Overview

EN 14276-1:2006/FprA1 (CEN) is the European Standard amendment that sets general requirements for vessels used in refrigerating systems and heat pumps. Prepared by CEN/TC 182, this draft amendment (FprA1:2010) updates EN 14276-1:2006 to align vessel design, materials, fabrication and testing with more recent normative references and EU pressure-equipment requirements (see informative Annex ZA and EU Directive 97/23/EC). The amendment focuses on vessel-specific rules for pressure equipment in refrigeration and heat‑pump applications.

Key topics and technical requirements

• Scope and alignment: Updates normative references to current standards such as EN 378-1/2/4 (2008 series), EN 13445 (Unfired pressure vessels - 2009 series), and relevant EN ISO standards (e.g., EN ISO 6892-1 for tensile testing, EN ISO 4063 for welding nomenclature).
• Materials and documentation: Material traceability and certificates per EN 10204 are required for main pressure‑bearing parts (categories II–IV use 3.1/3.2 documents); filler materials require 2.2 test reports. Impact testing and minimum test temperatures reference EN 13445-2 Annex B or the standard’s Annex A.
• Design methods: Primary method is Design by Formula (DBF); Design by Analysis (DBA) and experimental techniques (Annex E) are permitted as supplements or alternatives. Minimum wall thickness follows EN 13445-3.
• Corrosion allowances: For internal surfaces in contact with listed HFC refrigerants, internal corrosion is considered negligible and a corrosion allowance of 0 mm may be used (manufacturer may choose larger values). External corrosion allowance can be 0 mm if adequate pre-service protection (paint, plating, vapor barriers) is applied and maintained.
• Manufacture and joining: Welding and brazing requirements reference EN 13445-3/4 and EN 12517-2 acceptance criteria; manufacturers must establish procedures and quality levels for brazed joints.
• Testing and inspection: Tensile, impact, pneumatic and acoustic emission test clauses are updated to reference current EN/ISO test standards and annex modifications included in the amendment.

Applications and users

This standard is essential for:

• Manufacturers and fabricators of pressure vessels for refrigerating systems and heat pumps
• Design engineers and thermal‑fluids specialists specifying vessel materials, thickness and safety margins
• Inspection bodies, notified bodies and conformity assessors enforcing Pressure Equipment Directive compliance
• HVAC‑R project managers, plant owners and maintenance teams ensuring safe operation and documentation

Keywords: EN 14276-1, pressure equipment, refrigerating systems, heat pumps, pressure vessels, CEN, EN 13445, EN 378, material certification, corrosion allowance, welding and testing.

Related standards

• EN 378‑1/2/4 (Refrigerating systems and heat pumps)
• EN 13445 (Unfired pressure vessels) Parts 2–6, 8
• EN 10204 (Inspection documents)
• EN ISO 6892‑1, EN ISO 4063, EN 12517‑2

This amendment harmonises vessel requirements with modern material, fabrication and safety standards to support reliable, compliant refrigeration and heat‑pump pressure equipment.
