Conditions4.1 Test is to be performed at ambient 20 C (68 F) conditions.4.2 Friction between the se
7、gment fingers and the clamp should be kept to a minimum (see 5.2.2).5. Test5.1 Equipment Set-up5.1.1 The three segments should be arranged to form the test diameter. This test diameter will be defined as acircle tangent to the apex of each radius.5.1.2 The test diameter will be the nominal clamping

9、d Test5.3.1 Clamp is to be installed and oriented as shown in Figure 1. SAE Type E and CTW clamps should beinstalled in a similar fashion to the CTB clamp depicted.5.3.2 The clamping force shall be defined as the average of the forces detected by each load cell.PREPARED BY THE SAE HOSE CLAMP COMMITT
