Welding and allied processes - Determination of hydrogen content in arc weld metal (ISO 3690:2012)
ISO 3690:2011 specifies the sampling and analytical procedure for the determination of diffusible hydrogen in martensitic, bainitic, and ferritic steel weld metal arising from the welding of such steels using arc welding processes with filler metal.
The techniques specified in ISO 3690:2011 include collection of diffusible hydrogen via displacement of mercury or collection into a headspace filled with an inert gas such as argon. The amount of hydrogen collected is determined by measuring the displaced volume in the former and by, for example, thermal conductivity in the latter.
The temperature for collection of diffusible hydrogen is controlled to avoid thermal activation of non-diffusible hydrogen.
Schweißen und verwandte Prozesse - Bestimmung des Wasserstoffgehaltes im Lichtbogenschweißgut (ISO 3690:2012)
Diese Internationale Norm legt Anforderungen für das Verfahren der Prüfstückherstellung und der Analyse zur Bestimmung des diffusiblen und residuellen Wasserstoffs im Schweißgut martensitischer, bainitischer und ferritischer Stähle fest, das durch Lichtbogenschweißen mit Schweißzusatz hergestellt wurde.
Bei den in dieser Internationalen Norm beschriebenen Techniken wird diffusibler Wasserstoff zum einen mittels Quecksilberverdrängung, zum anderen in einem mit Inertgas, z. B. Argon, gefüllten Kopfraum auf-gefangen. Im ersten Fall wird die aufgefangene Wasserstoffmenge durch Messung des verdrängten Volumens bestimmt, im zweiten Fall durch Messung der Wärmeleitfähigkeit.
Die Temperatur wird beim Auffangen des diffusiblen Wasserstoffs kontrolliert, um eine thermische Aktivierung nicht diffusiblen Wasserstoffs zu vermeiden.
Darüber hinaus kann die Messung des diffusiblen Wasserstoffs durch Anwendung einer schnellen Methode (kurze Auffangzeit) bei höheren Temperaturen ausgeführt werden.
Soudage et techniques connexes - Détermination de la teneur en hydrogène dans le métal fondu pour le soudage à l'arc (ISO 3690:2012)
L'ISO 3690:2012 spécifie le mode opératoire d'échantillonnage et d'analyse pour la détermination de l'hydrogène diffusible dans le métal fondu en acier martensitique, bainitique et ferritique résultant du soudage de ces aciers avec des procédés de soudage à l'arc avec métal d'apport.
Les techniques spécifiées dans l'ISO 3690:2012 comprennent la collecte de l'hydrogène diffusible par déplacement de mercure ou la collecte dans un espace de tête rempli d'un gaz inerte, tel que l'argon. La quantité d'hydrogène collectée est déterminée en mesurant le volume déplacé pour la première technique et, par exemple, la conductivité thermique pour la seconde.
La température de collecte de l'hydrogène diffusible est régulée afin d'éviter l'activation thermique de l'hydrogène non diffusible.
Varjenje in sorodni postopki - Določevanje vodika v čistih varih pri obločnem varjenju (ISO 3690:2012)
Ta mednarodni standard opisuje, kako se lahko mednarodni standardi, ki obravnavajo ergonomijo fizikalnega okolja, uporabljajo za ljudi s posebnimi potrebami, ki bi bili sicer izključeni iz področja uporabe teh standardov. Pripravljen je v skladu z načeli dostopnega načrtovanja iz vodila ISO/IEC 71 in na podlagi podatkov iz ISO/TR 22411. Standard ni omejen na nobeno posebno okolje, ampak določa splošna načela, ki omogočajo oceno in vrednotenje, pri čemer lahko prispeva k razvoju standardov za posebna okolja. Uporablja se za grajeno okolje ter za druga notranja okolja, okolja v vozilu in zunanja okolja. Prav tako ni omejen na posebne okoljske elemente; vključuje oceno akustičnega okolja, temperaturnega okolja, osvetlitve, kakovosti zraka in drugih okoljskih dejavnikov, za katere se lahko šteje, da vplivajo na zdravje, udobje in delovanje oseb s posebnimi potrebami v posameznem okolju. Uporablja se za vse uporabnike takšnih okolij, za katere se šteje, da imajo posebne potrebe.
