ISO/FDIS 14419

• Abstract:

  This document specifies a method for the evaluation of a substrate's resistance to absorption of a selected series of liquid hydrocarbons of different surface tensions. This document provides guidance to oil stain resistance. It can provide a rough index of oil stain resistance as, generally, the higher the oil repellency grade, the better resistance to staining by oily materials, especially liquid oil substances. This is particularly true when comparing various finishes for a given substrate. This document can also be used to determine if washing and/or drycleaning treatments have any adverse effect on the oil repellency characteristics of a substrate. NOTE 1 Washing and drycleaning treatment procedures are described in ISO 6330 and ISO 3175 (all parts), respectively. This document is not intended to give an absolute measure of the resistance of the substrate to staining by all oily materials. Other factors, such as composition and viscosity of the oily substances, substrate construction, fibre type, dyes and other finishing agents, also influence stain resistance. This document is not intended to estimate the resistance to penetration of the substrate by oil-based chemicals. NOTE 2 For the evaluation of the resistance to penetration of the substrate by oil-based chemicals, see ISO 6530.

ISO/FDIS 14419 from ISO specifies a laboratory method for judging how a textile substrate resists absorption of a selected series of liquid hydrocarbons. It gives an oil repellency grade that serves as a practical index of staining resistance to oily liquids, especially when comparing finishes on the same substrate. The method is also used to check whether washing or drycleaning changes that repellency.

What does ISO/FDIS 14419 specify?

ISO/FDIS 14419 specifies a hydrocarbon resistance test for textiles, with the result reported as an oil repellency grade. The method is intended for comparing substrates and finishes, and for checking the effect of washing or drycleaning on repellency.

The document is organized into clauses for scope, references, terms, principle, safety, reagents and materials, apparatus, test specimens, procedure, evaluation, evaluation of results, and test report. Annex A gives the precision and bias statement.

Annex	What it covers
A	Precision and bias statement

What are the key requirements of ISO/FDIS 14419?

ISO/FDIS 14419 bases the result on which numbered hydrocarbon liquid first wets the substrate, so the test is a graded comparison rather than a pass/fail check. In practice, the tester must control the liquids, the atmosphere, the specimen preparation, and the reading time carefully, because small handling differences can change the grade.

Test principle and grading

Clause 4 places drops of standard test liquids on the surface and watches for absorption, wicking, and contact angle. The oil repellency grade is the highest numbered liquid that does not absorb into the substrate within the set observation time.

That means the test shows relative repellency to a defined liquid series, not resistance to every oily material. The scope also notes that substrate construction, fibre type, dyes, and finishing agents can all affect the result.

Safety and handling

Clause 5 treats the hydrocarbons as flammable laboratory materials. The document calls for good laboratory practice, safety glasses, impervious gloves, ventilation, and keeping the liquids away from heat, sparks, and open flame.

Reagents, materials, and apparatus

Clause 6 requires analytical-grade reagents and standard test liquids stored at the specified temperature. The liquid series is numbered, and the table defines the liquids used for grading, including white mineral oil and n-heptane in the series.

Clause 7 requires marked dropping bottles and warns against silicone contamination. In practice, this matters because silicone can alter wetting and give misleadingly high grades.

Test specimens and procedure

Clause 8 uses three specimens of about 35 cm by 35 cm, conditioned before testing in the ISO 139 atmosphere. Clause 9 places drops at five locations, observes each drop for 30 seconds, and continues through the liquid series until wetting or wicking appears.

For napped or pile fabrics, the surface is brushed first in the direction of greatest lay. For open-weave or thin substrates, extra layers are placed underneath so the backing does not create a false result.

Evaluation and reporting

Clause 10 defines pass, borderline pass, and fail by the appearance of the five drops. A grade of zero is used when the specimen fails with white mineral oil, and borderline cases are reported in half-grade steps.

Clause 11 requires two determinations, with a third if the first two disagree. The reported value is the matching result, or the median when three results differ. Clause 12 requires the report to identify the sample, number of specimens, atmosphere, deviations, results, grade, and date.

What terms does ISO/FDIS 14419 define?

• Grade - a step on the standard reference scale; here it is the reported oil repellency rating.
• Oil repellency - the characteristic of a fabric that resists absorption of oily liquids.
• Standard test liquids - the numbered hydrocarbon liquids used to challenge the substrate in sequence.
• White textile blotting paper - the absorbent backing used under the specimen to make wetting easier to see.
• Borderline pass - a result where the drop remains rounded but shows partial darkening at the interface.
• CAS RN - Chemical Abstracts Service Registry Number, the identifier used for white mineral oil.
• Analytical grade - the reagent quality required for the test liquids and other reagents.
• Test specimen - the conditioned piece of substrate that is actually tested.

