The work of preparing Internation
9、al Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO,
10、 also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part
11、1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesAttention is drawn to the possibility that some of the elements

14、)Monolithic refractory products Determination of resistance to explosive spalling1 ScopeThis International Standard specifies a method for determining the resistance to explosive spalling of monolithic refractories.2 Normative referencesThe following documents, in whole or in part, are normatively r
15、eferenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 836, Terminology for refractoriesISO 1927-5, Monolithic (unshaped)
16、refractory products Part 5: Preparation and treatment of test pieces3 Terms and definitionsFor the purposes of this document, the terms and definitions given in ISO 836 and the following apply.3.1transition-point temperatureindication of the dewaterability of the castableNote 1 to entry: A low trans
17、ition-point temperature indicates high dewaterability and this directly relates to high explosion resistance. A castable having a high transition-point temperature indicates poor dewaterability and low explosion resistance. (See Annex A for further information.)4 PrincipleA test specimen is prepared
18、 by casting and allowed to cure. The specimen is then enclosed in an explosion-proof cage before being placed in a preheated kiln at a prescribed temperature.NOTE The method has been developed as a practical way of measuring a property. It is not designed to form part of acceptance testing for monol
19、ithic products. Rather, it is more useful for comparative purposes. It is also useful for monolithic design purposes5 Apparatus5.1 Mould. A split cylindrical mould with internal dimensions of 80 mm height and 80 mm diameter and having a provision to allow for in situ casting of a thermocouple into t
20、he centre of the cast specimen.5.2 Thermocouple. A thin wire thermocouple (preferably Type K). The thermocouple needs to be sufficiently insulated to withstand heating to test temperature inside and long enough to reach a temperature recorder located sufficient distance from the kiln to avoid damage
21、.5.3 Temperature recorder. Any instrument capable of recording the temperature of the thermocouple, either continuously or at short intervals to an accuracy of 1 C. ISO 2013 All rights reserved 1BS ISO 16334:2013ISO 16334:2013(E)5.4 Explosion-proof cage. A cube with approximate dimensions of 150 mm
22、per side, constructed of stainless steel mesh, having at least 60 % openings, and one side able to be opened. The construction should be strong enough to withstand explosion of the test specimen at the test temperature.5.5 Kiln. Electric or gas, capable of restoring the kiln temperature to the requi
23、red test temperature to within 5 C, within 5 min after the test specimen is placed in the kiln.5.6 Timing device. Any convenient timing device accurate to 1 s.6 Test specimensThe test specimen shall be prepared in accordance with ISO 1927-5, using the mould as described in 5.1. If information about
24、transition-point temperature is required, a wire thermocouple shall be cast in situ into the centre of the test specimen. The test specimen dimensions shall be 80 mm diameter by 80 mm height, with each dimension accurate to 1 mm. Following casting, the test specimen shall be prevented from drying pr
