BS 1902-5.3 is a British Standard for the glass and ceramics Industry. BS 1902-5.11 is a part of a series on refractory and thermal properties.
BS 1902-5.3 provides specifications relating to methods of testing refractory materials.
Two laboratory methods have been included in BS 1902-5.3.
BS 1902-5.3 describes a method for determining the thermal expansion of refractory materials. It is applicable only to products which have been fired to a temperature equal to or greater than the upper limit of intended testing. The maximum temperature for testing is 1100°C.
BS 1902-5.3 includes Scope, Designation, Definition, Principle, Apparatus, Test Pieces, Calibration, Procedure, Calculation and Test Report. It also includes relevant tables and figures.
Note 1: This standard 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 temperature is restricted because of the material recommended for the equipment and the absence of water cooling.
BS 1902-5.3 on testing refractory materials is useful for:
Determining the thermal expansion is vital for the glass and ceramics industry because refractory materials must be resistant to thermal shock. They must also be physically and chemically stable at very high temperatures.
They are also used in buildings and system components, so standardization becomes crucial for refractory materials especially when it comes to thermal expansion. Efficient refractory materials are resilient to thermal stress and physical events generated by heat.
BS 1902-5.3 shall benefit the users to test the thermal expansion of refractory materials effectively. These materials are used in various industries and it is extremely important to ensure that the standard and quality are maintained and that the thermal expansion of refractory materials is ideal. This can ensure safety and maximum credibility.
BS 1902-5.3:1986 supersedes BS 1902-1A:1966 Section 10. BS 1902-5.3:1986 includes some technical changes with respect to BS 1902-1A:1966 Section 10 which will be deleted by amendment.
