1 PURPOSE This Technical Specification defines Company material requirements for items that, because of malfunctioning or failure, would have the potential to create a safety hazard.
- SCOPE
2.1 This specification applies to materials used in pressure and structural load-carrying service in onsite sale of gas (SOG), third-party sale of equipment (SOE), and intercompany projects managed by Global Engineering and Manufacturing (GEM) Worldwide. Some examples include:
Note: This list is meant to serve as an example, and is not comprehensive.
- Pressure-containing parts and attachments (for example, piping and in-line components)
- Vessel supports and attachments (for example, saddles, skirts, baseplates, lifting lugs, and trunnions)
- Pressure-retaining bolting (for example, flange bolting)
- Load-carrying structural members [for example, pipe racks, cold-box chords (vertical columns), girts (face horizontal members), diagonal bracing, roof members, base members, and stressed panels]
- Load-bearing structural bolting
2.2 Any individual material purchase specifications that apply to a project provide the detailed requirements for those items. This document shall be read and applied in conjunction with those specifications.

- CERTIFICATION
4.1 Material certification shall meet all necessary statutory/code requirements of the country of use.
4.2 Unless permitted otherwise by the applicable statutes/codes in the country of use (for example, the PED, section 6), the minimum certification requirement for materials used in pressure or structural load-carrying service shall be either a mill certificate (for metallic material originating in the USA) or a Type 3.1 inspection certificate according to EN 10204.
Note: Excluded are bolting (see paragraph 4.3), unstressed panels, and steelwork required solely for supporting such panels.
4.2.1 Where the project-specific documentation or this general document refers to a mill or EN 10204 Type 3.1 inspection certificate, the certificate shall be in the form of a Material Test Report. This report shall include the results of mechanical tests and a full chemical analysis that refers to the cast or heat identification of the component.
Note: For aluminum materials, it is acceptable to follow the standard industry practice of determining the chemical composition of the ingot before further processing.
4.2.2 For mill or EN 10204 Type 3.1 certificates, all material shall be identified on the certificates with all of the following information:
- Heat number (if applicable)
- Brief item description
- Company purchase order number
- Company purchase order item number
- Company SAP material master
Certification that is not clearly identified in this manner will be returned to the supplier and payment will be withheld accordingly.
Note: The order number, order item number, and SAP material master do not apply to complete items of equipment. They apply to raw materials (for example, piping bulks) purchased directly by Company or on its behalf.
4.2.3 The name and position of the person attesting the results on the material certification shall be included on the test certificate.
4.3 Unless stated otherwise by a purchase specification or similar agreement, all pressure- retaining and structural bolting shall be lot certified with, as a minimum, a Certificate of Compliance or, in Europe, an EN 10204 Type 2.1 certificate.
4.4 For piping bulks (for example, pipe, elbows, tees, weldolets, socket fittings, and bolting), the supplier shall provide two sets of material certificates: one shipped with the item(s) and an identical, electronic set submitted on CD or by email to the Company requisitioner. The Company requisitioner will keep the copy for reference, for supplement to the site copy, or for archive by the Engineering Data department if the mechanical contractor does not return the certificates in the final production dossier.
4.5 Material certification for individual items of piping inline equipment (for example, valves) shall be supplied in accordance with the Vendor Data Requirement (VDR) forms issued with the order. Unless specified otherwise, material certification for individual items of equipment (for example, pressure vessels, and heat exchangers) shall be supplied in the final production dossiers.
- COUNTRY OF ORIGIN
5.1 All materials for items covered under the scope of this document shall originate from a “qualified” country except as defined in paragraph 5.2.
5.1.1 Countries of origin currently “qualified” by Company are; Austria, Belgium, Canada, Czech Republic, Denmark, Finland, France, Germany, Ireland, Italy, Japan, Luxembourg, Liechtenstein, The Netherlands, Norway, Mexico, Poland, Spain, South Korea, South Africa, Sweden, Switzerland, Taiwan, the United Kingdom, and the United States of America.
5.2 The use of materials from manufacturers in “unqualified” countries is not prohibited, but requires review and approval from Air Products.
- On a project specific basis, approvals shall be by means of re-testing the materials in question. Material retesting shall be in accordance with 4WEQ-1110.
- For items of equipment or raw materials that are purchased frequently from the same supplier, Company may apply alternative approval procedures. In such cases, details of the materials and proposed suppliers shall be submitted to Company for acceptance before submitting any quotation. Such requests will not be considered after the placement of a purchase order.
5.2.1 Heat exchangers and vaporisers made of aluminium alloys are exempted from country of origin requirements defined by this document.
5.3 The country of origin for items (finished product) and the raw materials from which the items are formed shall be traceable from the certification and/or marking.
- MATERIALS FOR EQUIPMENT SUBJECT TO THE EUROPEAN UNION PED
6.1 The European Pressure Equipment Directive (97/23/EC) (PED) requires an EN 10204 Type 3.2 inspection certificate for main pressure-bearing parts or, as an alternative, an EN10204 Type 3.1 certificate from a material manufacturer with a QA system certified by a competent body established within the European Community (see notes 1, 2 and 3).
-
- The EN 10204 Type 3.2 inspection certificate must be certified by a representative acceptable to or appointed by Air Products. Generally any European Notified Body will be acceptable to Air Products. If a Notified Body is not used, the supplier shall contact Air Products’ Inspection Department to establish who may be Air Products’ representative when applicable.
- If a Type 3.1 certificate is supplied instead of a Type 3.2, the Type 3.1 certificate must include the details of the material manufacturer’s QA system and certifying body established within the community. Otherwise, a copy of the relevant QA approval certificate shall be attached to the Type 3.1 certificate.
Note 1: Material (for example, plates, pipe, bars, and sections) from intermediary stockists or suppliers shall be accompanied by original inspection certificates (per paragraph 6.1) from the base/raw material manufacturer.
Note 2: Components (for example, welded pipe fittings and pipe fittings machined from bar) manufactured from materials such as plates and bars, where the properties have not been substantially modified by the component manufacturing process, shall be supplied with the original inspection certificate (per paragraph 6.1) from the base/raw material manufacturer.
Note 3: Where the component manufacturing process involves operations that may change the material’s properties (for example, forged pipe fittings, and dished ends), the inspection certificate (per paragraph 6.1) shall list the results of mechanical testing on the finished component. The chemical composition may be assumed unchanged from the original base/raw material certificate values.
6.2 The PED permits EN 10204 Type 2.2 certificates for some applications (for example, non-main pressure parts in categories I-IV equipment, attachments to categories II-IV equipment, and main pressure parts in category I equipment). For other parts (for example, bolting), EN 10204 Type 2.1 certificates are permitted.
6.3 The country of origin restrictions imposed by Section 5 also apply to CE-marked equipment.
6.4 For pressure equipment supplied as CE marked under the PED, the equipment’s CE mark and Declaration of Conformity are deemed evidence that its material certification satisfies the requirements of paragraph 4.2.
or such CE-marked items, material certificates for the equipment’s component parts are not required by Company unless specifically requested in the item’s purchase order or attachments (that is, listed in final documentation requirements). The CE mark and declaration of conformity will typically be sufficient for manual, control, and relief valves, but material certificates will generally be requested for pressure vessels and heat exchangers.
