ASTM F877-20 pdf free download.Standard Specification for Crosslinked Polyethylene (PEX) Hot- and Cold-Water Distribution Systems.
ASTM F877-20 covers requirements, test methods, and marking requirements for system components when tested with nominal SDR9 crosslinked polyethylene (PEX) tubing as a system. Systems are intended for 100 psi (0.69 MPa) water service up to and including a maximum working temperature of 180 °F (82 °C). Requirements and test methods are included for materials, workmanship, dimensions and tolerances, burst pressure, hydrostatic sustained pressure, excessive temperature and pressure, corrosion resistance, and thermocycling tests. The components covered by this specification are intended for use in, but not limited to, residential and commercial hot and cold potable water distribution systems or other applications such as reclaimed water, fire protection, municipal water service lines, radiant heating and cooling systems, hydronic distribution systems, snow and ice melting systems, geothermal ground loops, district heating, turf conditioning, compressed air distribution, and building services pipe.
8. Retest and Rejection
8.1 If the results of any test do not meet the requirements of this specification, the tests(s) shall be conducted again only by agreement between the purchaser and seller. Under such agreement. minimum requirements shall not be lowered changed, or modified, nor shall specification limits be changed If upon retest, failure occurs, the quantity of product repre sented by the test(s) does not meet the requirements of this specification.
9. Certification
9.1 PEX system components intended for use in the trans port of potable water shall be evaluated and certified as safe for this purpose by a testing agency acceptable to the local health authority. The evaluation shall be in accordance with the requirements for chemical extraction, taste, and odor, that are no less restrictive than those included in NSF/ANST Standard No.14 and NSE/ANS Standard No.61. The seal or mark of the laboratory making the evaluation shall be included on the system components.
11. Quality Assurance
11. 1 When the product is marked with this designation,F877 or the with the specific standard specification for the system component, the manufacturer affirms that the product was manufactured, inspected sampled and tested in accordance with this specification and has been found to meet the requirements of this specification.
