This International Standard specifies the method for quantitative and qualitative analysis of extractable alkylphenols (AP) without derivatization step in textile and textile-related products.

This standard requires the use of GC-MS/MS (Gas chromatograph with tandem mass spectrometer), LC/MS/MS (Liquid chromatograph with tandem mass spectrometer) or LC/FLD (Liquid chromatograph with fluorescence detector)

This part of ISO 18254 specifies the NPLC (Normal Phase Liquid Chromatography) separation method for the qualitative and quantitative analysis of extractable alkylphenol ethoxylates (APEO) in textile products.

This method provides several instrument options for the determination of alkylphenol ethoxylates (APEO) such as NP-LC/MS (Normal Phase Liquid Chromatograph with Mass Spectrometer), NP-LC/FLD (Normal Phase Liquid Chromatograph with Fluorescence Detector), NP-LC/CAD (Normal Phase Liquid Chromatograph with Charged Aerosol Detector) and NP-LC/ELSD (Normal Phase Liquid Chromatograph with Evaporative Light Scattering Detector).

This International Standard specifies the information accompanying geosynthetics to enable the user on site to identify the goods as being identical to the goods ordered. The positive identification, e.g. of unwrapped or rolled-out geosynthetics, is an important aim of this standard.

The information specified does not replace that on a technical data sheet, and cannot be used to verify the compliance of the product with the technical requirements.

This standard specifies a method for the on-site installation, retrieval and testing of geosynthetic samples, irrespective of the particular degradation mechanisms to which they are exposed.

The method is also appropriate to test for mechanical damage, much of which occurs during installation, and to provide an owner with information about the state of the geotextile or geotextile-related product in his structure.

NOTE          the durability of geosynthetics is assessed by short-term accelerated under conditions more extreme than those experienced in service. In order to establish the validity of these it is essential to compare their predictions with these made on material extracted from site.

This part of ISO 1833 specifies a method, using sulfuric acid, to determine the mass percentage of silk, after removal of non-fibrous matter, in textiles made of binary mixtures of

with other protein fibres (e.g. wool or animal hair).

This International Standard describes an index test procedure for simulating mechanical damage to geosynthetics, caused by granular material, under repeated loading. The damage is assessed visually and by the loss of tensile strength.

Other reference tests may be used to assess the damage caused by this test. The test method described is an index test procedure, using a standard granular material, and should not be used for the derivation of a reduction factor for geosynthetic soil reinforcement.
