Road vehicles — Open Test sequence eXchange format (OTX) — Part 4: Expanded extensions interface definition
Scope:
This document defines the Open Test sequence eXchange (OTX) additional extension requirements and data model specifications.
The requirements are derived from the use cases described in ISO 13209-1. They are listed in Clause 4.
The data model specification aims at an exhaustive definition of all features of the OTX extensions which have been implemented to satisfy the requirements. This document establishes rules for the syntactical entities of each extension. Each of these syntactical entities is accompanied by semantic rules which determine how OTX documents containing extension features are interpreted. The syntax rules are provided by UML[2] class diagrams and XML schemas, whereas the semantics are given by UML activity diagrams and prose definitions.

Mechanical vibration — Laboratory method for evaluating vehicle seat vibration — Part 3: Specification of dynamic dummies for Z-axis motion
Scope:
This document specifies dynamic dummies used as replacements for participants in vibration tests of vehicle seats in laboratory.
This document is applicable to seats installed in earth-moving machinery, agricultural wheeled tractors, and industrial trucks.
This document specifies technical requirements, acceptance criteria, and a validation test for dynamic dummies representing the human body in two mass groups: lightweight (52 kg to 55 kg) and heavyweight (98 kg to 115 kg). It only applies to passive and active dynamic dummies used for vibration tests of vehicle seats in the Z-axis (vertical) direction.
This document defines, for the two mass groups, the biodynamic response characteristics that the dynamic dummies are required to reproduce to represent those of the participants to be replaced. This document gives guidance on conducting future research to explore the degree of convergence that can be reached when the dynamic performance of seats is measured with participants and with dynamic dummies conforming to this document.
NOTE 1 For seat testing, results have shown that the benefit of using a dynamic dummy is highly dependent on the excitation and dynamic characteristics of the seats. Depending on the type of vibration excitation applied, studies have suggested that the use of dynamic dummies can show benefit over an inert mass of equivalent weight only when testing suspension seats with higher natural frequency (>2 Hz).
NOTE 2 The use of dynamic dummies has been reported to tend to overestimate the vibration isolation performance of seats compared with that measured with participants. Several factors can be in cause and require further investigation, one of them being the influence of the legs possibly not being adequately considered when using dynamic dummies.
