Glass in buildings — Insulating glass — Part 3: Gas concentration and gas leakage
ISO 20492-3:2010 specifies two methods of test for insulating glass units, including a determination of the gas leakage rate and a determination of gas concentration tolerances. The two methods designated as approach 1, which is intended for use in markets such as North America, and approach 2, which is intended for use in markets such as Europe.
Glass in buildings - Insulating glass — Part 2: Chemical fogging tests
ISO 20492:2008 establishes two methods for testing the resistance to fogging of pre-assembled, permanently sealed insulating glass units or insulating glass units with capillary tubes intentionally left open. The two methods are designated as approach 1 for markets such as North America, and approach 2 for markets such as Europe.
ISO 20492:2008 is not applicable to sealed, insulating glass units…
Glass in buildings - Insulating glass — Part 1: Durability of edge seals by climate tests
ISO 20492-1:2008 establishes two methods for testing the durability of edge seals of insulating glass units by means of climate tests. The two methods are designated as approach 1 for markets such as North America and approach 2 for markets such as Europe.
ISO 20492-1:2008 is applicable to pre-assembled, permanently sealed, insulating glass units with one or two airspaces, and with capillary…
Matériaux métalliques — Essai de dureté Brinell — Partie 3: Étalonnage des blocs de référence
L'ISO 6506-3 :2014 spécifie une méthode pour l'étalonnage des blocs de référence à utiliser pour la vérification indirecte des machines d'essai de dureté Brinell, comme décrite dans l'ISO 6506‑2.
Les procédures nécessaires pour assurer la traçabilité métrologique de la machine d'étalonnage sont également spécifiées.
Matériaux métalliques — Essai de dureté Brinell — Partie 2: Vérification et étalonnage des machines ...
L'ISO 6506-2 :2017 spécifie des méthodes de vérifications directe et indirecte des machines d'essai utilisées pour la détermination de la dureté Brinell conformément à l'ISO 6506‑1 et spécifie également quand ces deux types de vérification doivent être réalisées.
La vérification directe implique de contrôler que les paramètres individuels de performance de la machine se situent à l…
