This document provides practical data collection of promoting the germination of typical vegetable seeds by applying ultrafine bubbles (UFBs) within the effective number concentrations for barley seeds specified in ISO 23016-2, ISO/TR 23016-3 and ISO 23016-4. While the application of UFB to barley seeds is systematically standardized, reports on UFB application to vegetable seeds germination are…

This document specifies a laboratory test method for evaluating the substrate (crack) movement response of water-leakage crack repair materials through permeability testing. This document outlines general principles and procedures for the test method. Specific variables that control the quantifiable parameters of the testing are filled in using relevant national standards or testing parameters,…

This document deals with the likely degradation of air performance of fans tested in standardized airways according to ISO 5801 when compared with the performance of fans tested under actual site conditions. It deals with the performance of a number of generic types of fan and fittings. The results given are intended as guidelines and only provide trends, as the system effect depends on the exact…

Le présent document traite de la dégradation probable de la performance aéraulique des ventilateurs soumis à essai sur circuits standards conformément à l’ISO 5801 par rapport aux performances de ventilateurs soumis à essai dans des conditions réelles sur site. Il traite des performances d’un certain nombre de ventilateurs et de composants génériques. Les résultats obtenus constituent des lignes…
