34、r PropertiesOther property requirements suchas volatility (for example, Test Method D6), thermal oxidativestability (for example, testing similar to Test Methods D 942 orD 3895), cone penetration (for example, Test Methods D 217),corrosion prevention (for example, Test Method D 1743), andthe like, s

35、hall be as agreed upon between the producer and thepurchaser.NOTE 1If Test Method D6is referenced, a test cycle of 22 h at 107C (225 F) is recommended in lieu of the 163 C (325 F) temperaturerequired by Test Method D6.11.

38、or in the cable filling process. However, thismay be a good test for quality control purposes.11.2 The purchaser (individual cable manufacture or other)shall specify any other expected temperature conformancerequirements (high and low) needed to assure compliance withsuch end-product requirements as
