ISO9863 ASTM D5199 Geotextile Thickness Tester

Resistance to stress cracking using notched constant tensile load test BS EN ; ASTM D This test consists of subjecting a dumbbell shaped notched specimen to a constant tensile load in the presence of a surface-active agent at an elevated temperature.


Astj method for nominal thickness of geotextile View our schedule of UKAS accredited tests.

Presser Foot “A” Dim. It is the responsibility of aastm user of d5919 standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The specimen is then held at constant temperature until the oxidative reaction is displayed on the thermal curve. This test measures the rate of extrusion of molten polymer through a die of specified length and diameter at specified conditions ast temperature, load, and piston position in the barrel as a timed measurement is made.

After the full force has been applied to presser foot for 5 s against the specimen, record the thickness value to the nearest 0. No orders will ship and email response will be delayed during this time. Refer to details below. Exclude the inner and outer wraps of the roll or any material containing folds, crushed areas or other distortions not representative of the sampled lot.

ASTM D – 12 – Standard Test Method for Measuring the Nominal Thickness of Geosynthetics

Four different materials were tested. This test method determines nominal thickness, not necessarily minimum thickness. The appearance is compared to a dispersion reference chart.

Care should be exercised to minimize these effects. A time of at least 24 h has been found acceptable accept able in most cases. For geomembranes include at least one specimen taken 5d199 more than mm 6 in.


The laboratory asstm contains three separately conditioned laboratories and a large preparation area with a loading bay to handle samples directly from site and from manufacturers.

Thickness is one of the basic physical properties used to control the quality of many geosynthetics. Custom Sized presser feet and weights mass to fit specific needs or applications are also available.

Note 1—The user should be aware that the compressibility of some materials, their rebound characteristics, and other phenomenon will affect the thickness of some geosynthetics, following the time when they are rolled up, shipped and stored.

It is then immersed in liquid, its loss in weight upon immersion is determined and its density calculated. This test consists of subjecting a dumbbell shaped notched specimen to a constant tensile load in the presence of a surface-active agent at an elevated temperature.
