Standard Test Method for Determining Spray Patterns of Manually Operated Pump Dispensers

Standard Test Method for Determining Spray Patterns of Manually Operated Pump Dispensers

SIGNIFICANCE AND USE
This practice can be used to compare spray patterns of different pump dispensers and of different products.
Spray patterns from pump dispensers will vary greatly with the design of the actuator and the nature of the liquid. Liquids with differing physical properties will not necessarily yield the same spray pattern when sprayed from the same actuator. Likewise, actuators of different designs will yield spray patterns distinct from each other when the same liquid is used.
SCOPE
1.1 This test method covers the determination of spray patterns from pump dispensers.
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.

Standard Test Method for Measuring Aspiration Potential of Aerosol Products

SIGNIFICANCE AND USE
4.1 This test method provides a means of measuring whether or not an aerosol product may present an aspiration risk if a dispensed aerosol gets into one’s mouth.  
4.2 The degree of risk for aspiration of an aerosol depends both on spray pattern as well as aerosol deposition rate.2  
4.3 This test method will be used to determine the need for child-resistant packaging of aerosol products.
SCOPE
1.1 This test method covers a small-scale laboratory procedure to determine the aspiration potential of aerosol products by determining spray pattern and aerosol deposition rates.  
1.2 This test method has been developed to address a need to identify which aerosol products may present an aspiration risk such that special labeling and/or child-resistant packaging would be appropriate. Studies based on this method may allow the development of a practice to identify such aerosol products.  
1.3 Although this method may be useful for testing non-pressurized aerosol products, its development has been limited to testing pressurized aerosols.  
1.4 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.  
1.5 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.

Standard Test Method for Determining Liquid Drop Size Characteristics in a Spray Using Optical Nonimaging Light-Scattering Instruments

SIGNIFICANCE AND USE
5.1 The purpose of this test method is to provide data on liquid drop-size characteristics for sprays, as indicated by optical nonimaging light-scattering instruments. The results obtained generally will be statistical in nature. The number of variables concerned in the production of liquid spray, together with the variety of optical, electronic, and sampling systems used in different instruments, may contribute to variations in the test results. Care must be exercised, therefore, when attempting to compare data from samples obtained by different means.
SCOPE
1.1 The purpose of this test method is to obtain data which characterize the sizes of liquid particles or drops such as are produced by a spray nozzle or similar device under specified conditions using a specified liquid. The drops will generally be in the size range from 5-μm to the order of 1 000-μm diameter; they will occur in sprays which may be as small as a few cubic centimetres or as large as several cubic metres. Typically the number density of the particles can vary significantly from one point to another.  
1.2 This test method is intended primarily for use in standardizing measurements of the performance of sprayproducing devices. It is limited to those techniques and instruments that operate by passing a beam of light through the spray and analyzing the light scattered by the droplets to derive size information. Such techniques do not produce images of individual drops, and therefore, are known as “optical (nonimaging) instruments.”  
1.3 The measurements made, when referred to the entire spray being sampled, may be flux sensitive or spatial, as defined in Practice E799, depending on the techniques used with a particular instrument.  
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.

ASTM E2872-14(2019)(Guide)
Standard Guide for Determining Cross-Section Averaged Characteristics of a Spray Using Laser-Diffraction Instruments in a Wind Tunnel Apparatus

SIGNIFICANCE AND USE
5.1 This guide provides a means of using an LD instrument to obtain a droplet size distribution from a spray in gas co-flow that approximates a flux-sensitive sample.4  
5.2 In many sprays, the experimenter shall account for spatial segregation of droplets by size. This guide provides a means of spatial averaging the droplet distribution.  
5.3 The results obtained will be statistical in nature and refer to the time average of droplet size distribution of the entire spray.  
5.4 This guide is used to calibrate a spray generation device to produce a desired droplet size distribution under prespecified environmental and co-flow conditions or characterize an unknown spray while minimizing the uncertainty in the measurement.
SCOPE
1.1 The purpose of this guide is to define a test procedure for applying the laser diffraction (LD) method to estimate an average droplet size distribution that characterizes the flux of liquid droplets produced by a specified spray generation device under specified gas co-flow conditions using a specified liquid. The intended scope is limited to artificially generated sprays with high speed co-flow. The droplets are assumed to be in the size range of 1 to 2000 µm in diameter and occur in sprays that are contained within a volume as small as a few cubic centimetres or as large as a cubic metre. The droplet sizes are assumed to be distributed non-uniformly within the spray volume.  
1.2 This guide is intended primarily to guide measurement of performance of nozzles and atomizers using LD instruments.  
1.3 Non-uniform sprays require measurements across the entire spray cross section or through several chords providing a representative sample of the overall spray cross section. The aim of multiple-chord measurements is to obtain a single droplet size distribution that characterizes the whole spray rather than values from a single chordal measurement.  
1.4 Use of this guide requires that the instrument does not interfere with spray production and does not significantly impinge upon or disturb the co-flow of gas and the spray. This technique is, therefore, considered non-intrusive.  
1.5 The computation of droplet size distributions from the light-scattering distributions is done using Mie scattering theory or Fraunhofer diffraction approximation. The use of Mie theory accounts for light refracted through the droplet and there is a specific requirement for knowledge of both real (refractive) and imaginary (absorptive) components of the complex index of refraction. Mie theory also relies on an assumption of droplet homogeneity. The Fraunhofer diffraction approximation does not account for light refracted through the droplet and does not require knowledge of the index of refraction.  
1.6 The instruments shall include data-processing capabilities to convert the LD scattering intensities into droplet size distribution parameters in accordance with Practice E799 and Test Method E1260.  
1.7 The spray is visible and accessible to the collimated beam produced by the transmitter optics of the LD instrument. The shape and size of the spray shall be contained within the working distance of the LD system optics as specified by the instrument manufacturer.  
1.8 The size range of the LD optic should be appropriate to the spray generation device under study. For example, the upper bound of the smallest droplet size class reported by the instrument shall be not more than 1/4 the size of DV0.1.  
1.9 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.10 This standard may involve hazardous materials, operations, and equipment. 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 limita...
