This second edition cancels and replaces the first edition ISO The specimens shall be oriented with the notch perpendicular to the surface of the material. Corrosion-resistant valves shall be blast-cleaned with sand or other non-ferrous medium prior to shipment and shall not be coated, unless otherwise agreed. Pressure testing, including pipe pups if applicable, shall be carried out before coating of the valves.
All NDE of fabrication welds shall be carried out in the final heat-treated condition and shall be performed in accordance with written procedures.
BS EN ISO 14723:2009
Table 11 — Valve marking Item No. Corrosion tests to demonstrate corrosion resistance of the heat and heat-treatment batch combination of high alloy steels used for the manufacturing of the valve should be specified by the purchaser. Valves shall be tested with the seating and sealing surfaces free from sealant, except where the sealant 147223 the primary means of sealing.
Amazon Music Stream millions of songs. Protective covers shall be made of wood, wood fibre, plastic or metal and shall be securely attached to the valve ends by bolting, jso straps, steel clips or suitable friction-locking devices.
The purchaser shall specify which particular supplementary tests in Annex B ios be performed. Amazon Restaurants Food delivery from local restaurants. The choice of standard shall be by agreement.

The notch shall be placed perpendicular to the material surface at a location resulting in a maximum amount of HAZ material located in the resulting fracture. My doubt is, if these two specifications are different or are the same. If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained. Materials for external components shall be suitable for the subsea environment or shall be suitably protected.

If necessary for assembly, a lubricant with a viscosity not exceeding that of SAE 10W motor oil or equivalent may be used. For valves without a body cavity or drain connection, or downstream-seated valves, seat leakage shall be monitored at the respective downstream end of the valve the valve end downstream of the pressurized test fluid. If the valve manufacturer is responsible for the supply 1472 the valve and operator assembly, the valve manufacturer shall verify the suitability of the lifting points for the complete assembly.
Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
If the pressure rating of the isk pups is insufficient for the hydrostatic-shell test pressure, then the pups shall be welded to the valve following the valve-shell test and the valve and pup s tested at a pressure specified by the purchaser.
Supply pressure shall be stabilized prior to the start of pressure testing and shall be held for the minimum test durations listed in Tables 9 and
