“The conditions and test requirements described in Explosives Circular
  No. 1, issued under date of May 15, 1909, have been followed in all
  subsequent tests.

  “Subject to the provisions named below, a permissible explosive is
  defined as an explosive which is in such condition that the chemical
  and physical tests do not show any unfavorable results; which has
  passed gas and dust gallery tests Nos. 1 and 3, as described in
  circular No. 1; and of which, in test No. 4, 1½ pounds (680 grams) has
  been fired into the mixture there described without causing ignition.
