Pulps. Preparation of laboratory sheets for physical testing - Conventional and Rapid-Köthen sheet formers using a closed water system Ingestion-build-48348 Pressure vessel designers and manufacturers1 Scope This part of ISO 5269 specifies two procedures for preparing a closed water system which is in retention equilibrium, to be used for the preparation of laboratory sheets from pulps with a high fines content. One procedure is applicable to the preparation of laboratory sheets using the conventional sheet former and the other using the Rapid Kthen sheet former. The sheets prepared prior to attaining retention equilibrium are discarded. This part
