DD ENV 1897:1996 - Geotextiles and geotextiles related products. Determination of the compressive creep properties
Printed version of this is available at library. To request, please e-mail to referencepk@usm.my and include a copy of this record in your e-mail.
This Standard describes methods for determining the compressive creep behaviour
of geotextiles and geotextile-related products by measurement of the rate of change of thickness with respect to time.
The test specimens can be subjected either to normal compressive loading or to a
combination of normal compressive loading and shear loading, Products which are
to be used for carrying water in the plane of the product and which are to be
subsequently tested for this function, are tested according to the procedure using
a combination of normal and shear loading (see clause 6).
The tests are carried out with the specimen immersed in water, unless it can be
shown that carrying out the tests in the dry does not affect the results.
