(Main)Flame arresters - Performance requirements, test methods and limits for use (ISO 16852:2016)
Flame arresters - Performance requirements, test methods and limits for use (ISO 16852:2016)
ISO 16852:2016 specifies the requirements for flame arresters that prevent flame transmission when explosive gas-air or vapour-air mixtures are present. It establishes uniform principles for the classification, basic construction and information for use, including the marking of flame arresters, and specifies test methods to verify the safety requirements and determine safe limits of use.
This International Standard is valid for pressures ranging from 80 kPa to 160 kPa and temperatures ranging from −20 °C to + 150 °C.
NOTE 1 For flame arresters with operational conditions inside the scope, but outside atmospheric conditions, see 7.4.
NOTE 2 In designing and testing flame arresters for operation under conditions other than those specified above, this International Standard can be used as a guide. However, additional testing related specifically to the intended conditions of use is advisable. This is particularly important when high temperatures and pressures are applied. The test mixtures might need to be modified in these cases.
NOTE 3 An additional standard IMO MSC/Circ. 677 for maritime application from IMO (International Maritime Organization) exists.
ISO 16852:2016 is not applicable to the following:
- external safety-related measurement and control equipment that might be required to keep the operational conditions within the established safe limits;
NOTE 4 Integrated measurement and control equipment, such as integrated temperature and flame sensors as well as parts which, for example, intentionally melt (retaining pin), burn away (weather hoods) or bend (bimetallic strips), is within the scope of this International Standard.
- flame arresters used for explosive mixtures of vapours and gases, which tend to self-decompose (e.g. acetylene) or which are chemically unstable;
- flame arresters used for carbon disulphide, due to its special properties;
- flame arresters whose intended use is for mixtures other than gas-air or vapour-air mixtures (e.g. higher oxygen-nitrogen ratio, chlorine as oxidant, etc.);
- flame arrester test procedures for internal-combustion compression ignition engines;
- fast acting valves, extinguishing systems and other explosion isolating systems.
Flammendurchschlagsicherungen - Leistungsanforderungen, Prüfverfahren und Einsatzgrenzen (ISO 16852:2016)
Diese Internationale Norm legt die Anforderungen an Flammendurchschlagsicherungen fest, die Flammendurchschläge bei Vorhandensein von explosionsfähigen Gas-Luft- oder Dampf-Luft-Gemischen verhindern. Sie stellt einheitliche Grundsätze für die Klassifizierung, die grundlegende Konstruktion und die Informationen für den Einsatz einschließlich der Kennzeichnung von Flammendurchschlagsicherungen auf und legt Prüfverfahren zur Überprüfung der sicherheitstechnischen Anforderungen und zur Bestimmung der sicheren Einsatzgrenzen fest.
Diese Internationale Norm gilt für Drücke von 80 kPa bis 160 kPa und für Temperaturen von −20 °C bis +150 °C.
ANMERKUNG 1 Für Flammendurchschlagsicherungen unter Betriebsbedingungen innerhalb des Anwendungsbereichs, aber außerhalb der atmosphärischen Bedingungen siehe 7.4.
ANMERKUNG 2 Diese Internationale Norm kann für Betriebsbedingungen, die von den oben festgelegten abweichen, als Leitlinie für die Auslegung und Prüfung von Flammendurchschlagsicherungen, dienen. Zusätzliche Prüfungen, insbesondere hinsichtlich der vorgesehenen Einsatzbedingungen, sind jedoch ratsam. Dies ist besonders bei hohen Temperaturen und Drücken wichtig. Die Prüfgemische müssen in diesen Fällen möglicherweise verändert werden.
ANMERKUNG 3 Es ist eine zusätzliche Norm IMO MSC/Circ. 677 für die Anwendung auf See von der IMO (Internationale Seeschifffahrts-Organisation) vorhanden.
Diese Internationale Norm gilt nicht für:
externe sicherheitsrelevante Mess- und Überwachungseinrichtungen, die erforderlich sind, um die Betriebsbedingungen innerhalb der festgelegten sicheren Grenzen zu halten;
ANMERKUNG 4 Eingebaute Mess- und Überwachungseinrichtungen, wie z. B. integrierte Temperatur- und Flammenmessfühler sowie Bauteile bei denen es beispielsweise beabsichtigt ist, dass sie schmelzen (Rückhaltestift), wegbrennen (Wetterhauben) oder sich verformen (Bimetallstreifen), fallen in den Anwendungsbereich dieser Internationalen Norm.
Flammendurchschlagsicherungen für explosionsfähige Gemische aus Dämpfen und Gasen, die zum Selbstzerfall neigen (z. B. Acetylen) oder die chemisch instabil sind;
Flammendurchschlagsicherungen, die bei Schwefelkohlenstoff eingesetzt werden, da dieser spezielle Eigenschaften besitzt;
Flammendurchschlagsicherungen, die bestimmungsgemäß für andere Gemische als Gas-Luft- oder Dampf Luft-Gemische (z. B. höheres Verhältnis Sauerstoff-Stickstoff, Chlor als Oxidationsmittel usw.) eingesetzt werden sollen;
Prüfverfahren für Flammendurchschlagsicherungen an Verbrennungsmotoren mit Kompressionszündung;
Schnellschlussventile, Löschsysteme und andere Explosionsentkoppelungssysteme.
