This method describes the determination of the carbohydrate composition in wood pulp samples. This method makes it possible to determine concentrations of individual anhydrous monosaccharides down to 1 mg/g oven-dry pulp.
Pulps — Determination of lignin content — Acid hydrolysis method
The method is applicable to unbleached, bleached and semi-bleached wood pulp with a lignin content above 1 %. It is not generally intended for fully bleached chemical pulp, because the lignin content in these pulps is too low to be determined accurately.

Electrical insulation systems - Thermal evaluation of modifications to an established electrical ins...
IEC TR 61858-3:2020(E) provides information on the identification of electrical insulating materials and auxiliary components for the assessment of modifications to an established insulation system and gives guidance on the selection of feasible test procedures.
Lifecycle requirements for functional safety and security for IACS
IEC PAS 63325:2020 provides requirements and guidance on the ensurance and assurance of functional safety and security in different stages of the lifecycle. It will help to coordinate risk assessment, design and management and operation processes, avoiding conflicts between functional safety and security.
This PAS does not aim to give some completely new lifecycle, but based on the functional…
Measurement of the complex permittivity for low-loss dielectric substrates balanced-type circular di...
IEC 63185:2020 relates to a measurement method for complex permittivity of a dielectric substrates at microwave and millimeter-wave frequencies. This method has been developed to evaluate the dielectric properties of low-loss materials used in microwave and millimeter-wave circuits and devices. It uses higher-order modes of a balanced-type circular disk resonator and provides broadband…
