The values above are intended
to act as a guide only to the primary selection of materials and should
not be used for specifications. Tests above conducted generally on "sheet
material" in accordance with ASTM and JIS methods.
Ultimate compressive strengths of CDS tube materials are typically
lower than sheet materials :.
