GB/T 18169-2023Specifications of amusement rides bumper car category (English PDF)

Foreword

This document was issued on 23 May 2023 by the State Administration for Market Regulation; Standardization Administration of the PRC and takes effect on 1 September 2023.

It is a GB/T standard: recommended rather than compulsory, but it is the text a Chinese reviewer applies when assessing a submission.

1 Scope

GB/T 18169-2023 covers bumper car amusement rides, from the design of the machine to the documents that travel with it. General requirements tie the ride back to GB 8408 and reach across design, manufacture, installation, modification, repair, testing and inspection. The technical clause is the body of the document: the frame, which is metal and must carry no exposed sharp edges, corners, burrs or dangerous protrusions where riders put their hands; the ride system; the electrical control system, which on these machines distributes power through surfaces the public stands beside; the parking lot; the surface protection, meaning the bumper ring that turns a collision into a nudge; emergency rescue; the complete machine; and the requirements that apply separately to each type of bumper car, the pole-mounted type among them. Test methods set out the inspection plans the manufacturing and installing organisations draw up against the design documents, and the specific procedure for each item. The last clause fixes accompanying documents, product nameplate, marking, packaging, transportation and storage. The detail exists because this is a ride whose whole purpose is deliberate collision, driven by untrained members of the public and often by children. For ride manufacturers, park and arcade operators, installers and the inspection bodies that release the ride into service.

This Document specifies the overall requirements, technical requirements, test methods,

random documents, product nameplates, marking, packaging, transportation and storage of

amusement rides bumper car.

This Document applies to the design, manufacturing, installation, modification, maintenance,

testing, inspection and use management of amusement rides bumper car.
