  • Page 3: Introduction

    ASTM F2970 Consumer Trampolines ASTM F381 To promote effective use a Triax 2015 system must be properly configured and used by a properly trained operator. The designation “E” and “A” refer to the different missile shape and corresponding support mechanism, and are described in ASTM F355. The “E” missile is hemispherical with a weight of 10.1 pounds and is supported by an adjustable height tripod.

  • Page 4: System Components

    The Triax2015 “E” system consists of the Triax2015 hand held controller, a hemispherical missile and a support tripod. Also included with the Triax 2015 “E” system are an 8” x 8” rubber reference pad, battery charger, manual drop handle and fitted carrying cases.
  • Page 5 Hydride (NiMH) batteries are of a lower power density than Lithium Ion batteries thus allowing the Triax system components to be transported by aircraft if required. Typical battery life on a full charge exceeds two months of substantial daily use.

  • Page 6: Hand Held Unit

    3.0 HAND HELD UNIT The hand held unit is shown in Photo 1. The main parts of the hand held are the eight key membrane keypad, the liquid crystal display (LCD), the lower cover and the memory card. Photo 1 - Triax2015 Hand Held with lower cover opened showing memory card and battery charger connection 3.1 Key Switch Functions 1.
  • Page 7 7. LAST – Allows the user to step through the drop test results, in descending order. Using the Memory Card the Triax can record up to 100 drop test in each of 10 folders for a total of 1000 drop tests (root directory plus 9 folders.) Drops are labeled 1 through 100 and only the drop tests stored in the currently selected folder are available for display (see Appendix C for information on changing folders).

  • Page 8: E" Missile

    The Triax2015 hand held and missiles each make use of permanent internal rechargeable nickel metal hydride (NiMH) batteries. Each Triax 2015 system is supplied with a battery charger with technology matched to the NiMH batteries used. The batteries in both the hand held and missile requiring charging independently.
  • Page 9 To prevent damage to the Triax 2015 missiles they should not be used in rain or snow. The Triax 2015 missiles should also be stored in dry locations such as a heated office. Storage of the Triax 2015 missiles in damp locations such as basements and cellars must be avoided.

  • Page 10: Tripod

    5.0 Tripod The Triax2015 Tripod is shown in Photo 3. In addition to the three leg section attached to the top of the tripod, nine snap together sections of legs are provided with the Tripod to allow a maximum drop height of up to approximately 12 feet (drop height is measured from the bottom of the missile to the top of the surface to be tested.) Photo 3 - Tripod with Head Form and Reference Pad...
  • Page 11 CAUTION! Erecting the tripod can be a hazard due to tipping. To erect the tripod, two persons are recommended. Use of proper head protection is also suggested, as the operating height of the tripod will, in most cases, be above the head of the operators exposing them to the hazard of being struck by either the head form or the tripod.
  • Page 12 Photo 5A – Properly connected leg section with pin fully extended Photo 5B – INCORRECT connection – pin not fully extended Three of the nine leg sections feature a rounded end. These must always be installed as the lowest leg sections when the Tripod is erected. Whenever connecting leg sections the Tripod must first be laid on a horizontal surface.
  • Page 13 Standing to the side the surveyor’s rod (supplied with every Triax 2015 E missile system) is used to verify the height of the missile. Fine height adjust can be made by holding the locking device while loosening the lock screw.
  • Page 14 5.4 Manual Drop Handle Preliminary testing without setup of the tripod can be conducted using the optional hand held drop handle. The use of the drop handle is shown in photo 6. When using the handle leave the release mechanism set to magnet (see Appendix B.3) Photo 6 –...

    6.1.5 Press the START key. A message will appear on the display indicating that the Triax 2015 is being prepared for the drop test. The first time the Triax 2015 is turned on after being turned off (or automatically turning itself off) approximately 12 seconds will be required for the Triax 2015 to become ready and display “READY FOR TEST”.
  • Page 16 Care must be taken to avoid injury from being struck by the rebounding missile. The user may optionally configure the Triax 2015 to display the HIC interval which the Triax 2015 display calls “Delta” Delta refers to the difference in milliseconds (or delta) between the t1 and t2 integration limits of the HIC interval.

  • Page 17: Report Generation Pc Application

    7.1 Installation The application is provided in the USERDOCS folder located on the Memory Card supplied with the Triax 2015. It is suggested that this folder be copied to the user’s PC, and an archival copy also be created. Install the Triax2015 host application on a Windows compatible platform by running the SETUP.EXE program supplied in the \USERDOCS\HOST folder.
  • Page 18 menu option, and then click Select Drops for Upload. A box will appear allowing the selection of which drops to upload. If it is unknown which drop numbers have been data select all 100 drops. The application will attempt to load all 100 drops but will ignore drops for which there is no data.
  • Page 19 .DRP file so as to prevent confusion for the user during subsequent testing. The .DRP files do not need to be erased as the Triax 2015 hand held controller will overwrite old drop test files with new drop test files.
  • Page 20 7.3 Adding individual comments to each drop The report application allows comments to be added for each drop. Typical uses for comments would be to indicate the location on the surface the drop test was made or any observation particular to the specific drop. To add or edit a comment, click once on the desired drop and then hit the ENTER key.
  • Page 21 7.4 Adding a report comment To add or edit a single comment to summarize all the drops within a report, double click on the text box immediately below the menu bar. A text box will appear allowing the adding of a new report comment or editing of an existing report comment. Press the ENTER key when complete.
  • Page 22 7.5 Viewing Impact Waveforms (Graphs) To view the impact waveform, double click on the desired drop test. 7.6 Archiving Data To archive test data, select Save to Data File under the File menu option. A text box will appear prompting for a file name to which all drop tests currently displayed will be saved as a single file.
  • Page 23 NOTE: The HIC Interval is a mathematically sophisticated technical detail regarding how the HIC was calculated for a given drop. Some new standards are using the HIC Interval as an added pass / fail criteria but it has not yet found wide use. Most users will want to leave the HIC Interval setting left to HIDE to prevent confusion.
  • Page 24 7.9 Calculation of Critical Fall Height – EN1177 Method For critical fall height (CFH) calculation as per EN1177 four drop tests must be performed, changing the drop height to result in increasing HIC values. The first two drop tests must result in HIC values below 1000 while the second two result in HIC values greater than 1000.

    36” +/- ¼” (915mm +/- 5mm) above the surface of the reference mat. For a Triax 2015 “A” missile system the drop height is 24” +/- ¼”, and is measured from the surface to the center of the release knob.
  • Page 26 Triax 2015 calibration interval is extended to two years. Users may elect to calibrate their instruments on the tradition one year (or shorter) interval as may be required by their respective quality or other policies.

    Files and folders can be copied, deleted and created using standard PC applications such as Windows Explorer. The Triax 2015 allows the user to store drop results in one of ten folders on memory card. When a new memory card without any folders is installed in the Triax 2015 drop test results will be stored in the ROOT folder (the folder is not actually called ROOT.
