A meter shall be considered accurate if, when tested, it registers not to exceed 5% more or 5% less than the actual quantity of water passing through it. If a meter registers in excess of 5% more than the actual quantity of water passing through it, it shall be considered “fast” to that extent. If a meter registers in excess of 5% less than the actual quantity of water passing through it, it shall be considered “slow” to that extent.
