The changes to the playing conditions for different formats of cricket, which include amendments to Powerplays, DRS, no-balls and bouncers among others, will take effect from October 30, when Sri Lanka play New Zealand in a Twenty20 international in Pallekele.

These recommendations were made by the ICC's Cricket Committee in June, and they were endorsed by its Chief Executives Committee later that month.

General changes

DRS (Test and ODIs)
An amendment has been made to the LBW protocols. The margin of uncertainty applicable to the point of impact with the pad has been increased so that it is the same as provided for determining the projected point of impact with the stumps. For example, if the centre of the ball is shown to be impacting in line within an area demarcated by a line drawn down the middle of the outer stumps (and the bottom of the bails), then the decision will always be out.

If the whole of the ball is shown to be impacting outside the line of the stumps, then the decision will always be not out. If there is anything in between, the original on-field decision will stand.

No-balls (All formats)
After every dismissal that is not permitted off a no-ball, and subject to the availability of technology, the third umpire will check for a foot fault and advise the on-field umpire accordingly over a two-way radio.

Dead ball (All formats)
The playing conditions have been altered to include the use of the Spydercam, a camera that moves over the field on suspended cables, by broadcasters. If the ball, while in play, is hit by the batsman onto the camera or its cables, it will be called a dead ball.

Over-rates (All formats)
The allowances given to the fielding team because of time wasting by the batting team will be deducted from the allowances granted to the batting team in the determination of its over-rate.

Changes for Test matches

Day-night Tests
Participating countries can decide whether to play a day-night Test. The two boards will decide on the hours of play - six hours per day - and on the specifics of the ball that will be used.

Although the duration of the lunch and tea intervals remain unchanged - 40 and 20 minutes respectively - the host team, with the consent of the other side, can apply to the ICC for an approval for intervals of 30 minutes each.

Changes for ODIs

Powerplays and fielding restrictions
There will be only two blocks of Powerplay overs, instead of three. For uninterrupted innings, the first block will be during the first ten overs and only two fielders will be allowed outside the 30-yard circle. The second block, comprising five overs, will be taken by the batting side and must be completed by the 40th over. Only three fielders will be allowed outside the circle during the second Powerplay.

During non-Powerplay overs, a maximum of four fielders can be placed outside the circle, a reduction from the earlier five.

Short-pitched deliveries
Law 42.6 (a) has been amended to allow the bowler a maximum of two short-pitched deliveries per over in an ODI.

Changes for Twenty20 internationals

One-over per side eliminator
In both innings of the eliminator, the fielding side will choose which end to bowl from. Only nominated players in the main match may participate in the eliminator. Should any player be unable to continue to participate in the eliminator due to injury, illness or other wholly acceptable reasons, the relevant laws and playing conditions as they apply in the main match shall also apply in the eliminator. Any penance time being served in the main match shall be carried forward to the eliminator.

The fielding captain or his nominee shall select the ball with which he wishes to bowl his over in the eliminator from the box of spare balls provided by the umpires. The box will contain the balls used in the main match, but no new balls. The team fielding first in the eliminator shall have first choice of ball. The team fielding second may choose to use the same ball as chosen by the team bowling first. If the ball needs to be changed, then playing conditions as stated for the main match shall apply.
