Full title and description

St ISO 19074-2015 — Leather — Physical and mechanical tests — Determination of water absorption by capillary action (wicking). This standard specifies a laboratory method for measuring the rate and extent to which leather absorbs water by capillarity (wicking), reporting both the wicking distance and the percentage mass gain under defined conditions.

Abstract

ISO 19074:2015 defines a vertical immersion test in which a strip of leather is partially immersed in water and, after a fixed time (120 ± 5 minutes), the highest water front (wicking height) and the mass increase of the specimen are measured. The method is intended for use on all types of leather and includes specimen preparation, conditioning, apparatus, test execution and result calculation.

Scope

ISO 19074:2015 specifies a test method for determining the rate of absorption of water by capillary action (wicking) in leather. It is applicable to all types of leather. The standard sets out specimen dimensions and orientation, conditioning and thickness measurement references, required apparatus (beaker/container, balance, ruler, specimen holders), test procedure (vertical immersion and 120 ± 5 min duration) and reporting of wicking distance(s) and percentage mass gain.

Key topics and requirements

• Principle: vertical partial immersion of a leather strip; measurement of maximum water front (wicking height) and mass gain after the test interval (120 ± 5 minutes).
• Specimen preparation: typical specimen size and orientation requirements (parallel and perpendicular to backbone) and conditioning per ISO 2419; thickness measurement per ISO 2589.
• Apparatus and materials: low-form beaker or container, balance (accuracy < 0.01 g), ruler, specimen holders, optional metal mass to prevent rolling, and laboratory water conforming to ISO 3696.
• Measurements and calculations: wicking distances on grain/flesh/lateral sides, and water absorption A calculated as ((m1 − m0) / m0) × 100 % (mass-based percentage increase).
• Reporting: test conditions, specimen orientation, wicking heights, mass before/after, calculated absorption percentage and any deviations from normative references.

Typical use and users

Tanners, leather manufacturers, quality control and testing laboratories, research institutes and product specifiers use ISO 19074:2015 to assess capillary water uptake of leather for process control, product development, incoming material inspection and comparative specification. The method supports material performance characterization where surface/lateral wicking and water uptake are relevant to end-use (footwear, garments, upholstery, technical leathers).

Related standards

Normative and related references frequently cited with ISO 19074 include ISO 2418 (sampling location for leather tests), ISO 2419 (sample preparation and conditioning), ISO 2589 (thickness determination) and ISO 3696 (water for analytical laboratory use). National/adopted versions (for example EN/UNI adoptions) may exist. The method was prepared by the IULTCS/IUP commission and is identified also as IULTCS/IUP 57:2015 in the originating body’s documentation.

FAQ

Q: What is this standard?

A: ISO 19074:2015 is an international test method titled "Leather — Physical and mechanical tests — Determination of water absorption by capillary action (wicking)". It defines how to measure capillary water uptake in leather specimens.

Q: What does it cover?

A: It covers specimen preparation and conditioning references, required apparatus, the vertical partial-immersion test procedure (120 ± 5 minutes), measurement of wicking height(s) and mass gain, calculation of percentage water absorption and reporting requirements.

Q: Who typically uses it?

A: Tanning and leather manufacturing quality/control labs, independent test houses, research organisations and product developers who need to characterise or specify leather water uptake by capillarity.

Q: Is it current or superseded?

A: ISO 19074 was published in September 2015 (first edition). According to ISO bibliographic information it was reviewed under the ISO review cycle and retained as current at the last review; users should check with their national body or ISO catalogue for any subsequent amendments or withdrawals.

Q: Is it part of a series?

A: While not a multi-part series itself, ISO 19074 belongs to the family of ISO/IULTCS leather physical and mechanical test methods and is used alongside related leather test standards (ISO 2418, ISO 2419, ISO 2589, etc.). It is also recorded as IULTCS/IUP 57:2015 in IULTCS documentation.

Q: What are the key keywords?

A: Wicking, capillary action, water absorption, leather testing, physical tests, wicking height, absorption percentage, IULTCS.
