IEC 63098-3:2022 This part of IEC 63098 provides the specifications of the RoF interface connecting the central station (CS) with the remote radar heads (RRHs) in a remote radar system, along with the necessary information to ensure compatibility between vendors and, hence, choose appropriate systems to cover any type of RoF systems for delivering the signal.A remote radar system generally…

This document specifies two procedures for the preparation of laboratory sheets prior to measuring optical properties. One is the preparation of pads in a Büchner funnel using a filter paper or a wire screen and the other one is the preparation of laboratory sheets in a standard sheet former (conventional or Rapid Köthen). This document is applicable to all wood pulps and to most other types of…

Le présent document spécifie deux modes opératoires pour la préparation des feuilles de laboratoire préalablement au mesurage des propriétés optiques. L’un consiste à préparer des galettes dans un entonnoir Büchner en utilisant un papier-filtre ou une toile, l'autre à préparer des feuilles de laboratoire dans une formette standard (conventionnelle ou Rapid-Köthen). Le présent document est…
