3 Dimensions
3.1 General
Symbols and designations of dimensions are specified in ISO 14588.
3.2 Rivet dimensions
See Figure 1 and Table 1.
3.3 Clearance hole diameters
The diameters of the clearance holes (dh1) to accommodate the rivet in the components to be fastened are given in Table 2.
Non-conformance to the values listed in Table 2 may result in assembly difficulties and/or reduction in the shear and tensile loads specified in Table 3.
When necessary to facilitate alignment, only the component on the access side may have a clearance hole larger than specified in Table 2 (see Figure 2). This may also result in a reduction of the shear and tensile loads specified in Table 3.
4 Material and finish
Blind rivets in accordance with this International Standard shall have a rivet body made of steel (St) and a mandrel made of steel (St) and shall have mechanical properties as specified in clause 5.
Material specification is at the discretion of the manufacturer.
The surface of rivet body and mandrel shall be zinc plated 5 um minimum in accordance with ISO 4042 measured at the rivet head.
The chromate conversion coating shall be c2C in accordance with ISO 4520:1981.
The complete finish designation is then Fe/Zn5c2C.BS EN ISO 15976 pdf download.
