This document specifies a gas chromatographic method for ethanol, in which higher alcohols (propan-1-ol, butan-1-ol, butan-2-ol, 2-methylpropan-1-ol (iso-butanol), 2-methylbutan-1-ol, and 3-methylbutan-1-ol) from (0,1 up to 2,5) mass percentage, methanol from (0,1 up to 3) mass percentage and other impurities, in the range from (0,1 up to 2) mass percentage are determined. Impurities are all the compounds not attributed to the groups of higher alcohols or methanol. NOTE 1 The European ethanol blending component specification [1] sets a limit for the combined result of ethanol + higher alcohols, not the ethanol content itself. The method is developed for non-denatured ethanol samples. With sufficient attention to correct separation of the higher alcohols and other components, determination of hydrocarbons in ethanol that contains denaturants as per EN 15376[1] is possible. Water, if present in the sample, is not included in this analysis, because a signal for water is not visible in the chromatogram. Therefore, if "alcohol content" is called up in a specification, water needs to be considered separately in the calculations. NOTE 2 For the purposes of this document, the term “% (m/m)” is used to represent the mass percentage or mass fraction (?).

This International Standard defines terms related to quality assurance of culture media and reagents and specifies the requirements for the preparation of culture media and reagents intended for the microbiological analysis of food, animal feed, and samples from the food or feed production environment as well as all kinds of water. These requirements are applicable to all categories of culture media and reagents prepared for use in laboratories performing microbiological analyses. This document also sets criteria and describes methods for the performance testing of culture media and reagents. The document is applicable to end-users, commercial bodies, non-commercial bodies and labs preparing their own media. This covers all formats of culture media and reagents. The principles covered in this Standard, as described above, can be equally applied to the preparation, storage and performance testing of culture media and reagents (used in the intended analysis as described above) that are not captured in international Standards; this includes proprietary culture media, or other methods. The criteria for the performance of those culture media and reagents will be described within those other methods or in the manufacturers’ certificates.

 

 

This document defines the principles and specifies the requirements and guidelines for unique product identifiers, unique economic operator identifiers, and unique facility identifiers used in digital product passports. It covers the following areas: a) global uniqueness; b) persistence; c) syntax; d) semantics; e) interoperability; f) openness. This document accommodates unique product identifiers at three granularity levels of specificity: model, batch, or individual item, to support various operational needs. This document describes identification (ID) schemes that use issuing agencies, self-issuing systems, or a combination of both.

 

This document defines requirements for data carriers used in a digital product passport system. This covers: symbology characteristics, format, error correction codes, encoding methods, printing and production quality, and durability. This document also defines requirements on graphical or other indicators for easy recognition of DPP data carriers and the indication on the data carrier placement, machine readability, quality checking, links between physical product and digital representation. The following aspects are out of scope: Architecture and use cases, Secure elements and any other cryptographic security features.

 

This document defines a standard for secure and efficient data exchange protocols and data formats to be used for the digital product passport. Data exchange protocols establish the rules and procedures that systems follow when communicating and exchanging information. Data formats define the structure and presentation of that information so it can be understood and processed correctly by the involved systems. Together, protocols and formats ensure that data can be exchanged in a manner that is secure, reliable, and compatible across various platforms and sectors. This will guarantee that data is machine-readable, structured, searchable, and transferable through an open, interoperable network without vendor lock-in. a) Secure communication: this standard defines protocols that ensure secure and authenticated data exchange between systems, ensuring that data is protected against unauthorised access and that only authorised entities can access the information. b) Interoperability for data exchange: The protocols and data formats defined in this standard allow for easy integration with existing data exchange systems, ensure compatibility of protocols and formats across various sectors and supporting a wide range of applications and use cases. c) Ease of use and integration: Ensure that the identified protocols and formats can be implemented easily, especially for mobile devices, and are user-friendly in order to facilitate widespread adoption. d) Data integrity: The protocols and data formats defined in this document ensure the integrity of information linked to physical objects and electronic data throughout the entire value chain, extending to the product's or asset's end-of-life end-of-life. e) Documentation and Discoverability: The protocols and formats are available to individuals without specialised knowledge, enabling broader adoption across sectors In order to promote interoperability, reduce costs for businesses, and align with existing European regulations and initiatives, this document considers the data exchange protocols and data formats already in use in other legislations. Relevant existing standards are integrated into the development process to ensure consistency and coherence with industry practices and regulatory frameworks.

