BS 1902-5.11 is a British Standard for the glass and ceramics industry. BS 1902-5.11 is the 5th part of refractory and thermal properties, which specifies the method of determination of thermal spalling resistance by the prism test.
The thermal spalling resistance of refractory products as outlined in BS 1902-5.11 cannot be readily quantified. Results have to be expressed in terms of the relative performance of a number of refractory products when tested by the same method.
Two Laboratory Methods have been selected to be included in BS 1902-5.11. BS 1902-5.11 contains the prism test method and was prepared under the direction of the Refractory Products Standards Committee.
BS 1902-5.11 includes the Designation, Definition, Principle, Apparatus, Test Pieces, Procedure and Test Report.
Note 1: BS 1902-5.11 is to be read in conjunction with BS1902: Section 5.0 ‘Introduction’ and BS 1902: Section 3.1 ‘Guidance on sampling’. Section 5.0 sets out the general arrangement of BS 1902 and lists the Sections of Part 5.
Note 2: The titles of the publications referred to in this standard are listed inside the back cover.
BS 1902-5.11 on Refractory Materials for Ceramics is useful for:
Determining the thermal spalling resistance is crucial for the Glass and Ceramics Industry because various materials used in several industries require refractory materials. These industries need high quality refractory materials to endure high temperatures and physical wear and corrosion by chemical agents. Efficient Refractory materials are resilient to thermal stress and physical events generated by heat.
BS 1902-5.11 guidelines mention the methods to ensure ideal testing of refractory materials.
BS 1902-5.11 helps in the testing and determining thermal spalling resistance by the prism test. BS 1902-5.11 shall benefit the users by allowing them to test the thermal spalling resistance of refractory materials effectively.
These materials are used in various industries and it is extremely important to ensure that the BS 1902-5.11 best practice guidance is followed. This can assure high durability of products using best industry practices for manufacture.
BS 1902-5.11:1986 supersedes BS 1902-1.1:1966. BS 1902-5.11:1986 includes some technical changes with respect to BS 1902-1A:1966 which will be deleted by amendment. These include:
