in THE MAIN WALL
Are these likely to tell me if there is a oxygen-diffusion barrier in the tubing?

    Hi

    (ASTM) American Society for Testing and Materials) D380 and D471

    If rubber tubing for radiant heat has these markings, what does it actually tell me about the tube?

    ASTM markings

    D380 is the standards for rubber hose
    D471 is the standards for rubber tubing and the effects of fluids on the tubing.
