There are numerous pathways to produce hydrogen. This document specifies a methodology for different hydrogen production pathways for determining the greenhouse gases (GHG) emissions associated with the hydrogen supply chain from the raw material extraction up to the production gate.
This document considers the GHG emissions associated with hydrogen production up to the production gate. This document applies to and includes every step within the production process up to the production gate (see Figure 2 in the Introduction).
NOTE            Complementary documents in the ISO 19870 series will consider hydrogen conditioning, conversion and transport methods.
ISO 14044 requires the goal and scope of a life cycle assessment (LCA) be clearly defined and be consistent with the intended application. Due to the iterative nature of LCAs, it is possible that the LCA scope needs to be refined during the study. According to ISO 14040:2006, A.2, the goals and scope of LCAs correspond to one of the following two approaches:
an approach that assigns elementary flows and potential environmental impacts to a specific product system, typically as an account of the history of the product (see 4.1.2);
an approach that studies the environmental consequences of possible (future) changes between alternative product systems (see 4.1.3).
In this document, approach a) is referred to as an attributional approach, while approach b) is referred to as a consequential approach. Complementary information is accessible in the ILCD handbook[4].
A carbon footprint of a product (CFP) (3.1.2) or partial CFP (3.1.3) as defined by ISO 14067 can be estimated using either the attributional or the consequential approach, the latter corresponding to the use of “system expansion via substitution” to avoid allocation when a unit process yields multiple co-products. This document applies to the CFP for hydrogen production.

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, interoperable, reliable, and compatible across various platforms and sectors.
This will guarantee that data are human and machine-readable, structured, searchable, and transferable through an open, interoperable network without vendor lock-in.
a)   Secure communication:
This document defines protocols that ensure secure and authenticated data exchange between systems, ensuring that data are protected against unauthorised access and, when necessary, only authorized entities can access the information.
b)   Interoperability for data exchange:
The protocols and data formats defined in this document support 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.
e)   Documentation and discoverability:
The protocols and formats are available to individuals without specialized 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 encompasses the determination of the fatty acid profile in algae and algae products, thereby including micro- and macroalgae, according to the definitions adopted by CEN. This determination enables that all fatty acids present at a significant level (> 1 % of the total fatty acids) in the algal matrix are quantified in an accurate and reproducible way. The concentration of each fatty acid will be available in relative (in %) and, by means of an appropriate internal standard, absolute (mg/g dw) terms. Moreover, the method described in this standard ensures a practical and safe technical approach, whose protocol details and all related know-how will be easily and economically transferrable to all the sector stakeholders. This document ensures this objective by a comprehensive and fully detailed description of all technical steps from the sample itself (including its state and form) to the gas chromatographic technique and the calculation of the fatty acid content. The wording avoids any risk of ambiguity or wrong interpretation. Finally, this methodological standard will be informed by other equivalent standards applied to other matrices and will take into account other standards concerning specific treatment or extractive procedure of the sample prior to the fatty acid analysis itself.

This document 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:
determining that either:
a perceptible difference results (duo-trio testing for difference); or
a meaningful perceptible difference does not result (duo-trio testing for similarity) when, for example, a change is made in ingredients, processing, packaging, handling or storage;
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.

1.1        General
This document specifies methods for determining the sound power level of a noise source from sound pressure levels measured on a surface enveloping the noise source (machinery or equipment) in an environment that approximates to an acoustic free field near one or more reflecting planes. The sound power level produced by the noise source, in frequency bands or with A-weighting applied, is calculated using those measurements.
NOTE   Differently shaped measurement surfaces can yield differing estimates of the sound power level of a given noise source which are accounted for in the uncertainty associated with this test method. An appropriately drafted noise test code (see ISO 12001) gives detailed information on the selection of the surface.
1.2        Types of noise and noise sources
The methods specified in this document are suitable for all types of noise (steady, non-steady, and fluctuating) as defined in ISO 12001, except for short duration, impulsive events.
This document is applicable to all types and sizes of noise source (e.g. stationary or slowly moving component or sub-assembly), provided that the conditions for the measurements can be met.
NOTE   It is possible that the conditions for measurements given in this document are impracticable for very tall or very long sources such as chimneys, ducts, conveyors and multi-source industrial plants. A noise test code for the determination of noise emission of specific sources can provide alternative methods in such cases.
1.3        Test environment
The test environments that are applicable for measurements made in accordance with this document can be located indoors or outdoors, with one or more sound-reflecting planes present on or near which the noise source under test is mounted.
