EN 13445 - Unfired Pressure Vessels is a standard that provides rules for
the design, fabrication, and inspection of pressure vessels
EN 13445 consists of 7 parts:
EN 13445-1 : Unfired pressure vessels - Part 1: General
EN 13445-2 : Unfired pressure vessels - Part 2: Materials
EN 13445-3 : Unfired pressure vessels - Part 3: Design
EN 13445-4 : Unfired pressure vessels - Part 4: Fabrication
EN 13445-5 : Unfired pressure vessels - Part 5: Inspection and testing
EN 13445-6 : Unfired pressure vessels - Part 6: Requirements for the
design and fabrication of pressure vessels and pressure parts constructed
from spheroidal graphite cast iron
EN 13445-8 : Unfired pressure vessels - Part 8: Additional requirements for
pressure vessels of aluminium and aluminium alloys
Parts 7 and 9 do exist but they are merely technical reports.
BS: 4515.This British Standard specifies requirements for the welding of
carbon, carbon manganese and low alloy steel pipelines with specified
minimum yield strengths not exceeding 500 N/mm2 and designed in
accordance with BS 8010-2 and BS 8010-3.
In addition to the definitive requirements it also requires the items
detailed in 1.4 to be documented. For compliance with this standard, both
the definitive requirements and the documented items have to be
satisfied.
The standard applies to pipes of outside diameter 21.0 mm and larger
having a thickness of 3.0 mm or greater.
