4.1.3 Marking Configuration. The style and location of the markings are left to the manufucturer to establish. The markings must include the manufacturer’s identification and model number (part number) or code, e.g., CT 324). followed by the fuel gas identification and then the maximum cutting capacity of the nozzle. e.g.. A 6 mm, Example; Acnie Mig. CT 12-0 A 6 miii. If necessary. more than one line may be used to mark the infoniiation on the nozzle.
4.2 Safcty and ilcaith Rcquircmcnts. The manufacturer shall make available the detailed instructions for the proper settings of the cutting nozzles. This information must include the recommended pressure settings in kilopascak (kPa) and the tiow rates in liters per nilnute (Umin for the oxygen and fuel gas required. These settings should give the operator acceptable performance under normal operating conditions.
The manufacturer shall make the safety information available for the proper use and operation of the cutting nozzle and related equipment used for oxyfuel cutting. This information should be in the form of instruction literature or imprinted on the product packaging.
