Formerly under the jurisdiction of Committee F29 on Anesthetic and Respiratory Equipment, this specification was withdrawn in January 2008 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
1.1 This specification covers critical dimensions and considerations for the junction of any blade and any handle of a hook-on type laryngoscope to allow engagement, lamp illumination, and disengagement through multiple cycles. An electrical lamp is fixed to the blade and supplied with energy through the handle.
1.2 This standard does not cover: (1) the blade form or handle design beyond the interchangeability aspects of the connection between the blade and the handle; (2) the measurement and specificiation of the lamp illumination intensity; and (3) disposable, flexible, and fiber-illuminated laryngoscopes designed for surgery.
1.3 The state-of-the-art of laryngoscope performance does not permit sufficient reproducibility to allow inclusion of mandatory force values in this standard; therefore, only recommended values have been provided.
1.4 The values stated in SI units are to be regarded as the standard. The values stated in inch-pound units may be approximate.
