What is ISO 1833-1 about?
ISO 1833 discusses the quantitative chemical analysis of textiles. ISO 1833-1 is the first part of the multi-series ISO 1833 and discusses general principles of testing. ISO 1833-1 specifies a common method for the quantitative chemical analysis of various mixtures of fibres.
This method in ISO 1833-1 and the methods described in the other parts of ISO 1833 are applicable, in general, to fibres in any textile form. Where certain textile forms are excepted, these are listed in the scope of the appropriate part.
Who is ISO 18331 for?
ISO 18331 on quantitative chemical analysis of textile is useful for:
- Textile manufacturers
- Quality control personnel
- Testing laboratories
Why should you use ISO 1833-1?
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. ISO 1833-1 provides a procedure for determining the dry mass of test specimens and residues.
Quantitative chemical analysis is beneficial for ensuring the chemical's safety, quality, productivity, control, consistency, among other factors that affect everyday life. ISO 1833-1 helps you to manufacture better quality, safe, and durable products. ISO 1833-1 also helps you to gain consumer confidence.
What is changed since the last update?
BS EN ISO 1833-1:2020 supersedes ISO 18331:2006. BS EN ISO 1833-1:2020 includes some technical changes with respect to ISO 18331:2006. These include:
- Introduction and bibliography: a reference to ISO/TR 11827regarding the fibre identification has been added
- Normative references, Principle, Apparatus stoppered weighing bottles, instructions for handling, instructions for short drying period, a requirement regarding the number of test specimens, requirement regarding the number of test specimens have been added
- Warning sentences and reference to grade 3 water, the requirement for reporting if any pre-treatments are carried out, additional cases regarding elastane, elastolefin, bast fibres have been introduced
- Weighing note has been removed
- Additional instructions in case of calculated percentage greater than 100 % have been given
