Description / Abstract:
The purpose of this fuel filter test method is to provide
standardized methods for evaluating the performance characteristics
of fuel filters by bench test methods. This, combined with data
obtained from application tests, may be used to establish standards
of performance for filters when tested by these standard methods.
Many variations in requirements of filtration to protect fuel
supply equipment on engines and variations in operating conditions
make it difficult to specify meaningful "in-service" performance
standards by which a filter may be judged. By the use of these
standard test methods, test conditions are always the same, and
comparisons of the laboratory performance of filters may be made
with a high degree of confidence. Once the requirements of a
particular application are known, performance standards for
suitable filters may be established by these test methods, and
adequacy of performance of filters for the job may be
determined.
In order to achieve the highest degree of reliability of test
results, the procedures and equipment must conform to those
specified in this code. No minimum performance requirements for
filters have been specified, since these are the responsibility of
the user and manufacturer. Only the methods of determining,
interpreting, and reporting performance characteristics are the
proper province of this SAE Standard.
Separate chapters cover the test methods necessary to evaluate
the several functional capabilities and mechanical properties of
the filter. Each chapter is complete with recommended materials,
apparatus, and procedures for testing and evaluation. The chapters
are:
a. Chapter 1 - Resistance to Flow (Section 3)
b. Chapter 2 - Filter Capacity and Contaminant Removal
Characteristics (Section 4)
c. Chapter 3 - Media Migration Test (Section 5)
d. Chapter 4 - Collapse Test (Section 6)
e. Chapter 5 - Ability to Meet Environmental Conditions (Section
7)
f. Chapter 6 - Installation and Removal (Section 8)
g. Chapter 7 - Mechanical Tests (Section 9)
h. Chapter 8—Material Compatibility (Section 10)
To simplify the chapters covering test methods, information of
importance but not directly involved in test methods is covered in
appendices as follows:
