when can the new ball be taken in test cricket
Test cricket After 80 overs, the captain of the bowling side may take a new ball, although this is not required.[31]The captain will usually take the new ball: being harder and smoother than an old ball, a new ball generally favours faster bowlers who can make it bounce more variably. The roughened, softer surface of an old ball can be more conducive to spin bowlers, or those using reverse swing. The captain may delay the decision to take the new ball if he wishes to continue with his spinners (because the pitch favours spin). After a new ball has been taken, should an innings last a further 80 overs, then the captain will have the option to take another new ball.
Cricket ball In test cricket, a new ball is used at the start of each innings in a match. In Limited Over Internationals, two new balls, one from each end, are used at the start of each innings in a match. A cricket ball may not be replaced except under specific conditions described in the Laws of Cricket:
