EN ISO 20088-1:2016

Determination of the resistance to cryogenic spillage of insulation materials - Part 1: Liquid phases (ISO 20088-1:2016)

ISO 20088-1:2016 describes a method for determining the resistance to liquid cryogenic spillage on cryogenic spillage protection (CSP) systems. It is applicable where CSP systems are installed on carbon steel and will be in contact with cryogenic fluids.
Liquid nitrogen is used as the cryogenic medium since it has a lower boiling point than liquid natural gas or liquid oxygen and it is not flammable. Additionally, it can be safely used for experiment.
Future parts of the standard will cover vapour phase and jet exposure conditions.
The test laboratory is responsible to conduct an appropriate risk assessment according to local regulation in order to consider the impact of liquid and gaseous nitrogen exposure to equipment and personnel.

Bestimmung der Beständigkeit von Isoliermaterialien bei kryogenem Auslaufen - Teil 1: Flüssigkeit (ISO 20088-1:2016)

Dieser Teil von ISO 20088 beschreibt ein Verfahren zur Bestimmung der Beständigkeit von kryogenen Auslaufschutzsystemen (CSP) bei kryogenem Auslaufen. Es ist anwendbar, wenn CSP Systeme auf Kohlen-stoffstahl installiert sind und sich in Kontakt mit kryogenen Flüssigkeiten befinden.
Als kryogenes Medium wird flüssiger Stickstoff verwendet, da er einen niedrigeren Siedepunkt als flüssiges Erdgas oder flüssiger Sauerstoff hat. Darüber hinaus kann er sicher bei Versuchen verwendet werden.
Zukünftige Teile der Norm befassen sich mit der Dampfphase und der Exposition unter Hochdruckstrahl-bedingungen.
Das Prüflabor ist für die Durchführung einer angemessenen Risikobewertung nach örtlichen Vorschriften verantwortlich, um die Auswirkung der Exposition von flüssigem und gasförmigem Stickstoff auf die Ausrüstung und das Personal zu prüfen.

Détermination de la résistance des matériaux d'isolation thermique suite à un refroidissement cryogénique - Partie 1: Phase liquide (ISO 20088-1:2016)

ISO 20088-1:2016 décrit une méthode pour déterminer la résistance à une fuite cryogénique liquide sur les systèmes de Protection contre les Fuites Cryogéniques (CSP). Il s'applique quand des systèmes CSP sont installés sur de l'acier au carbone et seront en contact avec des fluides cryogéniques.
L'azote liquide est utilisé comme milieu cryogénique, puisqu'il a un point d'ébullition plus bas que le gaz naturel liquéfié ou l'oxygène liquide. Il peut de plus être utilisé sans danger pour l'expérimentation.
Les parties à venir du présent document traiteront des conditions en phase vapeur et d'émission sous forme de jet.
Il est de la responsabilité du laboratoire d'essai de réaliser une appréciation adéquate du risque suivant la réglementation locale afin de prendre en compte l'impact de l'exposition à l'azote liquide et gazeux sur les équipements et le personnel.

Ugotavljanje obstojnosti izolacijskih materialov pri razlitju v kriogenem področju - 1. del: Tekoča faza (ISO 20088-1:2016)

Ta del standarda ISO 20088 1. del opisuje metodo za ugotavljanje obstojnosti pri razlitju v kriogenem področju v sistemih CSP. Uporablja se, kjer so sistemi nameščeni na ogljikovo jeklo in bodo v stiku s kriogenimi tekočinami. Kot kriogen medij se uporablja tekoči dušik, saj ima nižjo točko vretja kot tekoči zemeljski plin ali tekoči kisik. Poleg tega ga je mogoče varno uporabljati pri eksperimentih. Prihodnji deli standarda bodo zajemali fazo izparevanja in pogoje izpostavljenosti visokotlačnega curka.
