What is ISO 1833-18 about?
ISO 1833 discusses the quantitative chemical analysis of textile ISO 1833-18 is the 18th part of the multi-series ISO 1833 and discusses mixtures of silk with wool or other animal hair.
ISO 1833-18 specifies a method, using sulfuric acid, to determine the mass percentage of silk, after removal of non-fibrous matter, in textiles made of mixtures of silk with wool or other animal hair.
Who is ISO 1833-18 for?
ISO 1833-18 on quantitative chemical analysis of textile is useful for:
- Textile manufacturers
- Quality control personnel
- Testing laboratories
Why should you use ISO 1833-18?
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. Silk is a natural protein fibre, some forms of which can be woven into textiles. The protein fibre of silk is composed of fibroin and is produced by certain insect larvae to form cocoons. Sulfuric acids are known as vitriol oil, is a mineral acid composed of the molecular formula H2S04 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 1833-18 provides the required guidance on determining the quantitative chemical analysis in silk with wool or other animal hair through using sulfuric acids. Quantitative chemical analysis is beneficial for ensuring the chemical's safety, quality, productivity, control, consistency, among other factors that affect everyday life. ISO 1833-18 helps you to manufacture better quality, safe, and durable products. ISO 1833-18 also helps you to gain consumer confidence.
What is changed since the last update?
BS EN ISO 1833-18:2020 supersedes ISO 1833-18:2019. BS EN ISO 1833-18:2020 includes some technical changes with respect to ISO 1833-18:2019. These include:
- The title has been changed from “Mixtures of silk with other protein fibres…” to “Mixtures of silk with wool or other animal hair….”
- In scope “other protein fibres (e.g., wool or animal hair)” have been replaced by “wool or other animal hair”
