17、on of handle assem-blies having rotating fingergrips.5. Significance and Use5.1 These tests provide standard methods for evaluating themechanical performance of the rotary-type window operators,while the operators are subjected to cyclic wear in opening andclosing against the operating moment.6. App
18、aratus6.1 The apparatus described is general in nature and anyarrangement of equipment capable of performing the testprocedure within the allowable tolerances is permitted.6.2 Test Method A:6.2.1 The test apparatus for Test Method A shall consist ofa frame for mounting the rotary operator with the o
19、peratorarm(s) centered (approximately the center of travel); testweights up to 5 lbs (2280 g) accurate to within 61.0 % or testweights above 5 lbs (2280 g) accurate to within 60.5 %,attached by flexible cable to the arm(s) to provide the requiredtest forces; an attachment bolt fastening the cable to
20、 the arm; atorque-limiting clutch, whose output is within 615%ofthespecified closing torque, attached to the handle drive mecha-nism in line with the operator input shaft and driven by areversible motor; and limit switching devices to effect reversalof rotation at the fully open and fully closed ope
21、rator positions(see Fig. 1).6.2.2 The arm or the test attachment bolt through the armshall bear against the test frame, if necessary, to prevent thearm from closing beyond the nominal fully closed position.The cables shall be adjustable to provide an equal tension forcein both the cables when the te
22、st attachment point and pivot arecentered.6.2.3 Fig. 2 shows how, if a vertical arrangement were used,to test a single-arm operator, a system of two test weights, anupper weight equal to the test force, and a lower weight oftwice the test force would act to provide the required down-ward force when
23、the arm is above the center position of itstravel and the same force upward when the arm is below thecenter of its travel. For operators with two arms, sum of the testweight on each arm should equal the total test weight withneither arm seeing less than 25 % of the total test weight. Thetest weight
24、is to be divided proportionally to simulate theloading seen in actual use. Fig. 3 shows a typical handle drivefork used to operate the rotary operator. If it is impractical todrive certain operating handles through their grip portion, theymay be modified so that portion making the connection to theo
25、perator input shaft is used as part of the test operator.6.3 Test Method B:6.3.1 The test apparatus for Test Method B shall consist ofa motor, shaft, timer, test weight, and attaching collar. Thereversible motor drives a horizontal shaft to which the testhandle is attached. The shaft shall be obtain
26、ed by removing theinput shaft from an operator or as an additionally supplied part.The handle end of the shaft shall be identical to the input shaftsof the test operators. The timing device effects a reversal of themotor at required intervals. The split collar carries the testweight and attaches to
27、the rotating fingergrip of the handlecausing one revolution of the fingergrip with respect to thehandle for each revolution of the handle (see Fig. 4).7. Test Specimens7.1 The operator test specimens shall be representative in allrespects of the operators to be qualified under these testmethods. Unl
28、ess otherwise specified, the specimens shallconsist of six identical production samples of the completerotary operator, four of which shall be selected at random fortesting. The remaining two samples shall be identified and filedwith the four tested specimens as part of the retained sample.7.2 Handl
29、es shall be included in all test specimens. Whereseveral styles of handles are furnished to fit different models ofoperators having identical input shaft ends, handles tested onone model of operator shall be considered tested at that testoperating moment and closing torque on all models of opera-tor
30、s with identical shaft ends.8. Required Information From Specifying Authority8.1 The specifying authority shall provide the followinginformation:8.1.1 Identification of the test samples,FIG. 1 Typical Operator Test ApparatusE405 04 (2012)28.1.2 The required peak operating moment, in some fullmultipl
31、e of 10 lbfin. (1.1 Nm),8.1.3 The required closing torque, in some full multiple of 5lbfin. (0.55 Nm), and8.1.4 The number of test cycles required if no prior failureoccurs. (A minimum of 3500 cycles are recommended.)8.2 The authority requesting the operator testing shall pro-vide the test laborator
32、y with load distribution information forthe arms of two arm operators to be tested.NOTE 2Care must be exercised in providing the above information toensure the specified requirements are not in conflict with the specification,and that the required closing torque is compatible with the necessaryopera
33、ting torque. Since the torque-limiting clutch normally used toestablish the maximum closing torque during the test also establishes themaximum operating torque that can be applied to the window, theminimum value of closing torque that is practical is determined by thenecessary operating torque.9. Pr
34、ocedure9.1 Test Method AOperator:9.1.1 Select a practical output-arm length to allow applica-tion of the specified operating moment without causing diffi-culty in the design and operation of the test apparatus. Drill ahole in the output arm to provide an attachment location fortesting purposes. Note
35、 the output-arm length and method ofattachment in the test report.9.1.2 Install the rotary operator in the test frame at an angle,if necessary, with the arm perpendicular to the line of action ofthe test force when at the center of its travel. (If the operatorhas two arms, both arms are to be treate
36、d the same with thesum of the operating moments on each arm equal to the totalpeak operating torque specified.) Adjust the cables to providebalanced loads on the attachment bolt when the test attachmentpoint and pivot are on a line perpendicular to the line of actionof the test force. As the operato
37、r handle is turned to move thearm toward the fully closed position, the test weights willprovide an opposing test force until the arm is in its fully closedposition simulating the forces applied by a person tightlyclosing a window. Apply the torque for at least 0.25 s, not toexceed 5 s. Maintaining
38、the opposing test force, reverse thedrive motor causing the arm to move back to the centeredposition. As the arm continues to move toward the fully openposition, the test weights provide an opposing test force. Whenthe arm reaches its fully open position, reverse the drive motor,returning the arm to
39、 center. The operator input shaft rotationshall not exceed 50 r/min and shall be essentially uniform.(WarningCare must be exercised to ensure that there is notexcessive heating of the test sample due to friction at the highershaft rotation speeds. Excessive temperature rise can result inoperator per
40、formance degradation and an invalid test.)9.1.3 The number of cycles to be run if no prior failureoccurs shall be at the option of the specifier. The inability of theoperator to raise the test weights constitutes failure.9.2 Test Method BHandle with Rotating Fingergrip:9.2.1 Mount the operating hand
41、le on the motor-drivenhorizontal shaft simulating the input shaft. Attach a circumfer-ential collar to the operating handle centered along the rotatingfingergrip area. The handle test weight is calculated to apply amaximum torque to the operator shaft equal to the input torquerequired to develop the
42、 required peak-operating moment speci-fied in 8.1.2 for the rotary operator of which the handle is apart. Fix the test-weight cable to the collar to cause one rotationof the fingergrip, in relation to the handle, for each rotation ofthe handle. Stop the shaft rotation and reverse the direction ofrot
43、ation at least once each minute. The shaft rotation shall notexceed 50 r/min and shall be essentially uniform.9.2.2 If no prior failure occurs, stop the test when thenumber of cycles specified for the operator is reached. Theinability of the handle to raise the weight, or the failure of therotating
44、fingergrip to rotate, or both, constitutes failure.FIG. 2 Force on Operator ArmFIG. 3 Typical Handle Drive ForkFIG. 4 Typical Handle Test ApparatusE405 04 (2012)310.
