Determination of specimen breakdown Status: We have set up a number of testing laboratories to ensure we always remain within the threshold values set down in the relevant standards and fulfil our own generally much higher quality demands.
Samples are then stretched at a constant rate of extension until the specimen fails, so when it breaks. See all free Kindle reading apps. To get the free app, enter mobile phone number.
Your basket is empty. After washing and drying, the specimens are again measured and used to calculate dimensional change between the starting and finishing measurements in per cent.
We ensure that uvex products actually exceed the necessary safety criteria by conducting extensive tests on the material.
Then you can start reading Kindle books on your smartphone, tablet, or computer – no Kindle device required. This title may contain less than 24 pages of technical content. The results of the measurements are based on either the mean value of breaking elongation, both weft and warp samples, or the lowest value recorded. This post is also available in: Reliable protection for metalworkers.
The result is derived from the mean of four samples. Your email address will not be published.
A defined wool fabric is used as the abrasive agent reference abradant and is mounted on the abrasion machine. There are two methods for determining the tear force of fabric: Leave a Reply Cancel reply Your email address will not be published.

Click to learn more. Determination of specimen breakdown. Tests for colour fastness Colour fastness to rubbing. Two sets of test specimens are cut as defined in the test specifications, creating ten samples overall, of which five are taken against the warp and the other five against the weft of the material. Firstthe original length and width dimensions are measured, after which the samples are washed and dried according to the specifications.
Fibre analysis is carried out by examination under the microscope. This test measures the force that is required to propagate a cut, in other io the tear growth.

Determination of the abrasion resistance of fabrics by the Martindale method in accordance with EN ISO This testing method is used for flat-woven textiles and ascertains the abrasion rate, which is equivalent to the number of cycles or rubs the material can endure.

In both cases, ten specimens five weft and five warp are prepared for the test and cut to size as per the respective norm specifications, creating either a piece that resembles a pair of trouser legs or a trapezoid specimen. The faster, easier way to work with standards.
