22、cap for the adaptor for bottom loading and unloading, the subject of this European Standard, is the third closure device providing additional confinement of the dangerous substances within the tank when fitted. Additionally, when fitted, it provides mechanical protection for the sealing face of the
23、adaptor nose. BS EN 16249:2013EN 16249:2013 (E) 6 1 Scope This European Standard is applicable to the cap used to provide protection and end closing for the adaptor for bottom loading and unloading of tanks for the transport of dangerous goods. It specifies the performance requirements, critical dim
24、ensions and tests necessary to verify the compliance of the equipment with this European Standard. The equipment specified by this European Standard is suitable for use with liquid petroleum products and other dangerous substances of Class 3 of ADR 1)(flammable liquids) that have a vapour pressure n
25、ot exceeding 110 kPa at 50 C, including petrol, and that are not sub-classified as toxic or corrosive. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
