There are three main ISO standards in this area from a materials point of view: Fusion welding ISO —2 Welding and allied processes — Classification of geometric imperfections in metallic materials — Part 2: Comprehensive quality requirements ISO Welding and allied processes — Nomenclature of processes and reference numbers ISO Destructive tests on welds in metallic materials — Transverse tensile testing ISO Paints and varnishes — Pull-off test for adhesion.
Arranging a global networking of the materials technology specialists of OGP members for the purpose of discussing the existing company and project specifications and available standards related to this discipline. Representative photographic examples of the change of appearance imparted to steel when blast-cleaned with different abrasives ISO —3 Part 3: Tees, Nozzles, Dimensions Part 5: Classification of steels into unalloyed and alloy steels based on chemical composition ISO —2 Steels — Classification — Part 2: It appears to be an active committee.
All other rights are reserved. These documents are normally based on, but include various degrees of supplements and amendments to international, national and industry standards. Assemblies; fittings; general quality requirements and testing Part 2: Numbers have not yet been given to the new Technical Committees.
This standard is presently at DIS ballot.
Electron and laser beam welding ISO —12 Specification and qualification of welding procedures for metallic materials — Welding procedure test — Part This document may provide guidance supplemental to the requirements of local legislation. ISO —5 Paints and varnishes — Corrosion protection of steel structures by protective paint systems — Part 5: Microhardness testing of welded joints ISO Seamless and welded except submerged arc-welded steel tubes for pressure purposes — Full peripheral ultrasonic testing for the detection of longitudinal imperfections ISO Seamless and welded except submerged arc-welded steel tubes for pressure purposes — Eddy current testing for the detection of imperfections ISO Seamless steel tubes for pressure purposes — Full peripheral ultrasonic testing for the detection of transverse imperfections ISO —1 Steel forgings and rolled or forged bars for pressure purposes — Technical delivery conditions — Part 1: Some of the key API standards which are important as regards material requirements are: Built upon decades of knowledge and expertise from dedicated members all around the world, NACE International is involved in every industry and area of corrosion prevention and control, from chemical processing and water systems to transportation and infrastructure protection.
The international materials standards work within many different work groups both at the international, national and at an industry level may be influenced. Mining and minerals BS Specification for design and construction of vessels and tanks in reinforced plastics BS Specification for limits of surface imperfections on elastomeric toroidal sealing rings O-rings. ISO Stainless steels — Chemical composition ISO Specification and qualification of welding procedures for metallic materials — General rules ISO —2 Specification and qualification of welding procedures for metallic materials — Welding procedure specification — Part 2: The recipient is obliged to inform any subsequent recipient of such terms.
In the present form the document does not suitably cover material requirements. Materials requirements and recommendations are embedded in the individual standards, with more general material recommendations and requirements in ISOpart 1 General recommendations and requirements.
ISO —2 Mechanical properties of corrosion resistant stainless steel fasteners — Part 2: Direct-hardening unalloyed and low-alloyed wrought steel in form of different black products ISO —18 Heat-treatable steels, alloy steels and free — cutting steels — Part So also with the accompanying welding and component standards. Disputes arising here from shall be exclusively subject to the jurisdiction of the courts of England and Wales.
In the event of any conflict or contradiction between the provisions of this document and local legislation, applicable laws shall prevail.

Unalloyed and alloyed steels with specified elevated temperature properties ISO —3 Seamless steel tubes for pressure purposes — Technical delivery conditions — Part 3: ISO —6 Part 6: Hardness test on arc welded joints ISO —2 Destructive tests on welds in metallic materials — Hardness testing — Part 2: Non-alloy and alloy Mo, Cr and CrMo steels with specified elevated temperature properties ISO —3 Steel forgings and rolled or forged bars for pressure purposes — Technical delivery conditions — Part 3: ISO Preparation of steel substrates before application of paints and related products — Surface roughness characteristics of 912 cleaned substrates.
Bolts, screws and studs. Arc and gas welding of copper and its alloys ISO —7 Specification and qualification of welding eemuw for metallic materials — Welding procedure test — Part 7: The focus of this standardisation is likely to be material and welding qualification and quality assurance.
Determining further networking arrangements, if agreed. ISO —6 Paints and varnishes — Evaluation of degradation of paint coatings — Designation of intensity, quantity and size of common types of defect — Part 6: The same materials and fabrication clauses basically applies here. These lists will hardly ever be accurate or complete as there may be several other standards available and therefore comments femua welcome.
Material standards and committees for the international oil & gas
Paint and colour industries Pipes of requirement class A EN —2: Petroleum and related technologies The benefits of standardisation, such as cost reduction and a speedier distribution of products can be expected. We collate and distil this valuable knowledge for the industry to use as guidelines for good practice by individual members. This eemau is still in its development stages, with DIS ballot closed in November of Resistance butt and flash welding ISO —1 Qualification testing of welders eemha underwater welding — Part 1:
