Описание (английский):

Is suitable for use with most kinds of paper. However, it may not be suitable for some papers, which soaking makes extremely fragile and causes to curl excessively. The property of dimensional change after immersion in water should not be cofused with hydroexpansivity.

Abstract

Overview

ISO 5635:1978 specifies a laboratory method for measuring the . The standard defines how to soak conditioned paper strips, measure the change in length, and report results as a percentage relative to the original (conditioned) length. It is intended for use with most types of paper but is not suitable for sheets that become extremely fragile or curl excessively when soaked. is distinct from standards addressing .

Key topics and requirements

Scope: Method for measuring dimensional change after immersion in water; not to be confused with hygro‑expansivity.
Sampling and conditioning: Sample preparation per ISO 186; condition test pieces according to ISO 187 (standard atmosphere).
Test pieces: Cut five specimens per test, each 250 mm long and 15 mm or 20 mm wide. The long dimension is aligned with the direction (machine or cross) under examination.
Apparatus:
- Rigid test‑piece marker (~250 × 40 × 5 mm) with two chisel‑shaped metal pins set 200 ± 2 mm apart.
- Magnifying lens for measurement.
- Accurate graticule graduated to 0.2 mm.
Procedure:
- Make two small slits 200 mm apart using the marker.
- Soak the specimen in distilled water at the conditioning temperature until no further length change occurs (15 minutes is usually sufficient).
- Carefully place the wet specimen on a flat surface, reposition the marker, cut a second slit, and measure the new distance between slits.
- Ensure specimens are not under any load while wet (wet paper is weak and can stretch under small loads).
Expression of results:
- Change in length AL (mm) is converted to percent change: % change = 0.5 × AL (since the test length is 200 mm).
- Report the average of five results to the nearest 0.1%, along with test direction, conditioning atmosphere, soaking time and temperature, and any deviations.
Precision: No repeatability/reproducibility data provided in this edition.

Applications and who uses it

Quality control and material characterization in paper manufacturing, converting, and printing industries.
Laboratory testing for specification compliance when water exposure or dimensional stability is a concern (e.g., packaging, labels, archival papers).
R&D teams comparing formulations or coatings for dimensional stability after wetting.
Standards bodies and testing laboratories that reference ISO test methods.
