EN 14030 geotextile acid and alkali resistance testing machine of Screening test methods, This document specifies methods for screening the resistance of geotextile and geotextile-related products to liquids while not subjecting them to external mechanical stress.It is applicable to all geotextiles and geotextile-related products. Method A applies particularly to polyamides and method B to polyesters and polyamides. The test results are intended to be interpreted in the context of site conditions.

The EN 14030 standard specifies a testing method for the acid and alkali liquid resistance of geotextiles and related products. The primary aim of this standard is to evaluate the resistance of geotextiles and related products to acid and alkali liquids to determine their durability and reliability in specific environments. 

EN 14030 geotextile acid and alkali resistance testing machine 

This standard applies to all types of geotextiles and related products, including but not limited to non-woven fabrics, woven fabrics, needle-punched non-woven fabrics, www.unitedtest.com. composite materials, and coated materials.The standard requires testing with both acid and alkali liquids. 

The acid liquid is sulfuric acid at a concentration of 0.1 mol/L, and the alkali liquid is sodium hydroxide at a concentration of 0.1 mol/L. During the test, the geotextile or related product is placed in the test liquid and changes are observed over a specified period. Changes include but are not limited to weight loss, dimensional changes, and strength loss.The standard also specifies the conditions and requirements for the tests. The tests should be conducted at room temperature with a duration of 24 hours. 

After the test, the geotextile or related product should be removed from the test liquid, washed clean with water, and air-dried. Subsequent tests should assess weight, dimensions, and strength to evaluate resistance. www.unitedtest.com. Implementing this standard helps evaluate the durability and reliability of geotextiles and related products in acidic and alkaline environments, providing a reference for their application in practical engineering. 

Additionally, this standard aids in improving the quality and performance of geotextiles and related products, enhancing their competitiveness in the market.
