GB 16170-1996Limits of noise emitted by stationary road vehicles (English PDF)

GB 16170-1996 is the English-translated version of 汽车定置噪声限值.

GB 16170 sets the noise limits for a road vehicle measured standing still, with the engine at a defined speed and the microphone at a fixed position near the exhaust outlet. The stationary test exists because it can be done at a roadside or in a testing station without the space a drive-by test needs, which makes it the method used in periodic inspection and in enforcement against tampered exhausts. Still in force after nearly thirty years. Issued on 7 March 1996 by the State Environmental Protection Administration, in force since 1 January 1997. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the edition it replaces are taken from there. The clause text, the tables and the numeric limits are not reproduced on this page — they are in the document itself, which is delivered in full in English translation.
