  • Stock PVC and Other Materials Division

    Certain things are clear: PVC division requires the frame materials to be of only PVC, CPVC, Pex, etc.

    How about some of the more gray area components?

    I assume these are allowed in Stock PVC:
    - Zip ties
    - Tape like electrical tape or duct tape
    - Glues like superglue or hot glue
    - Electrical connectors/insulators like heat shrink or liquid electrical tape

    I'm not sure on these items
    - Non-PVC material to build a hook to life challenge elements like a pencil, chopstick, wire, etc
    - Non-PVC material for something to coral the floating challenge elements
    - Different motor waterproofing items like a different type of wax, etc

    And only pool noodle material can be used for flotation?

    brian_c The class information has been updated to clarify these areas.
    Please see the matrix and PDF document at https://www.seaperch.org/2020challenge.
    "Attachments and non-frame parts made from various materials but may not include 3D printed or additive manufactured parts."
    Yes, all the items you listed are allowed in the Stock PVC class.

      “Additive manufactured parts” does this mean something premanufactured and purchased? Understand not buying a gripper but if they use a syringe for hydraulics and make a gripper themselves is that okay for the PVC class? Also is is laser cutting flat materials for auxiliaries or attachments allowed in the PVC class? Thanks.

        Shanklincj Buying parts and modifying is allowed in PVC Class. Laser cutting or other fabrication technologies that use automated machinery is not allowed in the PVC class.

          Last question, are there any restrictions on the pvc pipe size? Specifically diameter.

              In regards to flotation, is the pool noodle the only material that can be used?

                The flotation may be any material as long as it not 3D printed as follows the other guidelines.
