Standard Test Methods for Determining Bulk Density of Granular Carriers and Granular Pesticides

Standard Test Methods for Determining Bulk Density of Granular Carriers and Granular Pesticides

SIGNIFICANCE AND USE
These test method is designed principally with clay, corncob, nut shell, paper-based or sand granular carriers, and granular pesticide products, but need not be limited to these materials. There may be more appropriate test methods for other types of granular carriers or pesticide products. The differences in the following test methods are slight, but they offer a choice of a recognized test procedure.
SCOPE
1.1 These test methods are used to determine bulk density of granular carriers and granular pesticides by measuring either free-fall bulk density (Test Method A) or loose-fill bulk density (Test Method B).
1.2 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. For specific hazard statements see Section 4.

Standard Practice to Assess Virucidal Activity of Chemicals Intended for Disinfection of Inanimate, Nonporous Environmental Surfaces

SIGNIFICANCE AND USE
5.1 This practice may be used to determine the effectiveness of liquid, aerosols/foams, and trigger-spray products against designated prototype viruses.  
5.2 The number of lots of the test substance and the number of replicates in each test will depend on the requirements of the target regulatory agency.  
5.3 Certain regulatory agencies may require additional testing using other carrier tests for product registration purposes.
SCOPE
1.1 This practice is used to evaluate the virucidal efficacy of liquid, aerosol, or trigger-spray microbicides intended for use on inanimate, nonporous environmental surfaces. This practice may be employed with most viruses, which can be grown in cultured cells.2 However, other host systems (for example, embryonic eggs) may be used with proper justification and documentation.  
1.2 This practice should be performed only by those trained in microbiological and virological techniques in facilities designed and equipped for work with infectious agents at the appropriate biosafety level.  
1.3 It is the responsibility of the investigator to determine whether Good Laboratory Practice regulations (GLPs) are required and to follow them where appropriate (40 CFR, Part 160 for EPA submissions and 21 CFR, Part 58 for FDA submissions). Refer to the appropriate regulatory agency for performance standards of virucidal efficacy.  
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. The user should consult a reference for laboratory safety recommendations.2

5.2 Regulatory agencies may require additional testing using in vitro (Practice E1053, Test Method E2197) or in vivo (Test Method E1838) carrier tests for product registration purposes.
SCOPE
1.1 This practice is intended to demonstrate the virucidal activity of test substances with viruses in suspension.  
1.2 It is the responsibility of the investigator to determine whether Good Laboratory Practice regulations (GLPs) are required and to follow them where appropriate (40 CFR, Part 160 for EPA submissions and 21 CFR, Part 58 for FDA submissions).

ASTM E1518-05(2019)(Practice)
Standard Practice for Evaluation of Physical Compatibility of Pesticides in Aqueous Tank Mixtures by the Dynamic Shaker Method

SIGNIFICANCE AND USE
4.1 This practice is designed for researchers, applicators, and end users of pesticides where one or more ingredients are being mixed into an aqueous spray system. The practice is useful in determining physical compatibility of aqueous spray mixtures of pesticides and/or fertilizers.  
4.2 The practice is not designed to determine physical compatibility of non-aqueous based spray mixtures.  
4.3 The results or the testing should be used to determine the compatibility of the mixture ingredients in dynamic applications. Interpolation of static results to the expectations of the results of this test is not encouraged.
SCOPE
1.1 This practice describes the method for the evaluation of the physical compatibility and stability of pesticide tank mixtures diluted for aqueous application. This practice may also be adapted to use with liquid fertilizers in replacement of the water diluent.  
1.2 Tank mix compatibility can be affected by many variables. Care should be taken to duplicate test conditions. This practice addresses the standard variables such as time, temperature, water hardness, method of agitation, and degree of agitation.  
1.3 Compatibility is complex and can be affected by other variables such as order of addition, pH of the dilution water, pumping shear, etc. Under the parameters of this practice, the results will define whether the pesticide mixture is or is not compatible in the laboratory. Compatibility or incompatibility should be confirmed under field spray conditions.  
1.4 Proper safety and hygiene precautions must be taken when working with pesticide formulations to prevent skin or eye contact, vapor inhalation, and environmental contamination.  
1.5 Read and follow all handling instructions for the specific formulation and conduct the test in accordance with good laboratory practice.  
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.

ASTM E2316-14(2019)e1(Test Method)
Standard Test Method for Determination of Particles Resulting from the Attrition of Granular Pesticides

SIGNIFICANCE AND USE
5.1 This test method is designed specifically for granular pesticide formulations.  
5.2 This test method helps provide information on health hazards likely to arise from exposures by the inhalation route. It can be of use in selecting dose levels for chronic studies and for establishing safety criteria for human exposure.  
5.3 The amount of fines determined by this method is a measure of potential inhalation and respiration toxicity because the hazards of inhaled solid substances are influenced by physical factors such as particle size.
SCOPE
1.1 This test method is used to determine the amount and particle size distribution curve of particles with diameter 106 micrometers or smaller resulting from the attrition of granular pesticides.  
1.2 The values stated in SI units are to be regarded as 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. For specific hazard statement, see Section 8.  
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.
