ISO 14021:2016 specifies requirements for self-declared environmental claims, including statements, symbols and graphics, regarding products. It further describes selected terms commonly used in environmental claims and gives qualifications for their use. This International Standard also describes a general evaluation and verification methodology for self-declared environmental claims and specific evaluation and verification methods for the selected claims in this International Standard. ISO 14021:2016 does not preclude, override, or in any way change, legally required environmental information, claims or labelling, or any other applicable legal requirements.

ISO 14024:2018 establishes the principles and procedures for developing Type I environmental labelling programmes, including the selection of product categories, product environmental criteria and product function characteristics, and for assessing and demonstrating compliance. ISO 14024:2018 also establishes the certification procedures for awarding the label.

ISO 14025:2006 establishes the principles and specifies the procedures for developing Type III environmental declaration programmes and Type III environmental declarations. It specifically establishes the use of the ISO 14040 series of standards in the development of Type III environmental declaration programmes and Type III environmental declarations. ISO 14025:2006 establishes principles for the use of environmental information, in addition to those given in ISO 14020:2000 Type III environmental declarations as described in ISO 14025:2006 are primarily intended for use in business-to-business communication, but their use in business-to-consumer communication under certain conditions is not precluded.

This document describes a method for the determination of inorganic arsenic in algae by anion-exchange HPLC-ICP-MS following water bath extraction. Inorganic arsenic consists of arsenite, As(III) and arsenate, As(V). A representative test portion of the sample is treated with a diluted nitric acid and hydrogen peroxide solution in a heated water bath. Hereby the arsenic species are extracted into solution and As(III) is oxidised to As(V). The inorganic arsenic is selectively separated from other arsenic compounds using anion exchange HPLC (High Performance Liquid Chromatography) coupled on-line to the element-specific detector ICP-MS (Inductively Coupled Plasma Mass Spectrometry) for the determination of the mass fraction of inorganic arsenic. External calibration with solvent matrix-matched standards is used for quantification of the amount of inorganic arsenic. The method is based on method EN16802: Inorganic arsenic in food of plant and marine origin by HPLC-ICPMS, but covers more algae species. The present AsSugar species in certain algae can cause As peaks which might overlap with the As peaks related to the inorganic As. The current method includes a gradient elution method with quality criteria to ensure a correct identification of the inorganic arsenic.

This document describes a method for determining the amino acid profile of algal biomass. It specifies a method for the determination, in one single analysis, of the following amino acids: alanine, arginine, aspartic acid (combined with asparagine), cystine (dimer of cysteine, combined with cysteine), glutamic acid (combined with glutamine), glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tyrosine and valine. This method does not apply to the determination of tryptophan. The existing draft standard ISO/DIS 4214 – Milk and milk products – Determination of amino acids in infant formula and other dairy products will be evaluated and adapted.

This document describes a method for determining the total protein content of algal biomass. Therefore, an existing method for measurement and calculation will be adapted. The method consists of the measurement of the nitrogen content by a practical test method and the calculation of the protein content by a coefficient. The document will describe the test method for nitrogen measurement. As the coefficient usually used for protein determination (6.25) is too high for algae, the document will give a recommendation for a coefficient which is more specific to algae and thereby more accurate.

This document specifies a laboratory method for the quantification of phycocyanin content in the genus Arthrospira (Spirulina) by a spectrophotometric method.

This European standard specifies a laboratory method for the determination of the carotenoid content in microalgae. The method is based on the development of the chlorophyll a standard, which resulted in prEN 18034. This method has been validated for the microalgae species Nannochloropsis and Phaodactlylum. This standard is only validated for fucoxanthin, beta carotene and lutein content, but could be used for other carotenoids as well. Given small adaptations to be able to measure smaller concentrations, this method could also be used for macro algae. This standard is developed in CEN/TC 454/WG 6 Product test methods.

This document specifies a method for the quantitative determination of total uronic acids by High-Performance Anion Exchange Chromatography coupled with Pulsed Amperometric Detection (HPAEC-PAD) after acid hydrolysis of the samples. It provides a single analysis method for determining mannuronic, glucuronic, and guluronic acids in brown seaweed and alginate products.

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 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 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.
