1.1 General

This Standard provides a means of determining a concrete laboratory’s capability to test concrete and related materials. It provides for three levels of certification: basic concrete, concrete aggregate, and advanced concrete certification. Its purpose is to ensure that the services obtained from a concrete testing laboratory are of acceptable quality and performance. It also provides minimum requirements for the test equipment, qualifications of personnel who test concrete, and their performance in testing; however, this Standard should not be construed as a standard detailing the technical ability and expertise necessary to provide a comprehensive consulting service in concrete technology.

1.2 Laboratory certification

This Standard addresses

a) the requirements for laboratory certification; and

b) the administration of these requirements.

1.3 Terminology

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.1 Inclusions

This Standard specifies labeling requirements to disclose quantitative and qualitative information on well-to-gate carbon intensity (CI), including production pathway and the main supply chain attributes.

This Standard provides a harmonized disclosure approach based on data obtained using existing methodologies and lifecycle assessment (LCA) tools that are largely used to determine and report greenhouse gas (GHG) emissions associated with hydrogen production to estimate the hydrogen CI.

This Standard applies to the production of gaseous hydrogen. Liquefaction of hydrogen is considered part of conditioning and distribution of hydrogen and is out of scope.

This Standard provides a disclosure framework that applies to site-specific production units. It is applicable to different inventories such as actual hydrogen production batches from a given production site, average hydrogen production over a one-year or more period from a given production site, anticipated average hydrogen production from a planned production facility.

This Standard has been designed for hydrogen with a purity of 98% or greater to be applicable to all ISO 14687 hydrogen fuel qualities.

1.2 Exclusions

This Standard does not cover CI thresholds or limits used to define different categories of hydrogen.

This Standard does not provide an LCA method or model for assessing GHG emissions. Protocols and standards exist for this purpose and are referenced in this Standard.

This Standard does not cover information related to the additional carbon emission resulting from conditioning and transporting hydrogen from the producer to the end-user.

This Standard does not apply to hydrogen obtained by mixing hydrogen produced either in multiple sites or via multiple production pathways.

This Standard is not designed to apply to syngas or blends of hydrogen and other fuels.

1.3 Conflicts

In case of conflict between this Standard and federal, provincial, state, or local regulations, governmental regulations shall take precedence.

1.4 Terminology

In this Standard, “shall” is used to express a requirement, i.e., a provision that the end-user is obliged to satisfy in order to comply with this Standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the Standard.

1.5 Use of SI units

1.1 Inclusions

La présente norme fixe les règles de mise en forme pour le partage de l’information quantitative et qualitative sur l’intensité carbone (IC), du puits à la production, y compris la filière de production et les principaux attributs de la chaine d’approvisionnement.

La présente norme établit une approche harmonisée pour communiquer les données obtenues par l’application des méthodologies et des outils d’analyse du cycle de vie (ACV) déjà existants et qui sont largement utilisés dans le but de calculer les émissions de gaz à effet de serre (GES) de la production d’hydrogène afin d’estimer l’IC de l’hydrogène.

La présente norme s’applique à la production d’hydrogène gazeux; la liquéfaction est vue comme faisant partie du conditionnement et de la distribution de l’hydrogène et n’est donc pas incluse dans le domaine d’application.

La présente norme détermine une démarche de communication s’appliquant aux unités de production propres à des sites distincts. Elle s’applique à différentes quantités, comme les quantités réelles produites par un site donné, la production moyenne sur un an (ou plus) d’un site donné, ou la production moyenne attendue d’une installation de production prévue.

La présente norme a été conçue pour de l’hydrogène dont la pureté est d’au moins 98 % pour être compatible avec toutes les qualités du carburant hydrogène établies dans ISO 14687.

1.2 Exclusions

La présente norme ne traite pas des seuils ou limites des IC employées pour catégoriser l’hydrogène.

La présente norme ne fournit pas de méthode d’ACV ou de modèle pour l’évaluation des émissions de GES.

Note - Il existe déjà pour cela des protocoles et normes auxquels la présente norme fait référence.

La présente norme ne couvre pas les renseignements concernant les émissions de carbone additionnelles provenant du conditionnement de l’hydrogène et de son transport du site de production vers l’utilisateur final.

La présente norme ne s’applique pas à l’hydrogène obtenu par mélange de la production d’hydrogène de multiples sites ou de multiples filières de production.

La présente norme n’est pas conçue pour être appliquée au gaz de synthèse ou aux mélanges d’hydrogène et d’autres carburants.

1.3 Incompatibilité

En cas de conflit entre la présente norme et la règlementation fédérale, provinciale, étatique ou locale, la priorité doit être donnée à la règlementation gouvernementale.

1.4 Terminologie

Dans la présente norme, le terme « doit » indique une exigence, c’est-à-dire une prescription que l’utilisateur final doit respecter pour assurer la conformité à la norme; les formes verbales « il est recommandé » ou « il convient » indiquent une recommandation ou ce qu’il est conseillé, mais non obligatoire, de faire; et « peut » indique une possibilité ou ce qu’il est permis de faire.
