This document provides product category rules (PCR) guidance for the development of environmental declarations for masonry units according to EN 15804:2012+A2:2019. This document defines the parameters to be reported, the EPD types (and life cycle stages) to be covered, the rules to be followed in order to generate life cycle inventories (LCI) and conduct life cycle impact assessments (LCIA), and the data quality to be used in the development of EPDs. This document is also applicable to clay construction products manufactured with the same materials and using the same processes as clay masonry units, In addition to the common parts of EN 15804:2012+A2:2019, this document: — defines the system boundaries; — defines the modelling and assessment of material-specific characteristics; — defines allocation procedures for multi-output processes along the production chain; — defines allocation procedures for reuse and recycling; — includes the rules for calculating the LCI and the LCIA underlying the EPD; — provides guidance/specific rules for the determination of the reference service life (RSL); — gives guidance on the establishment of default scenarios; and — gives guidance on default functional units for masonry products. This document is intended to be used for cradle to gate, cradle to gate with options or cradle to grave assessments, when the intention is clearly stated in the system boundary description.

Maisto produktai. Visuminio azoto kiekio nustatymas pagal Diuma (Dumas) principą ir žalių baltymų kiekio skaičiavimas. 2 dalis. Varpiniai bei ankštiniai javai ir varpinių javų produktai (ISO/DIS 16634-2:2025)

ISO 16634-2:2016 specifies a method for the determination of the total nitrogen content and the calculation of the crude protein content of cereals, pulses and milled cereal products. This method, like the Kjeldahl method (see References [1] and [6]), does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of the protein content, various conversion factors are used (see 3.2).

This document specifies a method for extraction, separation, and determination of inorganic arsenic (iAs) in growing media and soil improvers using anion-exchange high performance liquid chromatography (HPLC) or ion chromatography (IC) coupled to ICP-MS. This document is applicable to the fertilizing product blends where a blend is a mix of two or more fertilising products belonging to the categories of fertilizers, liming material, soil improvers, growing media, inhibitors and plant biostimulants, and where soil improvers and/or growing media are the components with the highest percentage in the blend by mass or volume, or in the case of products in liquid form by dry mass. If the soil improvers and/or growing media are not the components with the highest percentage in the blend, the document relevant to the component with the highest percentage in the blend applies. In case a blend is composed of fertilising products mixed in equal quantities, the user of the document decides which standard to apply. NOTE A soil improver consists of a single bulky (volume-building) component or a mix of bulky (volume-building) components (for example peat, wood fibres, coconut coir, compost, expanded perlite).
