Full title and description

ISO 17071:2006 — Leather — Physical and mechanical tests — Determination of fogging characteristics. This International Standard specifies two alternative laboratory methods for assessing the tendency of leather (used in motor‑vehicle passenger compartments) to produce condensable volatile deposits ("fogging") on cold surfaces under defined test conditions.

Abstract

ISO 17071:2006 gives two different test procedures (Method A and Method B) to measure volatile components that can condense from leather and form films or droplets on cold surfaces. Method A uses a reflection-based assessment of light scattering/opaqueness from volatiles condensed on a cold glass surface; Method B is a gravimetric procedure that measures the mass of volatile condensate collected on a cold aluminium foil. The two methods are not mathematically interchangeable. Annex A reports inter‑laboratory trial results (noting better repeatability for Method B). The test conditions permit the two methods to be carried out in succession.

Scope

This standard applies to finished leathers intended for use in motor‑vehicle passenger compartments and defines controlled laboratory procedures for determining fogging characteristics caused by volatile substances emanating from leather surfaces. It specifies both an optical/reflection approach (Method A) and a gravimetric collection approach (Method B), describes test atmosphere and temperature conditions, sample preparation and conditioning, and reporting requirements; it also notes that results from the two methods are not directly comparable.

Key topics and requirements

• Definition of fogging and its relevance to passenger‑compartment air quality and visibility.
• Two alternative test methods:
  • Method A — Reflection measurement on cold glass (light scattering/opaqueness and nature of film/droplet formation).
  • Method B — Gravimetric measurement of condensate collected on cold aluminium foil (mass of volatiles).
• Detailed apparatus and conditioning requirements (cold surface holders, temperature control, specimen mounting).
• Sample preparation, preconditioning and sequence — test conditions allow carrying out Method A and Method B in succession on the same specimen set.
• Inter‑laboratory performance notes (Annex A) — Method B reported as more repeatable in trials, Method A showing larger variation in reflection percentages.
• Required reporting elements: method used, environmental/test conditions, numerical results (reflection percentage or condensate mass), and any deviations from the procedure.

These topics are presented in the standard text and supporting annex.

Typical use and users

Typical users include automotive OEMs and specifiers, leather tanneries and finishers, independent testing laboratories, quality assurance teams, materials engineers, and regulatory or certification bodies concerned with interior air quality and visibility performance. The standard is used to evaluate and compare leather finishes, to support product development and quality control, and to provide data for supplier declarations and purchasing specifications.

Related standards

ISO 17071 is part of the body of ISO/IULTCS standards on leather testing. Related and frequently cross‑referenced standards include other ISO leather physical, mechanical and chemical test methods (for example, standards for chromium(VI) determination and other leather chemical/physical tests maintained under IULTCS/ISO technical committees). Users commonly consult the broader leather test series (ICS 59.140.30) for complementary methods.

FAQ

Q: What is this standard?

A: ISO 17071:2006 is an International Standard that specifies laboratory test methods for determining the fogging characteristics of leather intended for use in motor‑vehicle passenger compartments (two alternative methods: reflection and gravimetric).

Q: What does it cover?

A: It covers sample preparation and conditioning, apparatus and controlled test conditions, two alternative test procedures (Method A — optical/reflection on cold glass; Method B — gravimetric collection on cold aluminium foil), performance notes from inter‑laboratory trials, and reporting requirements. The methods measure different properties and their results are not directly interchangeable.

Q: Who typically uses it?

A: Automotive manufacturers, leather suppliers, testing and accreditation laboratories, product developers and QA teams use the standard to evaluate leather finishes for interior use and to support procurement and conformity assessments.

Q: Is it current or superseded?

A: ISO 17071:2006 was published in 2006 and has been subject to ISO periodic review; the ISO bibliographic record shows the standard as published and confirmed in periodic reviews (confirmed in recent ISO reviews). Users should check national bodies or ISO for the absolute current status if a compliance decision depends on the latest review.

Q: Is it part of a series?

A: Yes — it belongs to the group of ISO/IULTCS standards covering leather physical, mechanical and chemical tests (ICS 59.140.30). It is maintained within the portfolio of leather test methods developed under the IULTCS/ISO technical committee.

Q: What are the key keywords?
