The AD 2000-Merkbl？tter of the HP Series deal with the rules covering the design and manufacture of pressure vessels and pressure vessel components that are wholly or predominantly under static load, accessory housings and their joining with non-pressure-containing components, e.g. by welding. They follow up the AD 2000-Merkbl？tter of the W Series and specify the tests to be performed before, during and after manufacture, either by the relevant third party or by the manufacturer. For piping, AD 2000-Merkbl？tter HP 100 R, HP 110 R, HP 120 R and HP 512 R apply. For accessory housings, AD 2000-Merkblatt A 4 shall also be noted.
If the AD 2000-Merkbl？tter of the HP Series contain no provisions for the processing and testing of individual materials, agreement shall be reached between the manufacturer, customer/user and relevant third party.
For non-metallic materials, the AD 2000-Merkbl？tter of the N Series shall also be noted.
Where a vessel is composed of several chambers, it shall be classified in the highest category applicable to the individual chambers. If a chamber contains several fluids, classification shall be on the basis of whichever fluid requires the highest category.
