ASTM D4333/D4333M-18

Standard Practice for Compatibility of Mechanical Pump Dispenser Components

SIGNIFICANCE AND USE
2.1 This practice identifies the compatibility of the mechanical pump dispenser components with consumer-type products.
SCOPE
1.1 This practice covers testing of the components of mechanical pump dispensers (spray or flow types) for compatibility with products.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with 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.  
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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

two systems may result in non-conformance with the standard.
1.3 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 consult and establish
appropriate safety safety, health, and healthenvironmental practices and determine the applicability of regulatory limitations prior
to use.

4. Test Specimen
4.1 At least three individual components should be used for each part tested with each product involved at each test condition.
4.2 At least three individual components are used as controls at each test condition.
4.3 Individual unassembled components shall be clean and previously unused.
5. Conditioning
5.1 Condition test specimens at 23 6 3°C [73.46 5.4°F] for at least 4 h prior to testing. If test specimen conditioning is not
possible, the environmental conditioning of the test specimens tested should be included in the report as discussed in 7.1.
5.2 Test conditions shall be an elevated temperature of 45 6 3°C [113 6 5.4°F] and an ambient room temperature of 23 6 3°C
[73.4 6 5.4°F]. If a different temperature is used, this should be noted in the test report discussed in 7.1.

6. Procedure
6.1 Dimensional and Weight Changes:
6.1.1 Prior to immersion into the product, weigh the part and record as W1 (see 7). Measure the thickness or overall length of
the part to the nearest 0.025 mm [0.001 in.] of each component depending on which of these dimensions are most important (for
example, thickness for a gasket or liner, and overall length for a molded component). Optionally, measure a diameter of the part
to its nearest 0.025 mm [0.001 in.]. Report the data as initial dimension D1 (see 7). This data is reported as a mean value of the
dimension for the components measured for that particular part.
6.1.2 Maintain at least three test specimens as visual comparison controls. Do not immerse these control test specimens in any
solution
