The efforts of the ISO “Test Variability Task Force” have been aimed at improving the understanding and at reducing brake dynamometer performance test variability. In addition, dynamometer test results have been compared and correlated to vehicle testing. This paper focuses on assessing friction levels, friction coefficient sensitivity, and repeatability under ECE, GB, ISO, JASO, and SAE laboratory performance tests. With multiple companies (or programs) developing and assessing the friction coefficient and friction behavior under different methods, it is inevitable to avoid conflicts of performance requirements or lack of reproducibility or correlation of test results under different test methods. In order to provide an evaluation consistent with previous phases of the Task Force activities, the same brake corner assembly and same friction material is used for this study. The study is comprised of three main steps: (a) Conducting tests under several test procedures: • ISO 26867:2009 — Friction Behaviour Assessment for Automotive Brake Systems (two samples) • SAE J2522:2013 — Dynamometer Global Brake Effectiveness (two samples) • SAE J2784:2009 — FMVSS Inertia Dynamometer Test Procedure for Vehicles Below 4 540 Kg GVWR (two samples) • JASO C406:2000 — Passenger Car — Dynamometer Test Procedures (two samples) • ECE R90-02:2013-Annex 9 – Part A— Determination of friction behaviour by machine testing (three samples) • SAE J661:2012 — Brake Lining Quality Control Test Procedure (five samples) • GB 5763:2008 — Brake Linings for Automobiles (TBD samples) all dynamometer tests were conducted using the same inertia dynamometer to eliminate the reproducibility (dyno-to-dyno) component in the total variability evaluation.
