Reciprocating internal combustion engines — Measurement of sound power level using sound pressure — Part 2: Survey method
This document specifies the survey method, which is the measurement method of the sound power level for reciprocating internal combustion engines. This document applies to all reciprocating internal combustion engines falling within the field of application of ISO 3046‑1 and other internal combustion engines where no suitable International Standard exists. NOTE In this document, reciprocating internal combustion engines are referred to as engines unless otherwise explained.
ISO 6798-2:2020 - "Reciprocating internal combustion engines - Measurement of sound power level using sound pressure - Part 2: Survey method" specifies a standardized survey method to measure the sound power level of reciprocating internal combustion engines using sound pressure on an enclosing measurement surface. It applies to engines covered by ISO 3046‑1 and other internal combustion engines where no specific international standard exists. The survey method delivers an A-weighted sound power result with accuracy grade 3 and results rounded to 0.1 dB.
