What is ISO 1833-17 about?
ISO 1833 discusses the quantitative chemical analysis of textiles. ISO 1833-17 is the 17th part of the multi-series ISO 1833 and discusses mixtures of cellulose fibres and certain fibres with chlorofibres and certain other fibres.
ISO 1833-17 specifies a method, using concentrated sulfuric acid, to determine the mass percentage of chlorofibres and certain other fibres, after removal of non-fibrous material, in textiles made of mixtures of cotton, viscose, cupro, modal, lyocell, acetate, triacetate, polyamide, polyester, elastomultiester, certain acrylic and certain modacrylic fibres with chlorofibres (based on homopolymers of vinyl chloride), polypropylene, elastolefin, melamine and polypropylene/polyamide bicomponent.
Who is ISO 1833-17 for?
ISO 1833-17 on quantitative chemical analysis of textile is useful for:
- Textile manufacturers
- Quality control personnel
- Testing laboratories
Why should you use ISO 1833-17?
Quantitative analysis is any method used for determining the amount of a chemical in a sample. The amount is always expressed as a number with appropriate units. An acid-base titration is an example of quantitative analysis. Sulfuric acid is also known as vitriol oil, is a mineral acid composed of the molecular formula H2SO4 with sulphur, oxygen, and hydrogen components. It is a colourless, odourless, and smooth liquid that is soluble in water and synthesized in a highly external reaction.
ISO 1833-17 provides the required guidance on determining the quantitative chemical analysis in textile by using concentrated sulfuric acid it also included the principles, reagents, apparatus, and test procedures.
Quantitative chemical analysis is beneficial for ensuring the chemical's safety, quality, productivity, control, consistency, among other factors that affect everyday life. ISO 1833-17 helps you to manufacture better quality, safe, and durable products. ISO 1833-17 also helps you to gain consumer confidence.
What is changed since the last update?
BS EN ISO 1833-17:2020 supersedes ISO 1833-17:2006. BS EN ISO 1833-17:2020 includes some technical changes concerning ISO 1833-17:2006. These include:
- The title has been changed from “Mixtures of chlorofibres (homopolymers of vinyl chloride) and certain other fibres (method using sulfuric acid)” to “Mixtures of cellulose fibres and certain fibres with chlorofibres and certain other fibres (method using concentrated sulfuric acid)”
- Scope has been rearranged and several remaining fibres have been added
- Principle has been rearranged according to the scope
- Dilute solution has been added
- A specific d factor for melamine and propylene/polyamide bicomponent has been added
