ASTM B299/B299M-18

1.1 This specification covers the purchase of virgin titanium sponge metal. This virgin metal is commonly designated as titanium sponge because it is most commonly porous and sponge-like in texture, although metal produced electrolytically is granular and is essentially nonporous.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
