Sludge, treated biowaste, soil and waste - Determination of dry residue or water content and calculation of the dry matter fraction on a mass basis (ISO/DIS 11465:2024)

The method specified can be applied to all types of soil samples. Different procedures are specified for air-dried soil samples, e.g. samples pretreated according to ISO 11464, and for field-moist soil samples. Its principle is drying soil samples to constant mass at 105 °C and using the difference in mass of an amount of soil before and after the drying procedure to calculate the dry matter and water contents on a mass basis. For the determination of soil water content on a volume basis, refer to ISO 11461.

This document specifies functional requirements for the design, construction, testing, commissioning/decommissioning, operation, maintenance and where appropriate calibration, together with suitable documented provisions for all new gas measuring systems and any major changes of existing systems. This document also specifies accuracy classes of measuring systems and thresholds applicable to these classes. Demonstration of compliance is achieved through the selection, installation and operation of appropriate measurement instruments, together with suitable documented provisions for calculations. Examples of demonstration of compliance are provided for each accuracy class; however, they are not prescriptive solutions. This document is applicable for gases of the 2nd gas family as classified in EN 437 and for hydrogen and its blends with gases of the 2nd gas family. This document can also be used as a guideline for 1st and 3rd family gases as classified in EN 437; however additional considerations should be taken with regard to the different constituents and physical characteristics of the gas family. This document is not applicable for: - raw or sour gases. - gas measurement in CNG and hydrogen fuelling stations. This document gives guidelines when installing and operating gas meters with additional functionalities (smart meters). Unless otherwise specified all pressures used in this document are gauge pressures. For associated pressure regulating systems the requirements of EN 12186 and/or EN 12279 apply. For requirements on design, housing, lay-out, materials for components, construction, ventilation, venting and overall safety of gas measuring systems within the scope of this document, EN 15001, EN 12186, EN 12279 and/or EN 1775 apply additionally, where relevant. This document specifies common basic principles for gas infrastructure. Users of this European Standard should be aware that more detailed national standards and/or codes of practice can exist in the CEN member countries. This European Standard is intended to be applied in association with these national standards and/or codes of practice setting out the above mentioned basic principles. In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this European Standard, national legislation/regulation takes precedence as illustrated in CEN/TR 13737 parts 1 and 2. CEN/TR 13737 (all parts) gives:  clarification of all legislation/regulations applicable in a member state;  if appropriate, more restrictive national requirements;  a national contact point for the latest information.

Soil quality - Estimation of abundance of selected microbial gene sequences by quantitative PCR from DNA directly extracted from soil (ISO/DIS 17601:2024)

ISO 17601:2016 specifies the crucial steps of a quantitative real-time polymerase chain reaction (qPCR) method to measure the abundance of selected microbial gene sequences from soil DNA extract which provides an estimation of selected microbial groups. It is noteworthy that the number of genes is not necessarily directly linked to the number of organisms that are measured. For example, the number of ribosomal operon is ranging from one copy to 20 copies in different bacterial phyla. Therefore, the number of 16S rRNA sequences quantified from soil DNA extracts does not give an exact estimate of the number of soil bacteria. Furthermore, the number of sequences is not necessarily linked to living microorganisms and can comprise sequences amplified from dead microorganisms.
