Designation:F96204(Reapproved 2018)Standard Specification forOil Spill Response Boom Connection:Z-Connector1This standard is issued under the fixed designation F962;the number immediately following the designation indicates the year of originaladoption or,in the case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers design criteria requirements,design geometry,material characteristics,and desirable fea-tures for oil spill response boom connections.These criteria areintended to define minimum mating characteristics and are notintended to be restrictive to a specific configuration.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 international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2F818 Terminology Relating to Spill Response Booms andBarriersF1523 Guide for Selection of Booms in Accordance WithWater Body Classifications3.Material Characteristics3.1 End connector and cross pin materials shall be corrosionresistant in sea water and such other environments as theintended service may require.If dissimilar metals are used,care shall be used in design to avoid galvanic corrosion.3.2 Any material is acceptable for construction of the boomconnector provided consideration is given to such factors asweight,mechanical strength,chemical resistance,flexibility,and conditions of the environment in which it is to be used.4.Design Requirements4.1 The minimum tensile strength of a boom-to-boomconnection shall equal or exceed the minimum fabric tensilestrength specified in Table 1 of Guide F1523.4.2 When the connector is designed as an integral part of theboom,it shall ensure distribution or transfer of the tensionmember loads from one boom section to the next through oraround the end connector in such a manner that the integrity ofthe joint is not broken.4.3 The connector or adapter shall not take more than 0.04in.permanent set when a 250-lb load,distributed over 3 in.,isapplied.The load shall be applied at the location that results inmaximum deflection and shall be resisted by supports placed12in.from each end as shown in Fig.1.4.4 In addition to the dimensional requirements shown inFig.2,the self-locking cross-pin/lanyard assembly shall havethe following characteristics:4.4.1 Its assembled strength shall resist a tensile load of 180lbs placed upon the closed toggle by the test fixture to whichthe cross pins lanyard is attached without deformation asshown in Fig.3.4.4.2 It shall have a ring or lanyard loop of a minimumdiameter of 1-12in.for the convenience of pulling the pin fromthe boom connectors.4.4.3 The toggle shall turn freely and shall latch in eitherdirection.4.4.4 The cross-pins spring shall be captured or locked tothe assembly and shall exert a force on the toggle of between16 and 22 lbs when connectors are assembled.4.4.5 When the cross-pins spring is compressed fully,thereshall be a clearance of18in.between the short end of the toggleand the mated connector as shown in Fig.2.4.4.6 The cross-pins overall length shall be minimized andits ends rounded or chamfered so as to minimize wear and tearon adjacent stored booms or injury to boom handlers.4.5 Pinholes,designed to accommodate the38in.diameterself-locking pin,shall be incorporated at the design water line(DWL)and,if required,a location as determined in 4.5.1 or4.5.2 and shown in Fig.4.4.5.1 For any connector with 7.0 to 12.9 in.of connectormaterial below the DWL pinhole,a second pinhole shall belocated 6.000 6 0.0015 in.below the DWL pinhole as shownin Fig.4(a).1This specification is under the jurisdiction of ASTM Committee F20 onHazardous Substances and Oil Spill Response and is the direct responsibility ofSubcommittee F20.11 on Control.Current edition approved Nov.15,2018.Published December 2018.Originallyapproved in 1986.Last previous edition approved in 2010 as F962 04(2010).DOI:10.1520/F0962-04R18.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of Internati
