The task group agreed to eliminate the requirement for measurement of Ash content for the consolidated forms of UHMWPE (in Table 2), because it is already required to be measured on the powder (Table 1). Nothing is added to the powder during molding that could affect the amount of ash. The requirements for extraneous matter and incompete consolitation continue to be relevant and are unaffected by this proposed revision.
