除了ISO 15550中定义的基本要求外，ISO 3046-3:2006还规定了往复式内燃机主要性能参数的通用测量技术。这是为了确保达到所需的测量精度，以便将测量值与发动机制造商规定的值进行比较。必要时，可针对特定发动机应用给出单独要求。 ISO 3046-3:2006适用于陆上、轨道牵引和海上使用的往复式内燃机。 它可应用于用于推动道路施工机械、工业卡车的发动机，以及没有适用于这些发动机的国际标准的其他应用。

ISO 3046-3:2006 specifies the common measurement techniques of the main performance parameters of reciprocating internal combustion engines, in addition to the basic requirements defined in ISO 15550. This is to ensure that the required accuracy of measurement is achieved for comparison of the measured values with those values specified by the engine manufacturer. Where necessary, individual requirements may be given for particular engine applications. ISO 3046-3:2006 applies to reciprocating internal combustion engines for land, rail-traction and marine use. It may be applied to engines used to propel road construction machines, industrial trucks and for other applications where no suitable International Standards for these engines exist.