Who uses ISO/FDIS 14419?

ISO/FDIS 14419 is used by textile testing laboratories, textile manufacturers, finish suppliers, quality teams, and buyers who compare oil-repellent finishes. It is also used when checking whether domestic washing, professional cleaning, or finishing treatments have changed repellency.

In practice, these users apply the method to compare finishes on the same fabric, verify product claims, and investigate variation between specimens. It is most useful where oily staining is a concern and a simple, repeatable laboratory index is needed.

What changed in ISO/FDIS 14419 from the previous edition?

ISO/FDIS 14419 states that this fourth edition cancels and replaces ISO 14419:2025, with technical revision only. The main change is in Clause 6.2, Table 1, where the liquid list was corrected to align with ISO 14419:2010 edition 2 and n-heptane was reinstated.

Which standards are used with ISO/FDIS 14419?

ISO/FDIS 14419 names ISO 139 as the conditioning and testing atmosphere reference. That standard contributes the controlled temperature and relative humidity used before and during testing.

The bibliography also names ISO 6330, ISO 3175-1 to ISO 3175-6, and ISO 6530. ISO 6330 and the ISO 3175 series are used when checking the effect of washing or drycleaning treatments, while ISO 6530 is the reference for resistance to penetration by oil-based chemicals, which is a different property from repellency.

What does the ISO/FDIS 14419 document contain?

ISO/FDIS 14419 contains a full laboratory method, including the principle, safety precautions, reagent list, apparatus, specimen preparation, procedure, evaluation rules, result handling, and reporting items. It also includes Table 1 for the standard test liquids and Figure 1, which illustrates pass, borderline pass, and fail appearances.

Annex A provides the precision and bias statement, based on interlaboratory studies. That section is useful when comparing results between operators or laboratories and when judging whether two grades are meaningfully different.

de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.

PROJET FINAL Norme internationale ISO/FDIS 14419:2026(fr)
Textiles — Oléofugation — Essai de résistance aux
hydrocarbures
1 Domaine d'application
Le présent document spécifie une méthode d'évaluation de la résistance d'un substrat à la pénétration par
une série d'hydrocarbures liquides sélectionnés présentant des tensions de surface différentes.
Le présent document fournit des recommandations relatives à la détermination de la résistance aux taches
d'huile. Il peut servir d'indice approximatif de la résistance aux taches d'huile dans la mesure où, de manière
générale, la résistance au tachage par des matériaux huileux, en particulier des substances huileuses
liquides, est d'autant plus grande que la classe d'oléofugation est élevée. Cela se vérifie en particulier lors de
la comparaison des divers apprêts ou finissages d'un substrat donné. Le présent document peut également
être utilisé pour déterminer si les traitements de lavage et/ou de nettoyage à sec ont des effets défavorables
sur les caractéristiques d'oléofugation d'un substrat.
NOTE 1 Des traitements appropriés de lavage et de nettoyage à sec sont décrits dans
[1] [2] [3] [4] [5] [6] [7]
l'ISO 6330, l'ISO 3175-1, l'ISO 3175-2, l'ISO 3175-3, l'ISO 3175-4, l'ISO 3175-5 et l'ISO 3175-6 .
Le présent document n'a pas pour objet de fournir une mesure absolue de la résistance des substrats au
tachage par tous les matériaux huileux. D'autres facteurs, tels que la composition et la viscosité des
substances huileuses, la conception des substrats, le type de fibre, les colorants et autres agents d'apprêt
ou de finissage, influent également sur la résistance aux taches. Le présent document n'est pas destiné à
l'évaluation de la résistance du substrat à la pénétration par des produits chimiques à base d'huile.

classe, nom
valeur que peut prendre n'importe quel échelon d'une échelle de référence normalisée pour les
caractéristiques liées à la qualité
Note 1 à l'article: Cette valeur est attribuée aux éprouvettes présentant un degré de qualité comparable à l'échelon de
l'échelle de référence normalisée.
3.2
oléofugation, nom
aptitude d'une étoffe à résister à la pénétration par des liquides à base d'huile
4 Principe
Des gouttes de liquides d'essai normalisés, issus d'une série d'hydrocarbures sélectionnés présentant des
tensions de surface différentes, sont déposées à la surface du substrat. La pénétration des gouttes, l'effet
de mèche et l'angle de contact sont ensuite observés. La classe d'oléofugation du substrat correspond au
numéro de liquide d'essai le plus élevé parmi les liquides d'essai n'ayant pas été absorbés par le substrat.
