This document defines visual aspects for the identification and assessment of product characteristics for friction materials in terms of quality and for commercial and technical agreements. The sequence of the product characteristics represents no order of priority. Inspection is carried out in unused, “as supplied” condition. In some characteristic features, there are differences between brake linings with an effective lining pad area less than 120 cm2 and larger than 120 cm2. The acceptance criteria ensure exclusion of any characteristics that could impact the function and performance of brake linings and applies unless other agreements between the customer and the supplier.
Abstract
Overview
ISO 22574:2023 - Road vehicles - Brake linings friction materials - Visual inspection defines the visual criteria used to identify and assess product characteristics of brake friction materials for quality control and for commercial and technical agreements. Inspection is performed on unused, “as supplied” products. The standard covers disc brake pads, drum brake linings and bonded lined shoes, and for the first edition includes product characteristics of metal lining carriers (backing plates, bonded shoes). Acceptance criteria are intended to exclude any visual defects that could affect the function or performance of brake linings, unless alternate customer–supplier agreements are made.
Key Topics and Requirements
- Scope and intent: Visual aspects for identification and assessment of friction materials; sequence of characteristics is not a priority order.
- Inspection condition: Visual inspection in the unused, “as supplied” state.
- Size-based differences: Some criteria differ for disc pads with effective lining area
