Division 4 PROCEDURE FOR THE ALIGNMENT OF A REFERENCE LABORATORY TO THE ASSIGNED VALUESF1

United Kingdom

Original text. Later amendments are not shown.

Each reference laboratory ( l ) shall align itself to the assigned values of the alignment tyre set using a linear regression technique, A1 l and B1 l , calculated as follows:

RRC = A1 l * RRC m,l + B1 l

where:

RRC

  • is the assigned value of the rolling resistance coefficient;

    • RRC m,

  • is the measured value of the rolling resistance coefficient by the reference laboratory ‘ l ’ (including temperature and drum diameter corrections)
