According to section 3.8.6 of the Rescue Maze Rules 2026, it states:
“All measurements in the rules have a tolerance of ±10%.”
Does this tolerance also apply to the dimensions of the rescue kit?
The rules specify that each side of the rescue kit must be at least 1 cm.
Would a cube with a side length of 9 mm be considered acceptable under this tolerance?
Very smart question. I am curious about the answer. I will follow.
Dear @shuji4649
The ±10% tolerance in Section 3.8.6 is intended to account for measurement uncertainty and small material variances. However, the rescue kit rule also states:
Each rescue kit must have a minimum size of 1 cm in each dimension and a minimum volume of 1 cm³ after deployment.
So even if you consider the ±10% tolerance when checking the minimum, teams must still satisfy both requirements (dimensions and volume).
A 9 mm × 9 mm × 9 mm cube has a volume of 0.729 cm³, which is below the minimum volume requirement (and also below the “minimum with tolerance” interpretation). Therefore, a 9 mm cube is not acceptable.
We encourage teams that this is risky, as they are going to the limits. If only 0.5mm is missing from one of the measures, it will be enough to make it an invalid kit, so it’s recommended to use the tolerance in your favor in case of material variances.
