@Shubham.

Class A bricks have a compressive strength 125N/mm^2 and water absorption less than 4.5%.

Class B bricks have a compressive strength 75N/mm^2 and water absorption less than 7%.

@ Ravi: Crushing strength is 5.5Mp0a & Compressive strength is 3.5Mpa for good bricks (generally).

@Shubhm: another name of 1st class brick is A-Class brick.

@All:
Crushing strength minimum
Second class brick; 7.5Mpa.
First class brick: 10.5 MPa.

1st class brick10.5 N/mm2.

Could you tell what is the strength of A-class brick? This is an NBCC question.
