ASTM E3371-22(Test Method)
Standard Test Method for Measuring the Ability of a Synthetic Polymeric Material to Resist Bacterial Adherence

SIGNIFICANCE AND USE
5.1 This method can be used to evaluate the effectiveness of incorporated or bound anti-adherent agents in synthetic polymeric materials and polymeric coatings intended to reduce the attachment of bacteria to the substrate surface.  
5.2 The synthetic polymeric substrate surface may be tested repeatedly over time for assessment of persistent ability of a material to resist bacterial adherence.  
5.3 This method is to quantify the degree of bacteria colonization of a surface to assess a materials ability to resist bacterial adherence because biofilm formation can contribute to material degradation and malfunction.
SCOPE
1.1 This method is designed to evaluate (quantitatively) the number of bacteria attached to the flat, two-dimensional surfaces of synthetic polymeric materials and polymeric coatings on various substrates that may or may not contain bound or incorporated anti-adherent agents. The method focuses on assessing the ability of the surface to reduce bacterial attachment. Other microorganisms such as yeast and fungal conidia may be tested using this method.  
1.2 This test method quantitatively determines the differences in bacterial adherence seen between synthetic polymeric surfaces that allow bacterial adherence and those that do not, comparing the number of organisms recovered from the control surface to the number recovered from the test specimen surface after the contact time. Knowledge of microbiological techniques is required for these procedures.  
1.3 This test method specifies proper methods for measuring the ability of a synthetic polymeric material to resist adherence against specified organism. Due to individual sensitivities, the result of one test organism might not be applicable for other organisms.  
1.4 This test method is designed to measure the potential ability to resist bacterial adherence of a non-porous surface compared directly to a polyester control panel known to support bacterial adherence under specific testing conditions.  
1.5 Antimicrobial treated non-porous surfaces may demonstrate ability to resist bacterial adherence in this method. This method does not purport to differentiate between anti-adherence and antimicrobial activity nor is it designed to reflect specific end-use or environmental conditions. Any product that demonstrates ability to resist bacterial adherence in this method should be measured for antimicrobial activity using a separate test technique such as Test Method E2180 or ISO 22196.  
1.6 The method focuses on assessing the ability of synthetic polymeric materials and polymeric coatings on various substrates to reduce bacterial attachment. The specimen with absorbing or adhesive surfaces may be unable to be disinfected properly before testing, or may trap inoculated organism during recovery process and thus lead to a false result. This method does not apply to specimens with absorbent or adhesive surfaces.  
1.7 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.  
1.8 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.

Standard Guide for Ecological Considerations for the Use of Oil Spill Dispersants in Freshwater and Other Inland Environments, Lakes and Large Water Bodies

SIGNIFICANCE AND USE
3.1 This guide is meant to aid response teams who may use it during spill response planning and spill events.  
3.2 This guide should be adapted to site specific circumstance.
SCOPE
1.1 This guide covers the use of oil spill dispersants to assist in the control of oil spills. The guide is written with the goal of minimizing the environmental impacts of oil spills; this goal is the basis on which the recommendations are made. Aesthetic and socioeconomic factors are not considered, although these and other factors are often important in spill response.  
1.2 Spill responders have available several means to control or clean up spilled oil. Chemical dispersants should be given equal consideration with other spill countermeasures.  
1.3 This is a general guide only. Oil, as used in this guide, includes crude oils and refined petroleum products. Differences between individual dispersants or between different oil products are not considered. The dispersibility of the oil with the chosen dispersant should be evaluated.  
1.4 The guide is organized by habitat type, for example, small ponds and lakes, rivers and streams, and land. It considers the use of dispersants primarily to protect habitats from impact (or to minimize impacts).  
1.5 This guide applies only to freshwater and other inland environments. It does not consider the direct application of dispersants to subsurface waters.  
1.6 In making dispersant use decisions, appropriate government authorities should be consulted as required by law.  
1.7 This guide does not address getting regulatory approval.  
1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.9 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.

Standard Guide for Taking Property and Behavior Measurements on Weathered Fractions of Oil

SIGNIFICANCE AND USE
5.1 A standard procedure is necessary to establish property changes for spilled oils or petroleum products at different oil weathering stages.  
5.2 This procedure employs standardized equipment, and test procedures.  
5.3 This procedure should be performed at the stages of weathering corresponding to the spill conditions of interest.
SCOPE
1.1 This guide summarizes methods to fractionate oil by evaporative weathering and then measure the properties and behavior of the weathered oil. The results of this guide can provide oil behavior data for input into oil spill models and response method selection.  
1.2 This guide covers general procedures for oil weathering and behavior and does not cover all possible procedures which may be applicable to this topic.  
1.3 The results obtained using this guide are intended to provide baseline data for the behavior of oil and petroleum products when spilled and input to oil spill models.  
1.4 The results obtained using this guide can be used directly to predict certain facets of oil spill behavior or as input to oil spill models.  
1.5 The accuracy of the guide depends very much on the representative nature of the oil sample used. Certain oils can have different properties depending on their chemical contents at the moment a sample is taken.  
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.7 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.  
1.8 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.
