What is this standard about?
This standard is about how to forge steel that will used in pressurized equipment. This part specifies the technical delivery conditions of forgings for pressure purposes, made of nickel steels, for use at low temperatures.
Who is this standard for?
- Design engineers
- Importers/steel stockists
- Purchasing staff
- Quality engineers
- Quality managers
Why should you use this standard?
It enables conformity to the essential requirements of Directive 2014/68/EU (PED) on pressure equipment – see Note below.
What’s changed since the last update?
Some significant changes have been made since the 1999 version of this standard. They include:
- Updating of the normative references
- General alignment of the requirements with EN 10222-1
- Updating of the ordering information in chapter 5
- Table 1 containing values and statements on the heat treatment of the steels updated
- New Table 4 containing values for the mechanical properties at room temperature
- Updating of the values for the chemical composition and mechanical properties for the steel grades covered by this part of the EN 10222 series
- New sub Clause 6.7 “Resistance to hydrogen induced cracking” inserted in the standard
- Updating of Annex ZA in relationship with EU Directive 2014/68/EU
Note: Once this standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this standard and does not presume adequacy of the material to a specific item of equipment.
Consequently, the technical data stated in this material standard must be assessed against the design requirements of the specific item of equipment to check that the Essential Safety Requirements of Directive 2014/68/14 are met.
The series BS EN 10222–1, BS EN 10222-2, BS EN 10222-3, BS EN 1222-4 and BS EN 10222−5 is structured so that the data related to different materials is in the part allocated for that material.
The presumption of conformity to the Essential Safety Requirements of Directive 2014/68/EU depends on both the text in part 1 and the data in part 2, 3, 4 or 5.
General information on technical delivery condition is given in BS EN 10021.
