AS 2809.1 pdf download.Road tank vehicles for dangerous goods
This Standard specifies general requirements for the design, construction, testing, maintenance and inspection of road tank vehicles, irrespective of the cargo, that are intended for the road transport of dangerous goods. The Standard deals with vehicles that are designed and constructed specifically as road tank vehicles. This Standard is applicable also to conventional vehicles that carry portable or demountable tanks which are filled or discharged while on the vehicle and as a consequence are deemed to be a road tank vehicle for the purposes of the AS 2809 (see Note 1). NOTE 1 This does not include single filling or discharge of a portable tank in intermodal service. NOTE 2 The general vehicle and safety requirements are regulated by the Australian Design Rules (ADR) for motor vehicles issued by the Australian Commonwealth Government; these rules are outside the scope of this Standard. NOTE 3 Throughout this Standard the term “road tank vehicle” is used and has the same meaning as “tanker”.
Road tank vehicles intended for the transport of dangerous goods shall conform with this Standard, and with such other parts of the AS 2809 series as relevant to the hazards of the particular cargo. Where a cargo has two characteristics, e.g. flammable and toxic and, or where a road tank vehicle is switched from one cargo to another, the requirements of all relevant parts shall apply.
