5.1 Dirt, paper and mixtures of polymeric materials complicate the interpretation of data from procedures used to identify the contaminants in recycled plastics.1.1 This practice describes a procedure for separating recycled plastics based on their color and a procedure for washing dirty, ground plastic, which results in separation of light materials (density <1.00 g/cm3). This practice is not intended to represent generic washing procedures used in the plastics recycling industry. The described procedures are solely for preparation of plastic samples for use in other analytical tests. The procedure includes a room temperature wash step to facilitate separation of paper (for example, labels) followed by washing at an elevated temperature.NOTE 1: Although not presented as a quantitative method, the procedure presented in this practice may be used to provide quantitative results. The user assumes the responsibility to verify the reproducibility of quantitative results.1.2 The values stated in SI units are to be regarded as the standard.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.NOTE 2: There is no known ISO equivalent to this standard.1.4 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 Material finer than the 75-μm (No. 200) sieve can be separated from larger particles much more efficiently and completely by wet sieving than through the use of dry sieving. Therefore, when accurate determinations of material finer than 75 μm (No. 200) in fine or coarse aggregate are desired, this test method is used on the sample prior to dry sieving in accordance with Test Method C136/C136M. The results of this test method are included in the calculation in Test Method C136/C136M, and the total amount of material finer than 75 μm (No. 200) by washing, plus that obtained by dry sieving the same sample, is reported with the results of Test Method C136/C136M. Usually, the additional amount of material finer than 75 μm (No. 200) obtained in the dry sieving process is a small amount. If it is large, the efficiency of the washing operation should be checked. It could also be an indication of degradation of the aggregate.4.2 Plain water is adequate to separate the material finer than 75 μm (No. 200) from the coarser material with most aggregates. In some cases, the finer material is adhering to the larger particles, such as some clay coatings and coatings on aggregates that have been extracted from bituminous mixtures. In these cases, the fine material will be separated more readily with a wetting agent in the water.1.1 This test method covers the determination of the amount of material finer than a 75-μm (No. 200) sieve in aggregate by washing. Clay particles and other aggregate particles that are dispersed by the wash water, as well as water-soluble materials, will be removed from the aggregate during the test.1.2 Two procedures are included, one using only water for the washing operation, and the other including a wetting agent to assist the loosening of the material finer than the 75-μm (No. 200) sieve from the coarser material. Unless otherwise specified, Procedure A (water only) shall be used.1.3 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.NOTE 1: Sieve size is identified by its standard designation in Specification E11. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size.1.4 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.1.5 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.1.6 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 Graffiti on buildings and structures is a significant problem in various regions across the country. A variety of coatings have been developed to be either resistant to the application of paints/marker or to aid in their removal. This standard practice describes a procedure for evaluating the effectiveness of anti-graffiti coatings applied to various concrete, masonry and natural stone substrates. It does not address graffiti removal on metal or any other non-mineral substrate.5.2 This practice only addresses graffiti removal on substrates in a laboratory environment, that have not been exposed to either natural or artificial weathering. Specification D6578 describes a method for graffiti removal after both natural and artificial weathering.1.1 This practice covers a basic method for evaluating the performance of anti-graffiti products on mineral building substrates by a series of increasingly abrasive cleaning methods. The anti-graffiti materials are applied to a series of concrete, masonry and natural stone specimens for evaluation. Graffiti resistance is based on how a defined set of markings are removed by a designated set of cleaning techniques.1.2 This practice also defines a procedure to evaluate graffiti removal after re-marking with subsequent re-cleaning. It does not address the re-treatment of substrates after a material is no longer graffiti resistant.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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.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.

This specification covers the material, design, and performance requirements pertinent to the construction of water-driven rotary spray type, stationary rack commercial pot, pan, and utensil washing machines that are manually fed yet automatically controlled to uniformly wash, rinse, and heat-sanitize food preparation utensils. Representative production models of the washers shall pass performance, operation, leakage, and energy and productivity tests, and should function satisfactorily as specified. Certification, product marking, and packaging are also considered.1.1 This specification covers manually fed, spray-type stationary rack, automatically controlled, water-driven rotary spray commercial pot, pan, and utensil washing machines, herein referred to as “the washer.”1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 The following safety hazards caveat pertains only to the test methods portion, Section 9, of this specification. 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.1.4 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.
