The product may be subject to pronounced dynamic loading in addition to high static loading.

Welding Fabrication Standards Page 41 Manufacture can be complex and the range of materials could include high performance metals as well as more standard materials such as structural boiler steels and aluminium alloys that require enhanced controls to avoid the occurrence of deleterious fabrication imperfections. 3.3.2 ISO 3834-3 - Standard quality level This part can be applied to constructions in which failure of welds could impair the intended use of the construction and the operational unit in which it forms a part. The product would have a normal safety risk and the financial consequences would not be extreme. The manufacturing technique would be conventional without reliance on high performance materials and the production processes would be well established. 3.3.3 ISO 3834-4 - Elementary quality level This part can be applied to constructions in which failure of welds would not fundamentally impair the intended use of the constructions. Additionally, failure would not be expected to have any adverse effects on the safety of people and would only have minor financial consequences. The materials used would be simple as well as the manufacturing technique. Istituto Italiano della Saldatura Lungobisagno Istria, 15 - 16141 Genova (I) - Tel. 01083411 - Fax 0108367780
