Why devote a separate chapter to a specific type of asbestos-containing materials? Why was ASTM E2394 Standard Practice for Maintenance, Renovation and Repair of Installed Asbestos Cement Products written for these materials? Because asbestos-cement has been one of major uses of asbestos fiber worldwide and remains a global market for nearly all of the fiber still produced. Its health effects will haunt mankind for decades to come (see Chapter 1, “The Foundations of Asbestos Management”).
