Information technology - Generic cabling for customer premises
Within customer premises, the importance of the cabling infrastructure is similar to that of other fundamental building utilities such as heating, lighting and mains power. As with other utilities, interruptions to service can have a serious impact. Poor quality of service due to lack of design foresight, use of inappropriate components, incorrect installation, poor administration or inadequate…

Plastics — Epoxy resins — Determination of chlorine content — Part 1: Inorganic chlorine
ISO 21627 specifies a direct potentiometric method for the determination of inorganic chlorine in epoxy resins, also called ionic chlorine.
The inorganic chlorine content is expressed in milligrams per kilogram of epoxy resin.
Plastics — Epoxy resins — Determination of chlorine content — Part 2: Easily saponifiable chlorine
ISO 21627-2 specifies a method for the determination of easily saponifiable chlorine in epoxy resins.
The values obtained are indicative of the concentration of easily saponifiable chlorine of chlorohydrin groups in the compounds.
The easily saponifiable chlorine content is the quantity of easily saponifiable chlorine in a given quantity of epoxy resin.
Plastics — Epoxy resins — Determination of chlorine content — Part 3: Total chlorine
ISO 21627-3 specifies a method for the determination of the total chlorine contained in epoxy resins.
The amount of chlorine measured by this method, referred to as total chlorine, includes saponifiable organic chlorine and inorganic chlorine.