 

This document aims to standardize the specifications for the API of the Digital Product Passport (DPP) as mandated by the ESPR of the European Commission. The purpose of this API is to facilitate the searchability of DPPs, as well as to provide the necessary means for interactions throughout the lifecycle of a product's DPP.

 

The scope of this document includes: — the semantic description of a product, including its properties where relevant and the semantic aspects to represent the product lifecycle; — a common information model allowing for the implementation of data dictionary systems; — metadata models and formats to be used in exchange and representation, allowing for the integration of dictionaries; — rules on how to systematically use such metadata models when developing product group specific data models and dictionaries; — technical and organizational interoperability. This document follows the approach of standard interoperability layers and proposes the following aspects in this regard.

 

This document specifies requirements for decentralized data storage, archiving and data persistence of digital product passports. The archiving service securely stores historical passport data, preserving a comprehensive record of past information. This feature is particularly relevant for market surveillance purposes. Persistence is required to make sure that data included in the digital product passports remains available even when the economic operator creating the digital product passport is no longer active. This document also specifies requirements for the replication between economic operators and back-up operators as well as rules for data lifetime definition.

 

This document specifies the electrolytic cadmium plating of parts and fasteners in steel of tensile strength UTS = 1 450 MPa, copper, copper alloys and nickel alloys, whose temperature in service does not exceed 235 °C.

 

ISO 10399 specifies a procedure for determining whether a perceptible sensory difference or similarity exists between samples of two products. The method is a forced-choice procedure. The method is applicable whether a difference exists in a single sensory attribute or in several attributes. The method is statistically less efficient than the triangle test (described in ISO 4120) but is easier to perform by the assessors. The method is applicable even when the nature of the difference is unknown (i.e. it determines neither the size nor the direction of difference between samples, nor is there any indication of the attribute(s) responsible for the difference). The method is applicable only if the products are fairly homogeneous. The method is effective for a) determining that either a perceptible difference results (duo-trio testing for difference), or a perceptible difference does not result (duo-trio testing for similarity) when, for example, a change is made in ingredients, processing, packaging, handling or storage, and b) for selecting, training and monitoring assessors. Two forms of the method are described: - the constant-reference technique, used when one product is familiar to the assessors (e.g. a sample from regular production); - the balanced-reference technique, used when one product is not more familiar than the other.

 

This document specifies: — the tests for finished wiring, including connectors and, if necessary, terminals, terminal ends, junction boxes, circuit breakers, etc.; — the requirements for verification of aircraft electrical wiring; — continuity of circuits; — dielectric strength; — insulation resistance; — partial discharge for operating voltages above 230/400 V a.c. (see also TR 4907 ). These tests do not concern equipment installed in the aircraft (see operation of systems) and do not apply to the wiring used in instrumentation.

 

This document specifies the design, testing and marking requirements for spring loaded pressure relief valves (PRV), for use in liquefied petroleum gas (LPG) cylinders of water capacity of 0,5 l up to and including 150 l. These PRVs can be either an integral part of a cylinder valve (see EN ISO 14245 [4] and EN ISO 15995 [5]) or a separate device.

 

This document defines the generic names used to designate the different categories of man-made fibres, based on a main polymer, currently manufactured on an industrial scale for textile and other purposes, together with the distinguishing attributes that characterize them. The term “man-made fibres” has been adopted for those fibres obtained by a manufacturing process, as distinct from materials which occur naturally in fibrous form. This document gives recommendations of rules for the creation of the generic name (see Annex A). NOTE      These rules have been introduced in the sixth edition of ISO 2076, and thus, they are not applicable to the existing generic names of the previous editions.
