What each standard or directive actually requires, where it stops, and what it means for the equipment you specify. Written against the documents themselves rather than against a brochure.
ISO 21069 is the reason two inspection stations can be expected to return the same braking figure for the same truck. It does not set a pass mark. It sets the test method, the conditions under which the test is valid, and the data the instrument has to produce.
Read moreR13 and R13-H approve the braking system of a vehicle type. They do not approve a brake tester and they do not set the inspection procedure for a vehicle already on the road. Buyers mix the two constantly, and it leads to equipment specified for a test it will never perform.

Read moreA brake tester that has drifted is worse than no tester, because it produces confident numbers that cannot be defended. Calibration is the only thing standing between a measurement and a claim.
