Textiles - Test methods for nonwovens - Part 12: Demand absorbency (ISO 9073-12:2002)
ISO 9073-12 describes a method for the evaluation of the absorbency of fabrics when one side is in contact with a liquid and the fabric is under mechanical pressure.
This test is designed to allow comparison of absorbent materials such as nonwovens and is not intended to simulate in-use conditions of finished products.
Demand absorbency is also called demand wettability.

© ISO 2002 – All rights reserved 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. The main task of technical committees is to prepare International Standards. 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. Attention is drawn to the possibility that some of the elements of this part of ISO 9073 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 9073-12 was prepared by Technical Committee ISO/TC 38, Textiles. ISO 9073 consists of the following parts, under the general title Textiles — Test methods for nonwovens: =Part 1: Determination of mass per unit area =Part 2: Determination of thickness =Part 3: Determination of tensile strength and elongation =Part 4: Determination of tear resistance =Part 6: Absorption =Part 7: Determination of bending length =Part 8: Determination of liquid strike-through time (simulated urine) =Part 9: Determination of drape coefficient =Part 10: Generation of lint and other particles in the dry state =Part 11: Run-off =Part 12: Demand absorbency Annex A forms a normative part of this part of ISO 9073.

1 Textiles — Test methods for nonwovens — Part 12: Demand absorbency 1 Scope This part of ISO 9073 describes a method for the evaluation of the absorbency of fabrics when one side is in contact with a liquid and the fabric is under mechanical pressure. This test is designed to allow comparison of absorbent materials such as nonwovens and is not intended to simulate in-use conditions of finished products. NOTE Demand absorbency is also called demand wettability. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 9073. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 9073 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 139:1973, Textiles — Standard atmospheres for conditioning and testing ISO 3696:1987, Water for analytical laboratory use — Specification and test methods 3 Terms and definitions For the purposes of this part of ISO 9073 the following terms and definitions apply. 3.1 maximum absorbed mass Af mass of liquid absorbed, in grams, at time Tf, when the absorbed mass variation in the previous 5 s time period is lower than 1 % of the absorbed mass corresponding to Tf 3.2 demand absorbency capacity DAC maximum absorbed mass of liquid, Af, divided by the mass of the test piece, m, expressed in grams per gram 3.3 maximum absorption rate MAR maximum change in liquid absorbed mass per time interval, expressed in grams per second SIST EN ISO 9073-12:2005

© ISO 2002 – All rights reserved NOTE The MAR is calculated over a 1 s time period from data recorded with sampling intervals of 0,25 s or less. The maximum absorption rate is observed at the point of inflexion of the curve absorbed mass of liquid versus time. 4 Principle The method measures the demand absorbency of a fabric under constant mechanical pressure. The test piece is placed on a specified porous plate, which is connected by a siphon to a liquid reservoir. The level in the reservoir is set below the upper surface of the porous plate. The demand absorbency is measured in terms of the change in mass of the reservoir with time. 5 Apparatus See Figure 1. Dimensions in millimetres
