Plastics — Polyether polyols and polymer polyols — Determination of aldehydes and ketones

This document specifies the determination of aldehydes and ketones content in polyether polyols and polymer polyols by high performance liquid chromatography (HPLC). This document is applicable to the determination of formaldehyde (HCHO), acetaldehyde (CH3CHO), acrolein (CH2=CHCHO) and acetone (CH3COCH3) in polyether polyols and polymer polyols.

Plastics — Aromatic isocyanates for use in the production of polyurethanes — Determination of total chlorine

This document specifies the determination of the total chlorine content of aromatic isocyanates used in the preparation of polyurethanes. The difference between the total chlorine content and the hydrolyzable chlorine content (see ISO 15028) is a measure of the process solvents left in the product. All the test methods are applicable to a variety of organic compounds, including aliphatic isocyanates, but the amount of sample used might need to be adjusted. These test methods can be used for research or for quality control.

Plastics — Polyols for use in the production of polyurethanes — Determination of degree of unsaturation by using iodine method

This document specifies a method for quantifying the total unsaturation using an addition reaction of the interhalogen compound iodine monochloride (ICl), using glacial acetic acid as a solvent as a method for measuring the total unsaturation of a polyether polyol for polyurethanes. It is not applicable to unsaturated compounds that are conjugated with a carbonyl group, a carboxyl group, or a nitrile group.

Frequently Asked Questions

ISO/TC 61/SC 12/WG 6 is a Subcommittee within the International Organization for Standardization (ISO). It is named "Polyurethane raw materials". This committee has published 6 standards.

ISO/TC 61/SC 12/WG 6 develops ISO standards. Currently, there are 6 published standards from this subcommittee.

The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.

A Subcommittee (SC) in ISO operates under a Technical Committee and focuses on a specific subset of the TC's scope. Subcommittees develop standards and technical specifications in their specialized area, reporting to their parent Technical Committee. They may also have working groups for detailed technical work.
