Ashraf told reporters that accepting ICC's recommendation would be a step towards improving the game and BCCI should also review its policy on using the DRS.
"I feel accepting the DRS system will be in the larger interest of the sport," he said.
International Cricket Council (ICC) recommended the mandatory use of Decision Review System in all Tests though it was not completely error free.
Since the decisions taken under DRS has helped the umpires, players and the game, Zaka Ashraf insists on the use of the Decision Review System.
"It is a system which is also beneficial for the umpires in the long run," Ashraf said.
Unlike BCCI, PCB has supported DRS as it will definitely help the game of cricket, and are presently trying to get the sponsorship for using it in their upcoming ODI series against Australia to be played next month.
PCB chairman also said that the board was waiting for July 12th as Dhaka High Court's injunction against Pakistan would end so that Bangladesh could still tour the country.
"We are in constant touch with the Bangladesh board so let us see what happens after July 12th," he said.
It is learnt that Bangladesh had to pull out of the tour of Pakistan because of the order issued by the High Court in April.
