1.1 These test methods cover the determination of the resistance of dried varnish films to immersion in water and dilute alkali at room temperature.1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.1.3 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.

5.1 Although this practice is intended for the collection of dried paint samples in and around buildings for the subsequent determination of lead content, this practice may also be used to collect paint samples from other structures for lead analysis.35.2 The variability associated with the sampling of dried paint is generally considered to be far higher than the variability associated with the analyses of the paint specimens. Therefore, it is essential that sample collection be properly controlled to produce representative and meaningful samples.5.3 These samples are collected in a manner that will permit subsequent digestion using sample preparation techniques such as Practices E1645 or E1979 and determination of lead using laboratory analysis techniques such as inductively coupled plasma atomic emission spectrometry (ICP-AES) (see Test Method E3203) or flame atomic absorption spectrometry (FAAS) (see Test Method E3193).1.1 This practice covers the collection of samples of dried paint and other coatings from buildings.1.2 This practice is used to collect samples for subsequent determination of lead on an area basis (milligrams of lead per area sampled) or concentration basis (milligrams of lead per gram of dried paint collected or mass percent of lead in the paint sample collected).1.3 This practice does not address the sampling design criteria (that is, sampling plan that includes the number and location of samples) that are used for risk assessment and other lead hazard activities. See Guide E2115 or Practices E2271/E2271M or E3074/E3074M.1.4 This practice contains notes that are explanatory and are not part of the mandatory requirements of this practice.1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.6 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. A specific warning statement is given in 7.4.1.1.1.7 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.

4.1 The permissible level of heavy metals in certain coatings is specified by governmental regulatory agencies. This test method provides a fully documented procedure for determining low concentrations of lead present in both water and solvent-reducible coatings to determine compliance.1.1 This test method is intended as a screening test to determine if the solids in a paint contain more than 0.5 % lead. The test described barely detects the presence of 0.4 % but gives a definite positive result at the 0.5 % level.NOTE 1: This test method may be used to detect the presence of lead at concentrations higher or lower than 0.5 % by making appropriate changes in the specimen size and reagent quantities specified.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 Paints giving an unexpected positive or questionable result should be analyzed quantitatively for lead, using Test Method D3335.1.4 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. Specific hazard statements are given in Section 7.1.5 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.

5.1 This test method is intended for use with other standards that address the collection and preparation of samples (dusts by wipe, dried paint chips, and soils) that are obtained during the assessment or mitigation of lead hazards from buildings and related structures.5.2 Laboratories analyzing samples obtained during the assessment or mitigation of lead hazards from buildings and related structures shall conform to Practice E1583, or shall be recognized for lead analysis as promulgated by authorities having jurisdiction, or both.NOTE 1: In the United States of America, laboratories performing analysis of samples collected during lead-based paint activities are required to be accredited to ISO/IEC 17025 and to other requirements promulgated by the Environmental Protection Agency (EPA).5.3 This test method may also be used to analyze similar samples from other environments such as toxic characteristic extracts of waste sampled using Guide E1908 as prepared for analysis using EPA SW-846 Test Method 1311.1.1 This test method specifies a procedure for analysis of dried paint, soil, and dust wipe samples collected in and around buildings and related structures for lead content using inductively coupled plasma-optical emission spectroscopy (ICP-OES).1.2 This test method should be used by analysts experienced in the use of ICP-OES, the interpretation of spectral and matrix interferences, and procedures for their correction. For determination of lead (Pb) and other metals in air by ICP-OES, see Test Method D7035.1.3 This test method cites specific methods for preparing test solutions of dried paint, soil, and wipe samples for analysis.1.4 It is the user’s responsibility to ensure the validity of this test method for sampling materials of untested matrices.1.5 No detailed operating instructions are provided because of differences among various makes and models of suitable ICP-OES instruments. Instead, the analyst shall follow the instructions provided by the manufacturer of the particular instrument. This test method does not address comparative accuracy of different devices or the precision between instruments of the same make and model.1.6 This test method contains notes that are explanatory and are not part of the mandatory requirements of this test method.1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7.1 Exception—The inch-pound and SI units shown for wipe sampling data are to be individually regarded as standard for wipe sampling data.1.8 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.1.9 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.
