Plastics — Polyols for use in the production of polyurethanes — Determination of basicity (total ami...
The method specified in ISO 25761:2014 measures the basic constituents in polyols that are soluble in glacial acetic acid and reactive with perchloric acid. Samples containing 0,3 % to 10 % of nitrogen have been evaluated by this method. The method is applicable to amine-based polyols, polyether polyols and polyether polyol blends that are used in polyurethane reactions. The results are measures…

Information technology — Environmental Data Coding Specification (EDCS)
ISO/IEC 18025:2014 provides mechanisms to specify unambiguously objects used to model environmental concepts. To accomplish this, a collection of nine EDCS dictionaries of environmental concepts are specified:
classifications: specify the type of environmental objects;
attributes: specify the state of environmental objects;
attribute value characteristics: specify information concerning the…
