EN 1402-1:2003 (E) 3 Foreword This document (EN 1402-1:2003) has been prepared by Technical Committee CEN/TC 187 “Refractory products and materials“, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2004, and conflicting national standards shall be withdrawn at the latest by April 2004. This document supersedes ENV 1402-1:1994. EN 1402 “Unshaped refractory products“ consists of eight parts: Part 1: Introduction and classification Part 2: Sampling for testing Part 3: Characterization as received Part 4: Determination of consistency of castables Part 5: Preparation and treatment of test pieces Part 6: Measurement of physical properties Part 7: Tests on pre-formed shapes Part 8: Determination of complementary properties According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

EN 1402-1:2003 (E) 4 Introduction The general objective of this part of EN 1402 is to define, with as much accuracy as possible, the control of unshaped refractory products with special reference to: a) quality control; b) checking the conformity of the delivery as compared with claimed properties; c) the control of batch homogeneity; d) the final control of linings. Properties are unavoidably influenced by industrial placing as a result of the equipment, environmental conditions and often by specific site conditions (target date, location). Quality control and final control of lining should not be considered in the same documents, since the former requires accuracy and clean operative methods while the latter requires the control of the placing. Unshaped refractory products used in industrial linings are not fired, so that firing which results from use creates complicated conditions that make control difficult. The main points to be mentioned are: i) the temperature gradient, the consequence of which is a property gradient; ii) the level of maximum temperature reached on the hot face directly depends on the working temperature of the equipment; iii) the life of the equipment may be numbered in hours or in years. It should be noted that properties measured in the laboratory frequently do not reflect the properties of the material when installed.

EN 1402-1:2003 (E) 5 1 Scope This part of this European Standard defines terms relating to unshaped refractory products and establishes the classification for the various types of products. Raw materials and crushed or granulated refractory materials which do not contain any binder are excluded. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places 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 referred to applies (including amendments). EN 1094-4, Insulating refractory products - Part 4: Determination of bulk density and true porosity. EN 1402-6, Unshaped refractory products - Part 6: Measurement of physical properties. ISO 565, Test sieves - Metal wire cloth, perforated metal plate and electroformed sheet - Nominal sizes of openings. 3 3Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 unshaped refractory materials mixtures which consist of an aggregate and a bond or bonds, prepared ready for use either directly in the condition in which they are supplied or after the addition of one or more suitable liquids NOTE 1They can contain metallic, organic or ceramic fibre material. NOTE 2These mixtures are either dense or insulating. Insulating mixtures are those whose true porosity is not less than 45 % when determined in accordance with EN 1094-4, using a test piece fired to specified conditions. 3.2 pre-formed shapes shapes made from unshaped refractory materials, cast or moulded and pre-treated by the manufacturer, so that they can be directly placed in service NOTEThey may have a thermal pre-treatment. 4 Product types and methods of placement 4.1 Refractory castables 4.1.1 General Mixtures of refractory aggregates and bond(s), mainly supplied dry and used after the addition and mixing with water or another liquid. They are placed by casting with vibration, by casting without vibration (self-flowing), by rodding, by shotcreting or when necessary by tamping. The bond is formed and hardening takes place without heating.

EN 1402-1:2003 (E) 6 4.1.2 Regular castable Hydraulically bonded refractory castable containing cement but without deflocculant. 4.1.3 Deflocculated castable Hydraulically bonded refractory castable containing cement, a minimum of 2 % by weight of ultra fine particles (less than one micron) and at least one deflocculating agent. This type is in turn sub-divided into the four categories given in Table 1. Table 1 Categories of deflocculated cement castable Content (%) CaO Category MinMax Medium cement castable (MCC) 2,5- Low cement castable (LCC) 1,0? 2,5 Ultra low cement castable (ULCC) 0,2? 1,0 No cement castable (NCC)0? 0,2 4.1.4Chemically bonded castable Refractory castable containing one or more chemical bonds (see 3.3) which cause hardening. 4.2 Refractory gunning materials Mixtures of refractory aggregates and bond(s), specially prepared for placing by pneumatic or mechanical projection. They may be either: a) castables (see 4.1) (dense or insulating) which are supplied dry and used after the addition of water during or before gunning; b) plastics (see 4.3.2) which are especially designed for gunning under high air pressure with special equipment, and are normally delivered in a ready to use state. According to the type of bond, a further distinction is made between hydraulically bonded, chemically bonded and ceramic bonded gunning materials. 4.3 Refractory ramming materials 4.3.1 Refractory ramming mixes Materials which are non-coherent before use, made up of refractory aggregates, bond(s) and if necessary liquid(s). According to the type of product, the main bond may be ceramic, chemical (inorganic or organic-inorganic) or organic. The materials are used as delivered or after the addition of liquid(s) and placed by ramming (manual or mechanical) or vibration. They harden under the action of heat above ambient temperature. 4.3.2 Plastic refractory materials Materials which are coherent and ready for use, with a plastic consistency, made up of refractory aggregates, bond(s) and liquid(s). According to the type of product, the main bond may be ceramic, chemical (inorganic or organic-inorganic) or organic.

They harden under the action of heat above ambient temperature. Plastic refractory materials have indices of workability (see EN 1402-3) of greater than 14 after stabilization. 4.4 Refractory jointing materials Materials intended for laying and jointing bricks or blocks by trowelling, grouting in the joints, or dipping the brick or block to be bonded. They are mixtures of f
