# Commission Delegated Regulation (EU) 2015/68 of 15 October 2014 supplementing Regulation (EU) No 167/2013 of the European Parliament and of the Council with regard to vehicle braking requirements for the approval of agricultural and forestry vehicles (Text with EEA relevance), Division 3.1.3.3: Hot and cold parking braking performance test

Extent: E+W+S+N.I.

In order to verify that the parking brake is capable of holding a laden tractor on an up and down gradient as required by points 3.1.3.1 and 3.1.3.2, the measurements shall be done under the following conditions:
Heating up the brakes on a temperature ≥ 100 °C (measured at the rubbing surface of the disc or at the outside of the drum),
Hot static parking braking system test at a temperature ≥ 100 °C,
Cold static parking braking system test at a temperature ≤ ambient temperature + 10 °C,
During the cooling period, the parking braking system shall not be re-adjusted manually.
In the case of oil immersed brakes, the method by which this check is carried out shall be agreed between the vehicle manufacturer and the technical service. The method of assessment and results shall be appended to the type approval report.
The hot static parking braking system test may be omitted if the parking braking system acts purely on braking surfaces not used during service braking.
