    1. Slags arising from the manufacture of iron and carbon steel (including low alloy steel) excluding those slags which have been specifically produced to meet both national and relevant international requirements and standards [2]
    2. Stainless steel of the 300 series with low sulphur content and with an austenitic ASTM (or equivalent standard) grain size number of 5 or greater; or 2. Equivalent materials which are both cryogenic and H2-compatible; and d. With internal diameters of 1 m or greater and effective lengths of 5 m or greater. 1B229 Water-hydrogen sulphide exchange tray columns and 'internal contactors', as follows: N.B.: For columns which are specially designed or prepared for the production of heavy water see 0B004. a. Water-hydrogen sulphide exchange tray columns, having all of the following characteristics: 1. Can operate at pressures of 2 MPa or greater; 2. Constructed of carbon steel having an austenitic ASTM (or equivalent standard) grain size number of 5 or greater; and 3. With a diameter of 1,8 m or greater; b. 'Internal contactors' for the water-hydrogen sulphide exchange tray columns specified in 1B229.a. Technical Note: 'Internal contactors' of the columns are segmented trays which have an effective assembled diameter of 1,8 m or greater, are designed to facilitate countercurrent contacting and are constructed of stainless steels with a carbon content of 0,03 % or less. These may be sieve trays, valve trays, bubble cap trays, or turbogrid trays. 1B230
