Note 1--A complete metric companion to Specification B111has been developed -- B111M; therefore no metric equivalents are presented in this specification.

Note 2--Warning-- Mercury is a definite health hazard in use and disposal. (See 12.1.)

1.2 The following safety hazards caveat pertains only to the test methods portion, Section 18, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
