Full title and description

ISO 10326-1:2016 Mechanical vibration — Laboratory method for evaluating vehicle seat vibration — Part 1: Basic requirements. This International Standard specifies the basic laboratory requirements to measure and report vibration transmission through a vehicle seat to the occupant, enabling comparable results between laboratories and consistent reporting of seat vibration test data.

Abstract

Specifies a laboratory test method, instrumentation and calibration requirements, measurement and assessment methods, and reporting formats for evaluating how vibration is transmitted through vehicle seats to occupants. The document applies to seats used in road vehicles, railway vehicles, agricultural and earth‑moving machinery and is intended to be referenced by application standards that define the appropriate input vibration for a given vehicle class.

Scope

Applies to laboratory tests that evaluate vibration transmission from a vehicle seat to its occupant for any type of seat used in vehicles and mobile off‑road machinery. The standard defines the test input / excitation conventions (as referenced by vehicle‑type application standards), the required instrumentation and calibration, measurement points and assessment procedures and the reporting content needed to allow inter‑laboratory comparison.

Key topics and requirements

• Definition of test method and required test sequences for seat vibration transmission (including frequency ranges and types of excitation used or referenced by application standards).
• Instrumentation requirements and calibration procedures (requirements reference ISO 8041 for frequency weighting and ISO 16063‑1 for transducer calibration and related calibration parts where applicable).
• Mounting locations and methods for accelerometers (platform/floor reference accelerometer and seat pad/backrest interface accelerometers; semi‑rigid mounting guidance and alignment tolerances are specified).
• Vibration simulator and platform performance requirements (frequency response, acceptable cross‑axis motion, lowest acceptable resonance frequency and compensation/control of test system to achieve the specified PSD/PDF of the input vibration).
• Measurement outputs and assessment: frequency response functions, SEAT‑factor/seat transmission metrics, use of appropriate frequency weighting and reporting formats to enable comparison between seats and laboratories.

Typical use and users

Used by test laboratories, seat and vehicle manufacturers (road, rail, agricultural and construction equipment), regulatory bodies and standards developers to characterise and compare seat dynamic behaviour, to validate seat design for occupant comfort and to support application standards that specify vehicle‑type input vibrations. Test engineers and acoustic/vibration specialists use the standard when planning and performing laboratory seat tests.

Related standards

FAQ

Q: What is this standard?

A: ISO 10326‑1:2016 is an ISO International Standard that specifies basic laboratory requirements for measuring and reporting vibration transmission through vehicle seats to occupants.

Q: What does it cover?

A: It covers the test method, instrumentation and calibration requirements, mounting and measurement points, assessment methods (including frequency weighting and how to determine seat transmissibility/SEAT factors) and the reporting format needed to compare results between laboratories.

Q: Who typically uses it?

A: Test laboratories, vehicle and seat manufacturers, design and NVH engineers, certification bodies and standards committees working on occupant comfort and vibration evaluation for road, rail, agricultural and earth‑moving vehicles.

Q: Is it current or superseded?

A: ISO 10326‑1:2016 (corrected in early 2017) is the published (current) edition replacing the 1992 edition and its amendments; ISO indicates it is maintained under the periodic review cycle. Users should check their national or the ISO catalogue for any later revisions or amendments before use.
