Gas cylinders - Design, construction and testing of refillable seamless steel gas cylinders and tubes - Part 2 : quenched and tempered steel cylinders and tubes with tensile strength greater than or equal to 1 100 MPa

This document specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes, examination and testing at time of manufacture for refillable seamless steel gas cylinders and tubes with water capacities up to and including 450 l. it is applicable to cylinders and tubes for compressed, liquefied and dissolved gases and for quenched and tempered steel cylinders and tubes with an actual tensile strength Rma ≥ 1 100 MPa. It is not applicable to cylinders and tubes with Rma, max > 1 300 MPa for diameters >140 mm and guaranteed wall thicknesses a′ ≥ 12 mm and for cylinders and tubes with Rma, max > 1 400 MPa for diameters ≤140 mm and guaranteed wall thicknesses a′ ≥ 6 mm because, beyond these limits, additional requirements can apply.

Le présent document prescrit les exigences minimales concernant le matériau, la conception, la construction et la mise en oeuvre, les modes de fabrication, les examens et les essais au moment de la fabrication des bouteilles à gaz rechargeables, en acier trempé et revenu sans soudure, d'une capacité en eau comprise entre 0,5 I et 150 I inclus, pour gaz comprimés, liquéfiés ou dissous. Il s'applique aux bouteilles ayant une résistance maximale à la traction Rma > ou = 1 100 MPa. Il ne couvre pas les bouteilles dont Rma, max > 1 300 MPa pour un diamètre > 140 mm et une épaisseur de paroi garantie a' > ou = 12 mm, et dont Rma, max > 1 400 MPa pour un diamètre < ou = 140 mm et une épaisseur de paroi garantie a' > ou = 6 mm ; en effet, au-delà de ces limites, des exigences supplémentaires peuvent s'appliquer.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
