1、Designation: F2684/F2684M 07 (Reapproved 2012)1Standard Test Method forPortable High Anchor Devices1This standard is issued under the fixed designation F2684/F2684M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last

2、revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in August 2012.1. Scope1.1 This test method applies to portable high anchor devicestha

3、t may be used by rescue personnel during both trainingexercises and actual rescue operations.1.2 This test method covers two mechanical tests, the StaticLoad Test and the Load Test for Failure.1.3 Tests contained herein are destructive in nature. Portablehigh anchor devices subjected to any of these

4、 tests shall not beused in any way after testing except in evaluating the results ofsuch testing.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used in

5、dependently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.5 This specification does not imply approval of anymethod of use of portable high anchor devices. In addition, thetests described are laboratory tests and do not duplicate fieldconditions.

6、 Furthermore, the test load values contained hereinare not to be interpreted as the forces which a portable highanchor device may be subjected to, or may be expected tosustain, in actual field use.1.6 See Section 6 on Hazards for safety warning.2.

8、 cantile-vered devices.4. Significance and Use4.1 Static Load TestThis test verifies that the portablehigh anchor device can support the design load withoutpermanent deformation and continue to function in a safemanner.4.2 Load Test for FailureThis test determines the force atwhich the portable high

9、 anchor device fails.5. Apparatus5.1 For both tests, the portable high anchor device shall bepositioned on a flat concrete surface in the manner described bythe manufacturers instructions for use.5.1.1 Where portable high anchor devices are designed to beaffixed to a base or structural member that i

10、s not part of thedevice, the manufacturer shall provide a test base that mostclosely resembles the structural element to which the device isdesigned to be affixed. This test base shall be completely stableand shall be permitted to be bolted down to prevent movementduring the test.5.1.2 Portable high

11、 anchors designed to be attached toflanged rims of vessel openings would require a test base tosimulate the flanged portal to which the device is designed tobe affixed.5.1.3 Portable high anchors such as beam clamps that aredesigned to be attached to a structural element would require acompatible se

12、ction of the beam to which the device is designedto be affixed.6. Hazards6.1 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine

13、the applicabil-ity of regulatory limitations prior to use.1This test method is under the jurisdiction of ASTM Committee F32 on Searchand Rescue and is the direct responsibility of Subcommittee F32.01 on Equipment,Testing, and Maintenance.Current edition approved June 15, 2012.

Sampling, Test Specimens, and Test Units7.1 Two samples of each model of portable high anchordevice shall be required.7.1.1 Samples of each model of each portable high anchordevice shall be selected randomly for testing.7.1.2 Test samples s

16、hall be new and in an unused conditionand shall conform in all respects to the manufacturers speci-fications for the model to be tested.8. Procedure8.1 Testing Set-Up8.1.1 The device shall be positioned according to manufac-turers instructions with all surface contact points securelyseated before te

17、sting.8.1.2 The device shall not be bolted, tied off, or affixed tothe test base in any way unless required by the manufacturerfor normal use.8.1.3 The device shall be positioned as required in thelowest strength configuration of the device as specified by themanufacturer.8.1.3.1 In most cases, the

18、portable high anchor device willbe weakest at its greatest (or highest) extension. However,many devices have multiple ways they can be used. Differentrigging configurations may be stronger or weaker than others.It is intended that the testing be done in the configurationspecified in the manufacturer

19、s instructions that would yieldthe lowest strength results.8.1.4 For all tests, the device shall be attached to the testmachine at the load-bearing connecting point, in accordancewith the manufacturers instructions for use, with a suitablelocking carabiner or other connector.8.1.5 For all tests, all

20、 adjuncts designed by the manufacturerto be used in conjunction with the device, including but notlimited to ropes, chains, webbing, rope grabs, and bolts, shallbe in place.8.1.6 Each point of contact with the test surface shall bemarked in some manner to allow the ability to measuremovement of the

21、base during the test.8.1.7 When testing davits or other cantilevered devices, theload-bearing connection point may move as the device deflects.Make provisions to keep the application of force verticalthoughout the test.8.1.7.1 For example, applying force with a hydraulic cylin-der attached to a trav

22、eler on an “I” beam secured to the testbase in line with the deflection.8.2 Static Load Test8.2.1 The Static Load Test shall be set up as specified in 8.1.8.2.2 A force shall be applied to the portable high anchordevice at a rate of 25 6 5 mm/min 1 6 0.2 in./min, increasingto a minimum load of at le

24、.2.5 At the conclusion of the Static Load Test described in8.2, the sample portable high anchor device shall be inspectedto determine pass/fail. A portable high anchor device shall beconsidered to fail if any of the following are observed:8.2.5.1 If any of the load-bearing members remain deflectedby

25、 more than 1 % of the length of the member from theiroriginal position.8.2.5.2 If there is any cracking or breaking visible to theunaided eye.8.2.5.3 If an adjustment or moving part becomes nonfunc-tional.8.2.5.4 If any base contact point deviates by more than 150mm 6 in. from its original position.

26、8.2.5.5 Where there are multiple load-bearing connectionpoints, the Static Load Test shall be repeated for each load-bearing connection point, or combination of load-bearingconnection points, specified in the manufacturers instructions.8.3 Load Test for Failure8.3.1 The Load Test for Failure shall b
