Methods of test for dense shaped refractory products - Part 13: Specification for pyrometric reference cones for laboratory use

This part of EN 993    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 range 1500 to 1800°C.  The pyrometric reference cones specified are  suitable for use in the procedure described in EN 993-12, excluding determination of 1500 and 1800°C.

Prüfverfahren für dichte geformte feuerfeste Erzeugnisse - Teil 13: Festlegungen für Referenz-Brennkegel für den Laboratoriumsgebrauch

Dieser Teil von EN 993  legt die Werte einer Standardreihe von Referenz- Brennkegeln für den Temperaturbereich von 1500°C bis 1800°C fest, die zur Bestimmung des Kegelfallpunktes (Feuerfestigkeit) von feuerfesten Werkstoffen benutzt werden. Die in dieser Europäischen Norm beschriebenen Referenz-Brennkegel sind geeignet für den Einsatz im Verfahren nach EN 993-12, mit Ausnahme der Bestimmung bei 1500°C und 1800°C.

Overview

EN 993-13:1995 (CEN) specifies the required characteristics of a standard series of pyrometric reference cones for laboratory use. These reference cones are used to determine the pyrometric cone equivalent (PCE) - a measure of the refractoriness - of dense shaped refractory products. The standard covers cones intended for testing in the temperature range 1500 to 1800 °C and is intended to be used in conjunction with the test procedure described in EN 993-12, excluding the specific determination at the end-point temperatures 1500 °C and 1800 °C.

Key topics and requirements

• Scope and purpose: Defines the characteristics required for laboratory pyrometric reference cones used to assess refractoriness of dense shaped refractories.
• Temperature range: Cones specified are applicable over 1500–1800 °C for determining pyrometric cone equivalent.
• Compatibility: Designed for use with the test procedure in EN 993-12, except for determinations at exactly 1500 °C and 1800 °C.
• Standardization: Part of the EN 993 series for methods of test for dense shaped refractory products; published under CEN and referenced in national standards (e.g., SIST EN 993-13).
• Classification context: Falls under ICS 81.080 (Refractories), providing consistency in refractoriness measurement across laboratories.

Note: EN 993-13 sets characteristics of reference cones (shape, markings, material specification aspects) but does not replace the procedural details contained in EN 993-12.

Applications

EN 993-13 is directly relevant where accurate and comparable refractoriness measurements are required:

• Quality control and acceptance testing in refractory production.
• Laboratory determination of pyrometric cone equivalent (PCE) for research and development.
• Performance verification in industries that use refractories, such as steelmaking, glass, cement, non-ferrous metallurgy and ceramics.
• Standardization and calibration activities in testing laboratories and conformity assessment bodies.

Who should use this standard

• Materials scientists and laboratory technicians performing refractoriness tests.
• Quality control and R&D engineers in refractory manufacturing.
• Test laboratories seeking traceable, standardized reference cones.
• Standards committees and procurement specialists specifying test equipment and reference materials.

Related standards

• EN 993-12 - test procedure for determining pyrometric cone equivalent (use EN 993-13 cones with EN 993-12, excluding 1500 and 1800 °C determinations).
• Other parts of the EN 993 series covering methods of test for dense shaped refractory products.
