SFS esittää tätä standardia vahvistettavaksi SFS-ISO-standardiksi. Keräämme tällä lausunnolla kannanottoja standardiluonnoksen vahvistamiseksi kansalliseksi SFS-ISO-standardiksi. Jätä kommenttisi tätä koskien kohdassa ’Lue ehdotus’ — tulisiko tämä ISO-standardiluonnos vahvistaa kansalliseksi SFS-ISO-standardiksi*.
 
*SFS:n tehtävänä on ylläpitää suomalaista SFS-standardikokoelmaa. Maailmanlaajuisten standardien kohdalla ISO vahvistaa standardin ensin, ja Suomi päättää sen jälkeen, vahvistaako se standardin vai ei. Vahvistamispäätökseen vaikuttaa alan suomalainen näkemys ja kiinnostus vahvistettavaan standardiin.

 

This International Standard specifies a gas-Liquid chromatography (GLC) method for the determination of the mean relative molecular mass of technical straight-chain sodium alkylbenzenesulfonates.

 

This document specifies a test method for the simultaneous determination of primary aromatic amines (PAAs) in organic pigments using external reference standards. The separation, identification and quantification of PAAs are achieved by high-performance liquid chromatography (HPLC) analysis with gradient elution and diode array detection (DAD) and/or mass spectrometry detection (MSD) after an extraction step. This analytical procedure can be applied to all organic pigments. The method allows the determination of extractable PAA content including sulfonated PAAs.

This document specifies a method for the enumeration of culturable microorganisms in water by counting colonies on a low-nutrient agar culture medium by spread plate inoculation after incubation at 22 °C for 7 days. This document is applicable to: — water from the treatment process of public drinking water supplies (e.g. process water in the waterworks); — chlorinated and non-chlorinated tap water in distribution systems and containers; — bottled water; — well water intended for human consumption.

A device which implements this capability is called a PXD. This document is applicable to PICCs of Type A and of Type B (as described in ISO/IEC 14443-2), to PCDs (as described in ISO/IEC 14443-2) and to PXDs.

 

This document specifies a method for the enumeration of culturable microorganisms in water by counting the colonies on a low-nutrient agar culture medium after incubation at 22 °C for 7 d. The method is intended to measure the operational efficiency of the treatment process of public drinking water supplies, including the water in distribution systems and containers. The method is particularly suitable to monitor water for human consumption which is low in nutrients and is distributed in temperatures below 20 °C. The method can be applied to all types of water, including pool and spa waters. NOTE 1 The low-nutrient agar in use in this document usually gives higher colony counts from water samples than nutrient-rich formulations of culture media typically used for enumeration of culturable microorganisms. NOTE 2 The method is also applicable for waters of very low nutrient content such as de-ionised, distilled or reverse osmosis waters. NOTE 3 This document describes the use of R2A medium. There are other formulations available, e.g. R3A medium that might be suitable for certain applications but go beyond the scope of this document.

NOTE When accuracy is proven, real-time analysis can be supplemented by further fuel-characterising parameters. This document applies to solid recovered fuels according to ISO 21640.

To determine liquid flow, the following steps are necessary: 1) Measure water surface velocity with techniques using radar, laser or video images; 2) Correct the water surface velocity due to wind effects if necessary; 3) Option a: Transform the corrected velocity to a depth-averaged velocity in one segment using the arithmetic methods referring to chapter 7.2, secondly calculate each segment and then create the sum of all segments to obtain the cross-sectional averaged velocity distribution; 3) Option b: Transform the corrected velocity to a cross sectional velocity using the index methods referring to chapter 7.3; 4) Determine the area of the wetted cross section from the stage-area relationship; 5) Obtain discharge of each segment by multiplying the depth-averaged velocity in each segment by the wetted cross-sectional area of each segment. And then create the sum of all segments to obtain whole discharge in cross section. This procedure is applicable to different kinds of channel and river sections. Applications include: — Rivers and streams; — Artificial channels such as drainage ditches and irrigation channels; — Process flows on wastewater treatment plants. For any individual site the method to measure water surface velocity should be selected appropriately, based on the site conditions, nature of the application and uncertainty required. Take a special note that non-contact methods should not be used where a unique relation between surface velocity and depth averaged velocity cannot be established, e.g. where tidal phenomena are present. This is caused by the variations of flow magnitude and direction over depth being highly variable over time under these circumstances. Regarding backwater zones or in the vicinity of obstacles the relation between surface velocity and depth averaged velocity may be more complicated, but even here optical methods may be helpful to at least learn the situation at the surface.

 

Scope of the proposed deliverable To determine liquid flow, the following steps are necessary: 1) Measure water surface (or near surface) velocity with techniques using radar, laser or video images; 2) Adjust wind effects to the water surface velocity; 3) Translate the adjusted velocity to an averaged velocity by applying the velocity index or numerical computation; 4) Determine the area of the wetted cross section from the stage area relationship; and 5) Obtain water discharge by multiplying the averaged velocity by the wetted cross sectional area. This procedure is applicable to different kinds of channel and river section. Applications include: •Rivers and streams; •Artificial channels such as drainage ditches and irrigation channels; •Wastewater flows discharging to sewer or the environment through channels or partially filled pipes; •In sewer measurements; •Process flows on wastewater treatment plants. For any individual site the method to measure water surface velocity should be selected appropriately, based on the site conditions, nature of the application and uncertainty required. Take a special note that non-contact methods should NOT be used where a tidal phenomenon is present.
