Amusement parks in India are becoming quite common and people visit these parks quite often. In order to ensure their safety in amusement parks or while enjoying the rides, an attempt has been made to stipulate safety in the form of a National Code. It is hoped that organizers of amusement parks, manufacturers of rides would make use of these codes to ensure overall safety of human beings and equipment at such places. The code of recommended practice for amusement rides safety is being brought out in six parts. This standard covers the necessary performance tests for amusement rides. The other parts in this series are as follows: Part 1 Part 2 Part 3 Part 4 Part 5 General information Safety requirements Design, manufacture and erection Selection, training and supervision of operators Operation and maintenance procedures (Continued on third cover)

It is the responsibility of the user of this Code to establish appropriate safety and health practices and comply with regulatory and statuatory requirements prior to use of the ride or device for carrying passengers for their amusement. 2 REFERENCES The following standards contain provisions, which through reference in this text, constitute provision of this standard.
