ISO 10326-1:2016 specifies basic requirements for the laboratory testing of vibration transmission through a vehicle seat to the occupant. These methods for measurement and analysis make it possible to compare test results from different laboratories for equivalent seats. It specifies the test method, the instrumentation requirements, the measuring assessment method and the way to report the test result. ISO 10326-1:2016 applies to specific laboratory seat tests which evaluate vibration transmission to the occupants of any type of seat used in vehicles and mobile off-road machinery. Application standards for specific vehicles refer to this document when defining the test input vibration that is typical for the vibration characteristics of the type or class of vehicle or machinery in which the seat is to be fitted. NOTE Examples of application standards are given in the bibliography.
