ISO.4759-1,Tolerances for fasteners-Part 1: Bolts, screws, studs and nuts-Product grades A, B and CISO.6947,Welding and allied processes – Welding positions.
3.Terms and definitions:No terms and definitions are listed in this document.
4.1 Ordering information
At the time of order, the manufacturer shall obtain the following information:a) a reference to this document if the purchaser demands compliance;
b) quantities to be delivered;
c complete product designation;
d) other requirements as agreed with the purchaser (e.g.low-temperature requirements)
4.2 Dangerous substances:Materials used in products shall not release any dangerous substances in excess of the maximum levelspermitted in the relevant regulations of the state of destination.
4.3 Product requirements
4.3.1 Dimensions and tolerances on dimensions, form and position
Dimensions and tolerances on dimensions form and position shall be in accordance with therequirements given in Clause 6.
For coated threaded studs, the tolerances shall apply before coating.
Studs shall be free of defects which can affect the application.
4.3.2 Coating:Unless otherwise specified, studs PS, US, IS, PT, UT, IT of property class 4.8 shall be supplied withelectroplated copper coating(C1E).
4.3.3 Materials and mechanical characteristics General.The materials listed in Table 2 shall be used, under the provisions of 5.3.4.
The mechanical characteristics of the studs shall comply with the specifications in Table 2.Studs may consist of two different materials combined by friction welding (dual-material stud).NOTE The welding part corresponds to the parent metal to avoid problems with dissimilar materials infusion welding, the restgenerally consists of high alloy steel for enhanced corrosion resistance. Shear strength:Shear strength shall be checked by testing the minimum tensile strength of the studs.BS EN ISO 13918 pdf download.
