Dimensions and External Defects of Refractories - Test Method - BS 1902-3.19:1996, ISO 12678-1:1996
Methods of testing refractory materials. General and textural properties. Measurement of dimensions and external defects of refractory bricks. Dimensions and conformity to drawings.
This standard provides simple methods for routine measurement of corner and edge defects, as well as other surface imperfections of refractory bricks. It does not apply to the measurement of internal defects.
Also specified are simple methods for routine measurement of dimensions of refractory bricks and methods for inspection of conformity to shape, determining concavity, convexity and out-of-squareness.
Criteria for acceptance or rejection of bricks are not established in this standard.
