NF ISO 5597

Le présent document est destiné à faciliter l'interchangeabilité dimensionnelle des joints d'étanchéité pour tiges de piston et pistons de vérins hydrauliques. Pour cela, il fixe les dimensions et les tolérances des logements auxquelles doivent se conformer les fabricants de joints.

<p>ISO 5597:2010 establishes the preferred range of nominal dimensions and associated tolerances for a series of hydraulic cylinder rod and piston seal housings for reciprocating applications in the following range of dimensions: cylinders 16 mm to 500 mm and rods 6 mm to 360 mm.</p> <p>An additional range of seal housings is detailed in ISO 5597:2010 to meet the reduced envelope requirements of the 160 bar (16 MPa) compact series of ISO 6020-2; these smaller section seals require stricter piston rod and cylinder bore tolerances. The range of dimensions are as follows: cylinders 25 mm to 200 mm and rods 12 mm to 140 mm.</p> <p>ISO 5597:2010 does not give details of seal design, since the manner of construction of seals varies with each manufacturer. The design and material of the seal and any incorporated anti-extrusion component are determined by conditions such as temperature and pressure.</p> <p>ISO 5597:2010 applies only to the dimensional criteria of products manufactured in conformity with ISO 5597:2010; it does not apply to their functional characteristics.</p>
