Préface

La présente constitue la première édition de la norme CAN/CSA-M427, Matériaux pour conduits d’aérage des mines : caractéristiques antistatiques et de tenue au feu. Cette nome a été élaborée dans le but d’éprouver la tenue au feu des conduits d’aérage, de permettre leur évaluation et d’empêcher la propagation d’un éventuel incendie. Un incendie se déclarant à l’intérieur d’une mine souterraine peut être très dangereux en raison du nombre limité d’issues de secours.

Les conduits et la toile d’aérage sont souvent fabriques de matériaux polymériques qui ont la particularité de propager le feu.

Cette norme énonce les méthodes d’essai visant à assurer l’utilisation sécuritaire des matériaux pour conduits d’aérage des mines souterraines en déterminant leur inflammabilité et leurs caractéristiques antistatiques.

Domaine d'application

1.1

La présente norme définit les exigences en matière de caractéristiques antistatiques et de tenue au feu des matériaux neufs destinés à la fabrication des conduits d'aérage des mines souterraines.

1.2

Ces matériaux peuvent être subdivisés en deux catégories: matériaux pour conduits rigides mono pièces et matériaux pour écrans flexibles en tôle. (Ces derniers peuvent être confectionnés en sections de pièces de tôle ou en conduits.) Les essais et exigences visant chaque catégorie sont légèrement différents, étant donné les propriétés physiques qui distinguent chaque catégorie. Toutefois, l'objectif de cette norme est d'uniformiser les critères d'évaluation des caractéristiques antistatiques et de tenue au feu pour chaque catégorie.

1.3

La norme répartit ces matériaux en quatre types:

(a) Type VH-AS – conduits à installer à la verticale ou à l'horizontale dans des mines à atmosphère explosive;

(b) Type VH – conduits à installer à la verticale ou à l'horizontale dans des mines à atmosphère non explosive;

(c) Type H-AS – conduits à installer à l'horizontale ou presque à l'horizontale dans des mines à atmosphère explosive;

(d) Type H – conduits à installer à l'horizontale ou presque à l'horizontale dans des mines à atmosphère non explosive.

Notes:

1. Les lettres V, H et AS signifient respectivement verticale, horizontale et antistatique.

2. Les conduits installés à la verticale présentent les conditions les plus rigoureuses à cause de la possibilité «d'effet de cheminée» qui accélère la propagation des flammes.

1.4

Sous réserve de chapitre 5, cette norme ne traite pas des produits de combustion ni de la dégradation des matériaux destinés aux conduits d'aérage par suite d'une exposition aux flammes ou à la chaleur.

Note. Bien que l'objet de la norme soit d'établir des critères raisonnables de tenue au feu des matériaux pour conduits d'aérage, il est entendu que dans des conditions autres que celles décrites dans la norme, la combustion de tels matériaux est possible.

Preface

This is the first edition of CSA Standard CAN/CSA-M42 7, Fire-Performance and Anristutic Requirements for Ventilation Materials. It was developed because a fire-resistance test for ventilation ducts has become necessary in order to permit evaluation of ducts and thus prevent fire spread. A fire in an underground mine can be very dangerous because of limited means of escape.

Ventilation tubing and brattice cloth are often made of polymeric materials that have the potential to spread to a fire once ignited.

This standard outlines the test methods necessary to ensure the safe use of ventilation tubing materials by determining their flammability and antistatic requirements for underground mines.

Scope

1.1

This Standard specifies the fire-performance and antistatic requirements for new (unused) ventilation materials for use in underground mines.

1.2

Ventilation materials can be divided into two categories: rigid tubing and flexible sheeting. (The latter can be either used in the form of hanging sheets or made into tubing.) The physical differences between these two categories require that the tests and requirements be slightly different. The intent of this standard, however, is to ensure that the fire-performance and antistatic characteristics are evaluated in an equivalent manner.

1.3

This Standard covers ventilation material of the following types:

(a) Type VH-AS, intended for either vertical or horizontal applications in explosive atmospheres;

(b) Type VH, intended for either vertical or horizontal applications in nonexplosive atmospheres;

(c) Type H-AS, intended for horizontal or near-horizontal applications in explosive atmospheres;

(d) Type H, intended for horizontal or near-horizontal applications in nonexplosive atmospheres.

Notes:

(1) The letters V, H, and AS stand for Vertical, Horizontal, and Antistatic respectively.

(2) Vertical applications are the most severe because of the possibility of a chimney effect accelerating the spread of the fire.

1.4

This Standard does not address the products of combustion or of thermal degradation from ventilation materials subjected to fire or heating, except as noted in Clause 5.

Note: While the object of this Standard is to establish a reasonable level of fire-performance for ventilation materials, it is recognized that any ventilation material may burn under conditions different from those described in this Standard.

This part of IEC 62013 specifies requirements for the construction and testing of caplights, including caplights with a point of connection for another apparatus, for use in mines susceptible to firedamp (Group I – electrical apparatus for explosive gas atmospheres as defined in IEC 60079-0). It deals only with the risk of the caplight becoming a source of ignition.
