ASTM E1216-99(2005)

Standard Practice for Sampling for Particulate Contamination by Tape Lift

SCOPE
1.1 This practice provides a procedure for sampling surfaces to determine the presence of particulate contamination, 5 [mu]m and larger. The practice consists of the application of a pressure sensitive tape to the surface followed by the removal of particulate contamination with the removal of the tape. The tape with the adhering particles are then mounted on etched counting slides. Counting and measuring of particles is done by standard techniques.
1.2 This practice describes the materials and equipment required to perform sampling of surfaces for particle counting and sizing.
1.3 The criteria for acceptance or rejection of a part for conformance to surface cleanliness level requirements shall be determined by the user and are not included in this practice.
1.4 This practice is for use on surfaces that are not damaged by the application and removal of adhesive tape. The use of this practice on any surface of any material not previously tested or for which the susceptibility to damage is unknown is not recommended. In general, metals, metal platings, and oxide coatings will not be damaged. Application to painted, vapor deposited, and optical coatings should be evaluated prior to implementing this test.
1.5 This standard does not purport to address all of the safety problems, 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.
