With Ireland leading 10-3 at the break in bitterly cold conditions, Scottish referee Kevin White called the game off at half-time for health and safety reasons, with the pitch hardening in the freezing temperatures.
Ireland had scored the only try in the 18th minute through an excellent run from winger Alison Miller, with centre Niamh Briggs adding the conversion.
Wales' Laura Prosser and Briggs swapped penalties in the closing minutes of the half as Ireland moved 10-3 ahead for the break.
With player safety paramount, the decision was taken to halt proceedings prematurely.
The Six Nations sub-committee will meet next week to set a date for a replay between the teams at the same County Meath venue
