1、Designation: F1093 99 (Reapproved 2012)Standard Test Methods forTensile Strength Characteristics of Oil Spill ResponseBoom1This standard is issued under the fixed designation F1093; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, t
2、he year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods cover static laboratory tests of thestrength of oil spill response boom under tensile lo
3、ading.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any
4、, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

Summary of Test Method4.1 A specimen of spill containment boom is tested bysubjecting the specimen to cyclic tests to 100 % of themanufacturers rated tensile stren
10、gth, and by applying tensileloading which progressively deforms the specimen to the pointof failure. Similarly, a typical anchor point and towing deviceare tested in an additional tensile test. For each phase of thetest, values of tensile load and deformation are observed andrecorded, and modes of f
11、ailure are described.5. Significance and Use5.1 Boom sections are frequently combined into assem-blages hundreds of meters in length prior to towing through thewater to a spill site. The friction of moving long boomassemblages through the water can impose high tensile stresseson boom segments near t
12、he tow vessel.5.2 Tensile forces are also set up in a boom when it is beingtowed in a sweeping mode. The magnitude of this tensile forcecan be related to the immersed depth of the boom, the length ofboom involved, the width of the bight formed by the twotowing vessels, and the speed of movement.NOTE
13、 1When the towing speed exceeds about 1 knot (0.5 m/s),substantial oil will be lost under the boom.1These test methods are under the jurisdiction of ASTM Committee F20 onHazardous Substances and Oil Spill Response and are the direct responsibility ofSubcommittee F20.11 on Control.Current edition app

Apparatus6.1 Load Application DeviceA suitable load applicationdevice, such as a hydraulic jack, shall be provided. The devicemust be capable of applying loads somewhat in excess of t
17、hepredicted failure load on the boom.6.2 TensiometerA tensiometer shall be selected whichwill encompass the range of values from no load up to themaximum boom tensile load which might reasonably beexpected prior to failure of the boom.6.3 End SupportsThe test bed provided shall have endsupports of s
18、ufficient strength and rigidity to resist significantdeformation under the maximum loads expected during testing.6.4 Towing Devices and ConnectorsAt least one of themanufacturers standard tow bridles or towing devices shall beused at the leading end of the boom specimen (where the loadis applied). A
19、 similar tow bridle or towing device shall be usedat the trailing end if the test apparatus is long enough.However, if it is not, the connector at the trailing end of thespecimen may be attached directly to a connector fixed to thatend support of the test apparatus. Suitable shackles, cables,chains,
20、 and so forth, shall be provided to connect the towingadapters to the test equipment, as diagrammed in Figs. 1-3.6.5 Gage PointsGage points shall be affixed to each endof the test specimen to facilitate measurement of elongationduring the course of the test.6.6 Elongation Measurement ScaleA suitable
21、 measuringdevice shall be provided so that elongation measurements maybe made periodically throughout the test. The device shall havea precision equal or better than11000 th the distance betweengage points (that is, 3 mm precision for 3 m gage pointseparation).6.7 Boom Specimens to be TestedEquipmen
22、t shall bearranged to apply tensile loading to a specimen consisting of atleast two complete boom segments of standard length assupplied by the manufacturer. Boom segments of less thanstandard length may be used for this test provided that thetension member length is proportional, the hinge area bet
