This document provides requirements and recommendations for measuring and reporting ambient sound in water, as characterized by sound pressure and selected quantities that can be derived from sound pressure. “Ambient sound” implies sound from any source except sources of self-noise. The scope includes equipment performance, calibration and deployment, digital data acquisition and data processing…

This document specifies general requirements and guidance for metagenomics-dedicated sample preparation, and generating and analysing metagenomics sequence data obtained from massive parallel sequencing platforms. The specified metagenomics process includes the following stages: a)       sampling strategy and process, including type, storage, transportation, extraction, quality; b)       nucleic…

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.

Le présent document établit des principes pour la détermination des performances acoustiques des ventilateurs. De plus, le présent document peut être utilisé 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…

This document provides the criteria for stable on-orbit operation of the spacecraft's AOCS. It addresses the factors affecting the spacecraft's on-orbit stability by specifying principles and requirements for establishing the spacecraft AOCS's capability for stable on-orbit operation, which include: —     principles for judging data validity and the requisite procedures for…

This document specifies the minimum requirements and test methods for Platycodongrandiflorus root. It is applicable to Platycodon grandiflorus roots that are sold and used as natural medicines in international trade, including Chinese material medica (whole medicinal material) and decoction pieces derived from this plant.

This document establishes principles for the determination of the acoustic performance of fans. In addition, this document can be used to determine the acoustic performance of fans combined with an ancillary device such as a roof cowl or damper or, where the fan is fitted with a silencer, the sound power resulting from the fan and silencer combination.
