Description

1.1 This International 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.
1.2 The method is applicable to personal sampling of the inhalable fraction of airborne particles, as defined in
ISO 7708, and to static (area) sampling.
1.3 The sample dissolution procedure specifies hot plate or microwave digestion, or ultrasonic extraction (11.2).
The use of an alternative, more vigorous dissolution procedure is necessary when it is desired to extract lead from
compounds present in the test atmosphere that are insoluble using the dissolution procedures described herein.
1.4 The flame atomic absorption method is applicable to the determination of masses of approximately to of lead per sample, without dilution [1]. The electrothermal atomic absorption method is applicable to the determination of masses of approximately to of lead per sample, without dilution [1].
1.5 The ultrasonic extraction procedure has been validated for the determination of masses of approximately
to of lead per sample, for laboratory-generated lead fume air filter samples [2].
1.6 The concentration range for lead in air for which this procedure is applicable is determined in part by the sampling procedure selected by the user (see 10.1).

IMPARTIALITY AND CONFIDENTIALITY STATEMENT
The Botswana Bureau of Standards (BOBS) understands the importance of impartiality and confidentiality in carrying out its management system certification activities. BOBS management is committed to gaining and maintaining the reputation, credibility and ultimately, confidence of its stakeholders in rendering its certification services. Additionally, BOBS strives to continuously manage foreseen potential conflicts of duty and interest and ensures objectivity of its activities under the management system certification. To achieve the above, BOBS shall identify, analyse, record and manage potential conflict of duty and interest to ensure that certification services are not provided within relationships that have been identified to pose an unacceptable threat to impartiality. An Impartiality Committee shall periodically review activities of the certification function to verify commitment to credibility and fairness. The Committee shall further assist in the development of policies relating to impartiality of providing certification activities. BOBS is committed to maintaining in strict confidence all information accessed while rendering the certification services and shall ensure that such information is not divulged to third parties without the Client’s written consent unless if required by law.

When things don't work as they should, it often means that standards are absent.
