Information technology — Cloud computing — Interoperability and portability

Information technology — Cloud computing — Interoperability and portability

ISO/IEC 19941:2017 specifies cloud computing interoperability and portability types, the relationship and interactions between these two cross-cutting aspects of cloud computing and common terminology and concepts used to discuss interoperability and portability, particularly relating to cloud services. ISO/IEC 19941:2017 is related to other standards, namely, ISO/IEC 17788, ISO/IEC 17789, ISO/IEC 19086‑1, ISO/IEC 19944, and in particular, references the cross-cutting aspects and components identified in ISO/IEC 17788 and ISO/IEC 17789 respectively. The goal of this document is to ensure that all parties involved in cloud computing, particularly CSCs, CSPs and cloud service partners (CSNs) acting as cloud service developers, have a common understanding of interoperability and portability for their specific needs. This common understanding helps to achieve interoperability and portability in cloud computing by establishing common terminology and concepts.

Capability of detection — Part 7: Methodology based on stochastic properties of instrumental noise

This document specifies the practical use of the fundamental concepts in ISO 11843 in case of the background noise predominance in instrumental analysis. This document specifies basic methods to — extract the stochastic properties of the background noise, — use the stochastic properties to estimate the SD or CV of the response variable, and — calculate the minimum detectable value based on the SD or CV obtained above. The methods described in this document are useful for checking the detection of a certain substance by various types of measurement equipment in which the background noise of the instrumental output predominates over the other sources of measurement uncertainty. Feasible choices are visible and ultraviolet absorption spectrometry, atomic absorption spectrometry, atomic fluorescence spectrometry, luminescence spectrometry, liquid chromatography and gas chromatography.

Horizontal methods for molecular biomarker analysis — Methods of analysis for the detection of genetically modified organisms and derived products — Part 9: Construct-specific real-time PCR based screening method for the detection of the P35S-nptII DNA-sequence

This document specifies a procedure for the detection of the DNA transition sequence between the 35S promoter region from cauliflower mosaic virus (P35S) and the neomycin-phosphotransferase gene (nptII) from the Tn5 transposon of Escherichia coli. The P35S-nptII segment is part of a construct which confers resistance to neomycin/kanamycin antibiotics frequently found in genetically modified (GM) plants. The detection method is based on real-time PCR and can be used for qualitative screening purposes. For identification and quantification of a specific GM plant (event) a follow-up analysis has to be carried out. This method is applicable for the analysis of DNA extracted from foodstuffs. It can also be suitable for the analysis of DNA extracted from other products such as feedstuffs and seeds. The application of this method requires the extraction of an adequate amount of amplifiable DNA from the relevant matrix.

Horizontal methods for molecular biomarker analysis — Methods of analysis for the detection of genetically modified organisms and derived products — Part 8: DNA extraction from alfalfa seeds and real-time PCR based detection methods for genetically modified alfalfa events J101, J163 and KK179

This document specifies procedures for DNA extraction from alfalfa (Medicago sativa) seeds and for the specific detection of the herbicide-tolerant alfalfa events J101 and J163 and the lignin-modified alfalfa event KK179 in crop/plant/seed/grain test samples. The detection methods are based on real-time PCR and are targeting the DNA transition sequences between the alfalfa genome and the respective integrated gene construct. The methods can be applied for direct event-specific identification or as a follow-up analysis, if sequences encoding the promoter of the Figwort mosaic virus (P-FMV), the terminator of the nopaline synthase gene from Rhizobium radiobacter (T-nos), or the construct CTP2/CP4-EPSPS (herbicide tolerance) were detected by screening analyses of test samples. In this document, the methods were validated using ground alfalfa seeds and DNA extracted thereof. The PCR methods are also applicable for the analysis of other matrices such as feed and foodstuffs. The application of these PCR methods requires the extraction of an adequate amount of amplifiable DNA from the relevant matrix.

Sterilization of health care products — Radiation — Part 1: Requirements for the development, validation and routine control of a sterilization process for medical devices

1.1 This document specifies requirements for the development, validation and routine control of a radiation sterilization process for medical devices. NOTE Although the scope is limited to medical devices, this document can be applicable to other products and equipment. This document covers radiation processes employing irradiators using: a) the radionuclide 60Co or 137Cs; b) a beam from an electron generator; or c) a beam from an X-ray generator. 1.2 This document is not applicable to processes for inactivating viruses or the causative agents of spongiform encephalopathies, such as scrapie, bovine spongiform encephalopathy and Creutzfeldt-Jakob disease. NOTE For information on such processes, see ISO 22442-1, ISO 22442-2, ISO 22442-3, ISO 13022 and ICH Q5A. 1.2.1 This document does not specify requirements for designating a medical device as sterile. NOTE Regional and national requirements can designate medical devices as sterile. See, for example, EN 556-1 or ANSI/AAMI ST67. 1.2.2 This document does not specify a quality management system for the control of all stages of production of medical devices. NOTE It is not a requirement of this document to have a complete quality management system during manufacture, but the elements of a quality management system that are the minimum necessary to control the sterilization process are normatively referenced at appropriate places in the text (see, in particular, REF Section_sec_4 \r \h Clause 4 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000E000000530065006300740069006F006E005F007300650063005F0034000000 ). Attention is drawn to the standards for quality management systems (see ISO 13485) that control all stages of production of medical devices, including the sterilization process. Regional and national regulations for the provision of medical devices can require implementation of a complete quality management system and the assessment of that system by a third party. 1.2.3 This document does not require that biological indicators be used for validation or monitoring of radiation sterilization, nor does it require that a pharmacopoeial test for sterility be carried out for product release. 1.2.4 This document does not specify requirements for occupational safety associated with the design and operation of irradiation facilities. NOTE Regulations on safety requirements for occupational safety related to radiation can exist in some countries. 1.2.5 This document does not specify requirements for the sterilization of used or reprocessed devices.
