ABSTRACT
This specification covers the minimum performance and material requirements for resilient connectors used for connections between reinforced concrete tanks used for septic effluent treatment/detention. All materials shall be suitable for use in sanitary sewage applications. Each connector design shall be tested in accordance with the requirements specified. The following test methods shall be performed: straight alignment; axial deflection; and shear loading.
SCOPE
1.1 This specification covers the minimum performance and material requirements for resilient connectors used for connections between reinforced concrete tanks used for septic effluent treatment/detention, including those referenced in Specifications C913 and C1227.  
1.1.1 These connectors are designed to eliminate leakage between the pipe(s) and tank.  
1.2 A complete metric companion to Specification C1644 has been developed—C1644M; therefore, no metric equivalents are presented in this specification.
Note 1: This specification covers the design, material, and performance of the resilient connection only. Connections covered by this specification are adequate for hydrostatic pressures up to 5 psi (11.5 ft) without leakage when tested in accordance with Section 7. Infiltration or exfiltration quantities for an installed system are dependent upon many factors other than the connectors between tanks and pipes, and allowable quantities must be covered by other specifications and suitable testing of the installed pipe and system.  
1.3 The following precautionary caveat pertains only to the test methods portion, Section 7, of this specification. 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.

SIGNIFICANCE AND USE
5.1 This is not a routine test. The values recorded are applicable only to the tank being tested and at the time of testing. This test is intended only to demonstrate the sealing effectiveness of the installed system. Structural design of the tank is defined or demonstrated within the scope of other applicable specifications and test methods, including Specification C1227.
SCOPE
1.1 This test method covers procedures for testing precast concrete tanks (and installed accessories) used for on-site wastewater treatment, grease interception, grit/oil separation, water storage, or other applications requiring watertight construction and installation. This test method uses partial vacuum to demonstrate the integrity of the installed materials and the construction processes.  
1.2 This test method is intended to be used to demonstrate the condition of the installed system (precast concrete tank and accessories) prior to backfill.  
1.3 Testing of the system before backfill is necessary so as to preclude inadvertent structural overloading of the system components during the test.
Note 1: Vacuum test criteria presented in this test method are similar to those in general use. The test and criteria have been widely and successfully used in testing manholes as specified in Test Method C1244.  
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 and health practices and determine the applicability of regulatory limitations prior to use.

ABSTRACT
This specification covers the minimum performance and material requirements for resilient connectors used for connections between reinforced concrete tanks used for septic effluent treatment/detention. All materials shall be suitable for use in sanitary sewage applications. Each connector design shall be tested in accordance with the requirements specified. The following test methods shall be performed: straight alignment; axial deflection; and shear loading.
SCOPE
1.1 This specification covers the minimum performance and material requirements for resilient connectors used for connections between reinforced concrete tanks used for septic effluent treatment/detention, including those referenced in Specifications C 913 and C 1227.
1.1.1 These connectors are designed to eliminate leakage between the pipe(s) and tank.
1.2 A complete metric companion to Specification C 1644 has been developed-C 1644M; therefore, no metric equivalents are presented in this specification.Note 1
This specification covers the design, material, and performance of the resilient connection only. Connections covered by this specification are adequate for hydrostatic pressures up to 5 psi (11.5 ft) without leakage when tested in accordance with Section 7. Infiltration or exfiltration quantities for an installed system are dependent upon many factors other than the connectors between tanks and pipes, and allowable quantities must be covered by other specifications and suitable testing of the installed pipe and system.
The following precautionary caveat pertains only to the test methods portion, Section 7, of this specification. 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.

SIGNIFICANCE AND USE
This practice is intended to standardize the minimum loads to be used to structurally design a precast product.
The user is cautioned that he must properly correlate the anticipated field conditions and requirements with the design loads. Field conditions may dictate loads greater than minimum.
