Standard Practice for Measuring the Concentration of Toxic Gases or Vapors Using Detector Tubes
N D4490
Annotation
This practice covers the detection and measurement of concentrations of toxic gases or vapors using detector tubes (1, 2)2 A list of some of the gases and vapors that can be detected by this practice, their 1994–95 TLV values recommended by the ACGIH, and their measurement ranges are provided in Annex A1. This list is given as a guide and should be considered neither absolute nor complete.
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.
The boldface numbers in parentheses refer to the list of references at the end of this practice.

Утвержденный технологический процесс для измерения концентрации токсичных газов или паров Используя детекторные лампы
Эта практика покрывает обнаружение и измерение концентраций токсичных газов или паров с помощью труб детектора (1, 2) список на 2 А некоторых газов и паров, которые могут быть обнаружены этой практикой, их 1994–95 значений TLV, рекомендуемых ACGIH, и их диапазоны измерений обеспечиваются в Приложении A1. Этот список дают как руководство и нужно рассмотреть ни абсолютный, ни завершенный.
