Fine bubble technology — Agricultural applications — Part 1: Test method for evaluating the growth p...
This document specifies a test method for evaluating the effect of fine bubble water on the growth promotion of hydroponically grown lettuce by estimating the incremental gain in mass of the stems and leaves over a specified growth period.
Polymeric materials, cellular flexible — Determination of stress-strain characteristics in compressi...
Covers the determination of material with a density up to 250 kg/m3. It also indicates a method for the calculation of the compression stress value of such materials. The compression stress/strain characteristic is a measure of the load-bearing properties of the material. Two formulas allow to calculate the results. Part 2 refers to high density materials. Constitutes a minor revision of the…
Paints and varnishes — Determination of pH value — Part 1: pH sensors with glass membrane
ISO 19396-1:2017 specifies a method for laboratory measurement of the pH value of polymer dispersions and coating materials using pH electrodes with a glass membrane. ISO 19396‑2 specifies a method for measuring the pH value using pH electrodes with ion-sensitive field-effect transistor (ISFET) technology.
Industrial automation systems and integration — Product data representation and exchange — Part 242:...
The existing scope of AP242 is not diminished by this NWI.
This NWI covers needed updates, enhancements and extensions to the STEP AP242 application protocol last published as 10303-242 ed2 in 2020 with a minor revision in progress in 2021.
The following updates, enhancements and extensions are proposed :
Updates for:

2. PMI updates in the…
Coal — Determination of extractable metals in dilute hydrochloric acid
ISO 1952:2008 describes the extraction from solid mineral fuels by dilute hydrochloric acid and determination of extractable sodium, potassium, calcium, iron and magnesium.
Essential oil of Melaleuca, terpinen-4-ol type (tea tree oil)
ISO 4730:2017 specifies certain characteristics of the essential oil of Melaleuca, terpinen-4-ol type (Tea Tree oil), in order to facilitate assessment of its quality.
Rough-terrain trucks — Safety requirements and verification — Part 2: Slewing trucks
ISO 10896-2:2016 specifies general safety requirements for slewing rough-terrain variable-reach trucks (hereafter known as "trucks"), consisting of a lower chassis with a slewing upper structure equipped with a telescopic lifting means (pivoted boom), on which a load handling device (e.g., carriage and fork arms) is typically fitted. Fork arms and other integrated attachments are…
Ventilateurs — Détermination des niveaux de puissance acoustique des ventilateurs dans des condition...
L'ISO 13347-1:2004 est applicable à la détermination des performances acoustiques des ventilateurs industriels et peut également être utilisée pour déterminer les performances acoustiques des ventilateurs combinés à un appareil dépendant tel qu'un capotage ou un registre ou, lorsque le ventilateur est équipé d'un silencieux, la puissance acoustique issue de la combinaison…
