materials, over the temperature range1500 C to1800 C. The pyrometric reference cones
27、 specified are suitable for use in the procedure described in EN993-12, excluding determination of1500 C and1800 C. 2 Normative reference This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate pla
28、ces in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication refe
29、rred to applies. EN 993-12, Methods of test for dense shaped refractory products Part 12: Determination of pyrometric cone equivalent (refractoriness). 3 Definitions For the purposes of this Part of EN993, the following definitions apply. 3.1 pyrometric reference cone a blunt-tipped skew triangular
30、pyramid with sharp edges, of specified shape and dimensions and of such composition that, when mounted and heated under specified conditions, it bends in a known manner with reference to the temperature (see3.2) 3.2 reference temperature; temperature of collapse the temperature at which the tip of a
31、 pyrometric reference cone reaches the level on which the base of the cone is mounted when the cone is heated at a specified rate under specified conditions 4 Dimensions and shape of cones 4.1 The nominal dimensions of a cone shall be as shown inFigure 1. 4.2 The shape of a cone shall be as indicate
32、d inFigure 2. 4.3 The cone shall lean in the direction of an edge, as inFigure 2. The angle to the vertical to be made by the leading edge or face when the cone is mounted, shall be8 1 . 5 Reference temperatures Each reference cone shall be of such composition that the temperature of collapse is one
33、 of the temperatures shown inTable 1, with a tolerance of 5K.

34、g to this European Standard shall be suitable for heating to its reference temperature at a rate of2,5 C/min. 7 Verification of temperature of collapse The reference temperature of each batch of cones having the same nominal reference temperature shall be verified for conformity to clause5 by carryi
35、ng out the procedure specified in EN993-12 on a sample of the batch. The temperature of collapse shall be determined by a calibrated thermocouple. The sample, to be taken at random from the batch, shall consist of2% of the batch with a minimum of two cones. 8 Marking Each reference cone conforming t
36、o this European Standard shall be marked with the appropriate cone designation as shown inTable 1.
