IS 15309 : 2025/ISO 8518 : 2022 Workplace Air - Determination of Particulate Lead and Lead Compounds - Flame or Electrothermal Atomic Absorption Spectrometric Method
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical to ISO 8518 : 2022 'Workplace air - Determination of particulate lead and lead compounds - Flame and electrothermal atomic absorption spectrometric methods' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Air Quality Sectional Committee and approval of the Chemical Division Council.
The health of workers in many industries, for example, mining, metal refining, battery manufacture, construction, is at risk through exposure by inhalation of particulate lead and lead compounds. Industrial hygienists and other public health professionals need to determine the effectiveness of measures taken to control workers' exposure, and this is generally achieved by making workplace air measurements.
This standard was first published in 2003 as an identical adoption of ISO 8518 : 2001 under dual numbering. This revision has been brought out in order to align it with the latest version of ISO 8518 : 2022. In this revision following modifications have been done:
a) A new Annex B (informative) has been added concerning sampler wall deposits;
b) References and definitions have been updated; and
c) Additional editorial changes have been made.
This standard specifies flame and electrothermal atomic absorption spectrometric methods for the determination of the time-weighted average mass concentration of particulate lead and lead compounds in workplace air.
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker in the International Standard, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
