Securing credible environmentally relevant performance assessment methods in standards

IEC GUIDE 121:2023 specifies principles, requirements, and guidance for standard writers to identify whether an assessment method in their standard can be used to obtain an indication of the environmental performance of a product and to ensure that such assessment is credible.
This Guide applies to standards covering environmental performance of new products and as appropriate to standards covering environmental performance of second life products (e.g., refurbished or remanufactured).
This Guide is therefore intended to ensure that assessment methods developed by standard writers are credible. The credibility of an environmentally relevant performance assessment method is determined by taking into account all the related principles, namely representativeness, measurement repeatability, measurement reproducibility, measurement accuracy, cost of testing, as well as circumvention.
Environmentally relevant performance assessment methods can be present in many IEC standards (e.g., standards covering performance aspects of products), and not only those focused on the environment. This Guide will be applicable to those as well.
This Guide is not applicable to standards containing environmentally relevant performance assessment methods that are not assessed by test (e.g., assessment by inspection or simulation). Nor is it applicable to other aspects not linked to environment, such as EMC and EMF.

Assurer des méthodes d'évaluation crédibles et pertinentes de la performance pour l'environnement dans les normes

L'IEC GUIDE 121:2023 spécifie des principes, des exigences et des recommandations pour aider les rédacteurs de normes à déterminer si une méthode d'évaluation de leur norme peut être utilisée afin d'obtenir une indication de la performance environnementale d'un produit et à assurer la crédibilité de cette évaluation.
Le présent Guide s'applique aux normes qui traitent de la performance environnementale des produits neufs et, le cas échéant, aux normes qui traitent de la performance environnementale des produits de seconde vie (remis en état ou refabriqués, par exemple).
Le présent Guide vise donc à assurer la crédibilité des méthodes d'évaluation élaborées par les rédacteurs de normes. La crédibilité d'une méthode d'évaluation pertinente de la performance pour l'environnement est déterminée en tenant compte de tous les principes connexes, à savoir la représentativité, la répétabilité des mesures, la reproductibilité des mesures, l'exactitude des mesures, le coût des essais, l'anticontournement, ainsi que le réexamen des normes.
Les méthodes d'évaluation pertinentes de la performance pour l'environnement peuvent être présentes dans de nombreuses normes de l'IEC (par exemple, dans les normes qui traitent des aspects relatifs à la performance des produits), et pas seulement dans les normes axées sur l'environnement. Le présent Guide s'applique également à ces normes.
Le présent Guide ne s'applique ni aux normes qui contiennent des méthodes d'évaluation pertinentes de la performance pour l'environnement qui ne sont pas évaluées par des essais (par exemple, évaluation par examen ou simulation) ni aux autres aspects non liés à l'environnement, comme la compatibilité électromagnétique (CEM) et les champs électromagnétiques (EMF, Electromagnetic Fields).
Le présent Guide ne comprend aucune recommandation pour déterminer si tous les aspects pertinents pour l'environnement sont couverts par une norme de l'IEC. Le présent Guide ne donne pas non plus de recommandations pour déterminer si une méthode d'évaluation de la performance a été correctement identifiée comme pertinente pour l'environnement.
