The Hardness Tester for Steering Wheels is specifically designed to evaluate the comfort and tactile feel of automotive steering wheels. It measures the elasticity and softness of steering wheel materials to ensure compliance with premium comfort standards. This device has been adopted by multiple European automotive manufacturers and is compatible with most passenger car steering wheels. Optional center positioning and auxiliary support brackets enable accurate measurement on irregular-shaped steering wheels.
Application
(1) Steering wheel material testing: leather, PUR foam, composite materials.
(2) Automotive interior tactile assessment: evaluate touch and comfort of steering wheels in passenger and luxury vehicles.
(3) Product R&D and quality control: new material formulation optimization and batch consistency verification.
(4) Comfort evaluation: ensure ergonomic grip and tactile satisfaction.
(5) Multi-model compatibility: supports various diameters, thicknesses, and structures of steering wheels.
(6) Standardized measurement: suitable for fast hardness and elasticity testing on production lines.
(7) Reference industry usage: steering wheel tactile R&D and quality control.
Standards
(1) PV 3931 – Steering Wheel Hardness Testing Standard.
Note: Can be combined with internal manufacturer standards in accordance with PV 3931.
