52.—(1) —U.K.
(a)Except in the case of a dipstick tested by reference to a calibration chart as mentioned in paragraph (2) below, a dipstick associated with a compartment shall be tested by inserting into, or withdrawing from, the compartment known volumes of liquid and determining the position of the scale mark on the dipstick when the road tanker is on a level surface
(b)The known volumes in paragraph (a) above shall be determined using—
(i)local standards of capacity; or
(ii)a reference meter; or
(iii)other equipment, being measures of capacity forming part of a fixed installation or being mounted on a vehicle or trailer, which has been tested in a manner which the inspector considers suitable, and adjusted, within the last twelve months, so as not to have any apparent error.
(2) A dipstick associated with a compartment may be tested by comparing the distance of every scale mark from the datum surface with that given on the calibration chart in respect of the compartment, unless any alteration, addition, damage or repair has been effected to the compartment which in the opinion of the inspector has invalidated the calibration chart, in which case the inspector shall not use a calibration chart to test a dipstick until a new calibration chart has been prepared.
(3) On testing a dipstick associated with a compartment an inspector shall inspect the compartment unless the calibration chart was prepared not more than 42 days before testing, in which case testing may be carried out with the dipstick and calibration chart only being present.
(4) Not more than two dipsticks relating to a compartment forming part of a dipstick measuring system may be passed as fit for use for trade on any one occasion.