Arrête-flammes - Exigences de performance, méthodes d'essai et limites d'utilisation (ISO 16852:2016)
ISO 16852:2016 internationale spécifie les exigences applicables aux arrête-flammes qui préviennent la transmission d'une flamme en présence de mélanges explosifs gaz-air ou vapeur-air. Elle établit des principes homogènes pour la classification, la construction de base et les informations pour l'utilisation, y compris le marquage des arrête-flammes, et spécifie des méthodes d'essai permettant de vérifier les exigences de sécurité et de déterminer des limites de sécurité d'utilisation.
La présente Norme internationale est valide pour des pressions comprises entre 80 kPa et 160 kPa et des températures comprises entre −20 °C et +150 °C.
NOTE 1 Pour les arrête-flammes avec des conditions de fonctionnement qui relèvent du domaine d'application, mais qui sont en dehors des conditions atmosphériques, voir 7.4.
NOTE 2 Lors de la conception et des essais des arrête-flammes destinés à fonctionner dans des conditions autres que celles spécifiées ci-dessus, la présente Norme internationale peut être utilisée comme guide. Toutefois, il est conseillé d'effectuer des essais supplémentaires se rapportant spécifiquement aux conditions d'utilisation prévues. Cela est particulièrement important lorsque des températures et des pressions élevées sont appliquées. Les mélanges d'essai pourraient avoir besoin d'être modifiés dans ces cas.
NOTE 3 Il existe une norme supplémentaire IMO MSC/Circ. 677 pour l'application maritime émise par l'Organisation maritime internationale (OMI).
ISO 16852:2016 n'est pas applicable aux cas suivants:
- appareils externes de mesurage et de commande liés à la sécurité qui peuvent être nécessaires pour maintenir les conditions de fonctionnement dans les limites de sécurité établies;
NOTE 4 Les équipements intégrés de mesurage et de commande, par exemple des capteurs intégrés de température et de flamme, de même que des pièces qui, par exemple, sont prévues pour fondre (clavette d'arrêt), brûler (abri contre les intempéries) ou se courber (bandes bimétalliques), relèvent du domaine d'application de la présente Norme internationale.
- arrête-flammes utilisés pour des mélanges explosifs de vapeurs et de gaz qui ont tendance à s'autodécomposer (par exemple l'acétylène) ou qui sont chimiquement instables;
- arrête-flammes utilisés pour le disulfure de carbone, du fait de ses propriétés spécifiques;
- arrête-flammes destinés à être utilisés pour des mélanges autres que des mélanges gaz-air ou vapeur-air (par exemple avec un rapport oxygène-azote plus élevé, avec du chlore en tant qu'oxydant, etc.);
- modes opératoires d'essai des arrête-flammes pour les moteurs à combustion interne et à allumage par compression;
- soupapes à action rapide, systèmes de coincement et autres systèmes d'isolement d'explosion.
Plamenske zapore - Zahtevane lastnosti, preskusne metode in omejitve uporabe (ISO 16852:2016)
Ta mednarodni standard določa zahteve za plamenske zapore, ki preprečujejo širjenje plamena v prisotnosti eksplozivnih mešanic plinov in zraka ali hlapov in zraka. Uveljavlja enotna načela za razvrstitev, osnovno konstrukcijo in informacije za uporabo, vključno z označevanjem plamenskih zapor, ter določa preskusne metode za preverjanje varnostnih zahtev in določanje varnih omejitev uporabe.
Ta mednarodni standard se uporablja za tlake med 80 kPa in 160 kPa ter temperature
med −20 °C in 150 °C.
OPOMBA 1: Za plamenske zapore s pogoji delovanja, ki so znotraj določenega obsega vendar zunaj atmosferskih pogojev, glej točko 7.4.
OPOMBA 2: Pri načrtovanju in preskušanju plamenskih zapor za delovanje v pogojih, ki se razlikujejo od zgoraj določenih, se lahko ta mednarodni standard uporabi kot vodilo, vendar se priporoča izvedba dodatnih preskusov za predvidene pogoje uporabe. To je pomembno zlasti, kadar je proizvod izpostavljen visokim temperaturam in tlaku. Preskusne mešanice je v teh primerih morda treba spremeniti.
OPOMBA 3: Obstaja dodatni standard IMO MSC/Circ. 677 za pomorsko uporabo, ki ga je sestavila Mednarodna pomorska organizacija (IMO).
Ta mednarodni standard se ne uporablja za:
– zunanjo varnostno merilno in nadzorno opremo, ki je morda potrebna za vzdrževanje
delovnih pogojev znotraj določenih varnih omejitev;
OPOMBA 4: Vgrajena merilna in nadzorna oprema, kot so vgrajeni senzorji temperature in plamena, ter deli, ki se na primer namensko topijo (zatiči), zgorijo (zaščita pred vremenskimi vplivi) ali se upogibajo
(dvokovinski trakovi), spadajo na področje uporabe tega mednarodnega standarda.
– plamenske zapore, ki se uporabljajo za eksplozivne mešanice samorazgradljivih
(npr. acetilen) ali kemično nestabilnih hlapov in plinov;
– plamenske zapore, ki se uporabljajo za ogljikov disulfid, zaradi njegovih posebnih lastnosti;
– plamenske zapore, ki se uporabljajo za mešanice, ki niso mešanice plinov in zraka ali hlapov in zraka (npr.
mešanice z višjim razmerjem kisika proti dušiku, mešanice s klorom kot oksidantom itd.);
– preskusne postopke za plamenske zapore za motorje z notranjim izgorevanjem in kompresijskim vžigom;
– hitro delujoče ventile, gasilne sisteme in druge sisteme za izolacijo eksplozij.
