EN ISO 1179-2:2013 PDF

Scope: This part of ISO 1179 specifies dimensions, performance requirements and test methods for heavy series (S series) and light series (L series) threaded studs in accordance with ISO 228-1 and elastomeric seal (Form E). Heavy series (S series) male studs with form E seal conforming to this part of ISO 1179 can be used at working pressures up to 63 MPa (630 bar). Light series (L series) male studs with form E seal conforming to this part of ISO 1179 may be used at working pressures up to 25 MPa (250 bar). The permissible working pressure depends on the size, materials, construction, operating conditions, application, etc. Compliance with the dimensional specifications in this part of ISO 1179 does not guarantee rated performance. It is the responsibility of each manufacturer to carry out tests as specified in this part of ISO 1179 to ensure that components manufactured in accordance with this part of ISO 1179 conform to the rated performance. NOTE 1 This part of ISO 1179 applies to fittings conforming to ISO 8434-1 and ISO 8434-2. NOTE 2 The introduction to this part of ISO 1179 contains recommendations for screw holes and tenons for new designs in hydraulic and pneumatic power transmission systems.
