    (What is a Work Item?)

    Active Standard: C1293 - 20a

    Rationale

    Section 5.2.2 - Alternative Containers allows for the use of containers other than those prescribed in Section 5.2.1 Recommended Container. Currently, the requirements for using alternative containers are inadequate and lack guidance or prescribed requirements to ensure the testing is being performed properly, such as: air tight lids, use of wicking materials, moisture loss requirements, etc. This work item aims to prohibit the use of alternative containers and only allow for the use of the recommend container.
