Textiles - Oil repellency - Hydrocarbon resistance test (ISO 14419:1998)
Is used in the evaluation of a substrate's resistance to absorption of a selected series of liquid hydrocarbons of different surface tensions. Is intended to provide a guide to oil stain resistance. It can provide a rough index of oil stain resistance in that 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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 14419 was prepared by ISO Technical Committee ISO/TC 38, Textiles, Subcommittee
SC 2, Cleansing, finishing and water resistance tests.
Annex A of this International Standard is for information only.

Textiles — Oil repellency — Hydrocarbon resistance test
1 Scope
This International Standard is used in the evaluation of a substrate’s resistance to absorption of a selected series of
liquid hydrocarbons of different surface tensions.
This International Standard is intended to provide a guide 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 International Standard can also be utilized in determining if washing and/or dry cleaning treatments have any
adverse effect on the oil repellency characteristics of a substrate. It is recommended that the washing and/or dry
cleaning treatment procedures described in ISO 6330 or ISO 3175 be used for this purpose.
This International Standard 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 International Standard is not
intended to estimate the resistance to penetration of the substrate by oil based chemicals; for this evaluation see
ISO 6530, Protective clothing – Protection against liquid chemicals – Determination of resistance of materials to
penetration by liquids.
2 Normative reference
The following normative document contains provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent edition of the normative document indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of IEC and ISO

3 Definitions
For the purposes of this International Standard, the following definitions apply.
3.1
grade
symbol for any step of a multistep standard reference scale for a quality characteristic
NOTE The grade is assigned to test specimens exhibiting a degree of the quality comparable to that step of the standard
reference scale.
3.2
oil repellency
characteristic of a fabric whereby it resists absorption of oily liquids

4 Principle
Drops of standard test liquids, consisting of a selected series of hydrocarbons with different surface tensions, are
placed on the substrate surface and then observed for absorption, wicking and contact angle. The oil repellency
grade is the highest numbered test liquid which is not absorbed by the substrate surface.
5 Safety precautions
5.1 Good laboratory practices should be followed. Wear safety glasses and impervious gloves when handling test
liquids in all laboratory areas.
5.2 Some of the hydrocarbons specified in this International Standard are flammable. Keep away from heat,
sparks and open flame. Use with adequate ventilation. Avoid prolonged breathing of vapour or contact with skin.
Do not take internally.
NOTE These safety precautions are for information purposes only. The precautions are ancillary to the testing procedures
and are not intended to be all inclusive. It is the user’s responsibility to use safe and proper techniques in handling materials in
this International Standard. Manufacturers should be consulted for specific detail such as material safety data sheets and other
manufacturer’s recommendations.
6 Reagents
All reagents must be of a suitable analytical grade. Ensure the standard test liquids are used and stored at a
temperature of (20 ± 2) °C.
6.1 Test liquids, prepared and numbered according to Table 1.
6.2 White mineral oil, USP white mineral oil 340-355 SSU @ 37,8 °C with Saybolt color + 30.

7 Apparatus
7.1 Dropping bottles, for convenience it is desirable to transfer the test liquids from stock solutions to dropping
bottles, each marked with the appropriate oil test liquid number. A typical system found useful consists of 60 ml
dropping bottles with ground-in pipettes and neoprene bulbs. Prior to use the bulbs should be soaked in heptane
for several hours and then rinsed in fresh heptane to remove soluble substances. It has been found helpful to place
the test liquids in sequential order in a wooden platform on the grading table.
NOTE Purity of test liquids does affect surface tension of the liquid. Use only analytical grades of test liquids.
7.2 White textile blotting paper, textile blotting paper is an absorbent textile blotting paper of 0,71 mm caliper and
2 1)
141,32 g/m blotter sheet weight. White Textile Blotting Paper is available from AATCC.
7.3 Laboratory gloves, general purpose is sufficient.
8 Test specimens
Three test specimens approximately 20 cm · 20 cm are needed. Test specimen size should be chosen to
represent all physical and colour characteristics of the fabric and allow ample room for testing. Condition the test
specimens for a minimum of 4 h at (20 ± 2) °C and (65 ± 2) % RH prior to testing. See ISO 139.
9 Procedure
9.1 Place the first test specimen flat on the white textile blotting paper (7.2) on a smooth, horizontal surfa
