Determination of boron (III) oxide in refractory products - Determination of total boron (III) oxide in oxidic materials for ceramics, glass and glazes1 Scope This part of ISO 21078 specifies methods of determining boron(III) oxide in refractory products and raw materials, in mass fractions of 0,01 % or greater. It is applicable to the determination of total boron(III) oxide in oxidic materials for ceramics, glass and glazes. The determination of boron(III) oxide is carried out using one of the following four methods: a) alkaline titrimetry, which is applied to samples containing more than 0,5 % by

consumption

Computer monitors that provide a touch screen functionality are also included in BS EN IEC 62087‑7

Nor does it describe a quality assurance system for control of all stages of manufacture

They have two or more ports for the transmission of optical power and have two or more states in which power is routed or blocked between these ports

This part of IEC 60317 forms an element of a series of standards that deals with insulated wires used for windings in electrical equipment
