Test methods for road test lanes and parking ramps of motor vehicle inspection agency

1 Scope

GB/T 47274-2026 is the Chinese national standard covering the test lane and the parking ramp of a vehicle inspection station - the gradient, the surface and its friction, the dimensions and the markings, and how each is verified, because the brake and parking tests are only valid on ground that is what it claims to be. First edition, in force since 1 October 2026. It was issued on 31 March 2026 and takes effect on 1 October 2026, as a first edition. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the testing equipment, testing conditions, testing methods, handling of testing results for road test lanes and parking ramps of motor vehicle inspection agencies. This document is applicable to the testing of road test lanes and parking ramps of motor vehicle inspection agencies.
