Nichiproducts Nichipanel has a lapsed listing for 5/16-inch fiber-cement boards.
Its historical ignition-resistant-material entry needs current confirmation before it can support a specification.
OSFM's 8170-2029:0007 entry names Nichipanel in the Nichiproducts series and identifies ASTM E84 with an extended 20-minute test. The thickness belongs to the named board. The description refers construction details to Nichiha's installation instructions and product data sheets rather than supplying a wall backing or fastening schedule.
Nichipanel appeared in the September 2025 handbook but was missing from the BML check on August 25, 2026. Its absence leaves expiration, withdrawal and renumbering as unresolved possibilities. An installer therefore needs the exact current listing and manufacturer construction documents, with the Nichipanel model and board thickness carried into that check. The historical test label does not settle whether this listing remains available for use.
