ASTM C410-60(1997)

1.1 This specification covers brick made from clay or shale or mixtures thereof and are suitable for surfacing industrial floors. Ceramic shapes known as quarry tile are not covered by this specification. Four types of industrial floor brick are covered (Note):

1.1.1 Type T -For use where a high degree of resistance to thermal and mechanical shock is required but low absorption is not required.

1.1.2 Type H -For use where resistance to chemicals and thermal shock are service factors but low absorption is not required.

1.1.3 Type M -For use where low absorption is required. Brick of this type are normally characterized by limited mechanical (impact) shock resistance but are often highly resistant to abrasion.

1.1.4 Type L -For use where minimal absorption and a high degree of chemical resistance are required. Brick of this type are normally characterized by very limited thermal and limited mechanical (impact) shock resistance but are highly resistant to abrasion.
