Description (English):

ISO 17071:2006 specifies two alternative methods for determining the fogging characteristics of leathers used in the passenger compartments of motor vehicles, namely Method A and Method B. These are two different test procedures to measure the volatile components and there is no mathematical correlation between the results obtained with Method A and those with Method B. Method A determines by reflection the light scattering properties (or opaqueness) and the nature of the film or droplet formation from volatile components condensed on a cold glass surface. Method B measures gravimetrically the quantity of volatile components condensed on a cold aluminium foil surface. Annex A gives the results of inter-laboratory trial which show that Method B performs well, whereas Method A showed a large variation in the percentage reflection. The test conditions allow the two tests to be carried out in succession.

Abstract

Overview

ISO 17071:2006 - Leather - Physical and mechanical tests - Determination of fogging characteristics specifies two accepted laboratory methods to assess the tendency of automotive leathers to produce condensable volatile deposits (fogging) inside motor-vehicle passenger compartments. The standard was prepared by IULTCS/IUP and published by ISO (also issued as EN 14288). It defines Method A (reflectometric) and Method B (gravimetric), explains required apparatus and sample preparation, and includes inter-laboratory trial results showing differences in reproducibility between the methods.

Key Topics

Scope and intent: Measure volatile components emitted from leather that may condense on interior surfaces (windshield-like substrates) and affect visibility or passenger comfort.
Two alternative procedures:
- Method A - Reflectometric method: Volatiles are condensed onto a cold glass plate; the light-scattering (opaqueness) of the condensate is measured by a reflectometer (60° incident/measurement geometry). Result expressed as percentage reflection relative to the clean plate. The method characterizes droplet/film appearance but can be sensitive to film type and shows higher inter-laboratory variability.
- Method B - Gravimetric method: Volatiles are condensed on a cold aluminium foil and measured by weight gain (gravimetric). Annex A reports that Method B performs well in inter-laboratory trials.
Test conditions and apparatus: Includes controlled heating in a thermostatic bath at 100 °C ±1 °C, cooled plate at about 21 °C, float glass plates, metal rings, sealing rings, filter paper, and reference material (e.g., di‑isodecyl phthalate, DIDP) for reference tests.
Sampling and preparation: References ISO 2418 (sampling) and ISO 2419 (sample preparation/conditioning). Cleanliness, desiccation, and handling procedures are specified to minimize contamination and ensure reproducibility.
Important notes: There is no mathematical correlation between results from Methods A and B; results are not directly interchangeable. Tests may be carried out in succession on the same sample.

Applications

Automotive OEMs and suppliers evaluating automotive leather fogging risk for instrument panels and windshields.
Leather tanneries and material engineers conducting quality control for interior leathers.
Independent test laboratories performing compliance and comparative testing for passenger-compartment materials.
Product development teams seeking to reduce volatile emissions from leather finishes and coatings.
