1.1 This practice covers criteria to be used in defining strategies for sampling nonvolatile and semi-volatile organic chemicals on surfaces for workplace health and safety monitoring. Guidance is also given for the use of direct reading techniques, such as colorimetric measurement.

1.2 Relevant laboratory analysis techniques, such as gas or liquid chromatography with (a) suitable detector(s), are referenced (see Table X1.1).

1.3 Guidance provided by this practice is intended for sampling of non-volatile and semi-volatile organic compounds on surfaces. Samples can be collected in a manner permitting the use of direct reading methods for site characterization (for example, colorimetric measurement, or a lateral flow immunochemical assay (LFIA)) or solvent extraction of the organic compound(s) of interest from the sampling media, with subsequent analysis using methods such as gas chromatography, mass spectrometry, or high-performance liquid chromatography.

1.4 Sampling for volatile organic chemicals (organic compounds with a saturation vapor pressure greater than 10⁻² kPa at 25 °C) is not within the scope of this practice.

1.5 Sampling to determine levels of the selected organic chemicals on the skin is not within the scope of this practice.

1.6 Sampling for airborne particulate matter is not within the scope of this practice. Guide E1370 provides information on air sampling strategies.

1.7 Where surface sampling is prescribed by law or regulation, this practice is not intended to take the place of any requirements that may be specified in such laws or regulations.

1.8 This practice does not address the sampling design criteria (that is, a sampling plan which includes the number and location of samples) that are used for hazard evaluation, exposure assessment, risk assessment, clearance, and other purposes. To provide for valid conclusions, sufficient numbers of samples shall be obtained as directed by a sampling plan, for example as described in Guide D7659.

1.9 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.10 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
