Howard, I googled the following information:
Quote:
Regulation No.115 :
R115 is a European retrofit directive for LPG and CNG systems, as of October 2003. This directive stipulates the emission, documentation and quality standards to be met by the manufacturer of the LPG system. For each car make or car make series vehicles have to be tested in a certified laboratory. The following checks will be made during these tests:
Parent car check:
Emission measurements:
The vehicle is measured when using petrol (1x) and LPG (at least 2x). For the LPG test two reference fuels are used (LPG-A = 85% propane-15% butane and LPG-B= 30% propane-70% butane). The power per cylinder will be calculated for the parent vehicle. The R115 certification results in a range of vehicles within 30% below and 15% above this value. Depending on car make or car make series, at least 1 or 2 vehicles will have to be tested. The R115 certification is based on the Euro standard of the vehicle tested (current vehicles comply with Euro 4 standard).
Power measurement:
For each parent vehicle the power has to be measured on petrol and LPG/CNG. When running on LPG or CNG, the power should not increase more than 5%.
Fuel consumption:
For each parent vehicle the fuel consumption on LPG/CNG is calculated based on the CO2 emission measured.
OBD function check:
For each parent vehicle an OBD function check of the petrol and LPG/CNG system is made. The installed LPG or CNG system should not influence the operation of the OBD system.
Installation according to R67-01 or R110:
The R67-01 (LPG) and R110 (CNG) directives describe the use of certified components and system installation requirements. These directives have already been used in Europe for a few years. The parent vehicles will be tested based on those directives (components and installation).
Documentation:
In addition to the parent vehicle requirements, the following documentation must be provided with the LPG or CNG system according to the R115 directive:
Instruction manual (service booklet) in the appropriate language.
Installation instructions for the workshop (at least in English).
Identification sticker or label to be installed in engine compartment.
ISO / quality assurance:
The LPG or CNG system manufacturer will be tested according to the corresponding ISO standard and quality assurance program for the components (C.O.P.). This certification will be carried out by a certification board which acknowledges the R115 certification, e.g. RDW in the Netherlands or KBA in Germany.
