3.1.1 Finish. Components of hose clamps which are not made of inherently corrosion resistant materials shall be zinc plated and subjected to an embrittlement relief treatment.
3.2 Design, construction, and performance. Unless otherwise specified herein, the clamp design, construction, and performance of hose clamps shall be in accordance with SAE J1508. Clamp component parts shall remain as an assembly during installation and removal of the clamp.
3.2.1 Band length. The maximum overlap band length at the maximum of the hose diameter for type F, I, and M clamps shall be as specified in Figure 1 and shall be verified when subjected to salient characteristic. Metric measurements are noted in parenthesis (millimeter).
3.2.2 Clamping diameter verification. To verify the clamping diameter, the hose clamps shall be assembled over and closed tight upon round mandrels of diameters equal to the corresponding open and closed diameters specified in the dimensional tables in SAE J1508. Diameters smaller than closed diameters specified in SAE J1508 are allowable. Hose clamps shall meet the open diameter required with all threads engaged.
3.2.3 Torque. The hose clamp torque requirements shall conform to SAE J1508 for the appropriate type and size required.
3.2.4 Sealing capability. SAE J1610 shall be used to evaluate the pressure, vibration, and temperature (PVT) sealing capabilities of type F hose clamps.
3.3 Identification and marking. Unless otherwise specified (see 7.2), the hose clamps shall be identified or marked in a legible and permanent manner with the type, size, and manufacturer’s name or trademark. When required (see 7.2), the marking on small clamp sizes shall be placed on the outside of the box.
