This document This document is applicable to In many organizations, the various responsibilities of technical management are assigned to more than one person. Where the term "technical manager" or "systems engineering manager" is used in this document, the guidance, advice or normative requirement applies to the applicable role within the project or organization. This document is intended to provide guidance for two-party situations and can be equally applied where the two parties are from the same organization. This document can also be used by a single party as self-imposed tasks. This document can also serve as guidance in multi-party situations, where high risks are inherent in the supply and integration of complex systems, and procurement can involve several suppliers, organizations or parties.

This document describes fuelling protocols for liquid hydrogen (LH2), defining the minimum design, installation and operation requirements for a safe, as well as fast, efficient and interoperable hydrogen transfer from the fuelling station to the vehicle fuel system. This document applies to land vehicles of all types equipped with a liquid hydrogen storage system fulfilling ISO 13985 requirements. The protocols described in this document are currently limited to vehicles with storage system total internal volume equal to or comprised between 0,6 m3 and 4 m3. Further hydrogen applications may apply the requirements of this standard. However, further specific requirements that can be necessary for the safe operation of such fuelling are not addressed in this document. This document specifies the requirements for liquid hydrogen fuelling and dispensing systems, fuelling station - vehicle interface and vehicle storage system in order to minimise the risk of fire, explosion or any other hydrogen adverse effects to an acceptable level, especially during and after the fuelling process.

This document is not applicable to push-fit jointed discrete pipes assembled as part of the trenchless installation process.

 

This document specifies a method for the enumeration of intestinal enterococci in water. The method is based on the growth of target organisms in a liquid medium and calculation of the “Most Probable Number” (MPN) of microorganisms by reference to MPN tables or using informatic programs. The test described in this document relies upon the detection of intestinal enterococci based upon expression of the enzyme ß-D-glucosidase. This method provides a confirmed result in 24 h with no requirement for confirmation of positive wells. This method can be applied to a range of types of water (for example, drinking water, bathing water, groundwater, surface water and wastewater), including those containing an appreciable amount of suspended matter and high background counts of heterotrophic bacteria. For marine waters, enterococci are best enumerated using diluted samples.

 

This document specifies a method for the enumeration of intestinal enterococci in water, including Enterococcus faecalis, Enterococcus faecium, Enterococcus durans, Enterococcus avium, Enterococcus gallinarum, Enterococcus hirae, Enterococcus casselifavus. The method is based on the growth of target organisms in a liquid medium and calculation of the “most probable number” (MPN) of microorganisms by reference to MPN tables or using suitable MPN informatic programs. This method can be applied to drinking water and bathing water (fresh or marine), together with other similar water types including those containing an appreciable amount of suspended matter, and allows the detection of enterococci at 1 colony-forming unit (CFU) per 100 ml with definitive results within (26 ± 2) h in the presence of heterotrophic bacteria in numbers as high as 1 × 106 per 100 ml of sample. For bathing waters, fresh and marine, enterococci are best enumerated when samples are diluted 1:10. The test specified in this document relies upon the detection of intestinal enterococci based upon expression of the enzyme ß-D-glucosidase and provides a confirmed result in 24 h without further testing of positive wells. This document does not apply to bottled waters, for which the method has not been validated and therefore is outside the scope of this document, unless appropriate validation of performance of this method has been undertaken by the laboratory prior to use.

 

ISO 2507 specifies a general method for determining the Vicat softening temperature (VST) of thermoplastics pipes and fittings. It includes the adaption of method B 50 of ISO 306: 2022 using a force of 50 N and a heating rate of 50 °C/h. It includes the particular test conditions for determining the Vicat softening temperature (VST) of unplasticized poly(vinylchloride) (PVC-U) or chlorinated poly(vinylchloride) (PVC-C) pipes and fittings, for high impact resistance poly(vinylchloride) (PVC-HI) pipes and for acrylonitrile/butadiene/styrene (ABS) and acrylonitrile/styrene/acrylic ester (ASA) pipes and fittings. It also gives, for information, the corresponding base specifications. It is not applicable to crystalline or semi-crystalline polymers.

This standard is designed for the simultaneous analysis of multi-class pesticide residues in soil using GC-MS/MS and LC-MS/MS analysis following extraction with acetonitrile and buffering salts mixture, and cleanup via dispersive solid-phase extraction (d-SPE). The standard includes 30 target analytes listed in Table 1. This document can be applicable to other pesticide residues if their validity is confirmed. Under the specified conditions in this document, a limit of quantitation (LOQ) less than 0,1 mg/kg (expressed as dry matter basis) can be achieved for the target analytes (refer to Annex C).

 

This document supports the interest of system users in having consistent, complete, accurate, and usable information. It addresses both available approaches to standardization: a) process standards, which specify the way that information products are to be acquired and supplied; and b) information product standards, which specify the characteristics and functional requirements of the information. As defined in ISO/IEC/IEEE 12207 and ISO/IEC/IEEE 15288, the acquisition and supply activities make up the agreement processes of the software or system life cycle. Acquisition and supply of information for users and related services are specializations of those processes. Such services can be acquired and supplied for any part of the information management process, such as the following: This document provides an overview of the information management processes that are relevant to the acquisition and supply of information for users. It applies the Agreement processes (acquisition and supply) to information for users, and addresses the preparation of requirements for this information. These requirements are central to the information for users specification and statement of work discussed in this document. This document also addresses requirements for primary information outputs of the acquisition and supply process: the request for proposal and the proposal for information products and services. This document is intended for use in acquiring or supplying any type of information for users and is independent of information development or management tools or methodologies. This document can be helpful for acquiring and supplying the following types of information, although it does not cover all aspects of them: This document is applicable to acquirers and suppliers of information for users, including a variety of specialists: It can also be consulted by those with other roles and interests in the information development process:
