The amendments will also be trialled in the southern Hemisphere from the start of next season.
Participants will be asked to complete a simple online questionnaire to voice their opinions on the law trials, which include limiting the time that the ball is available at the back of a ruck and the scrum engagement sequence.

The consolidated feedback will play a significant role in what is a truly collaborative evaluation and feedback process, culminating in recommendations being made by the IRB Rugby Committee to the IRB Council at its May 2014 meeting.
Any approved law changes would then be implemented immediately around the world.
IRB Chairman Bernard Lapasset said: "We are committed to being fully collaborative in obtaining views on the law amendment trials that are currently underway in the northern Hemisphere.
"Rugby is an inclusive sport and we want to obtain the views of players, match officials, coaches and of course fans at all levels of the game to see what they like and what they don't.
"We want to make the game as enjoyable to play as possible and this important feedback will be considered by the Laws Review Group and the IRB Rugby Committee."
