ASTM F667-16(R2021) pdf free download.Standard Specification for 3 through 24 in. Corrugated Polyethylene Pipe and Fittings
1. Scope
1.1 This specification covers requirements and test methods for materials, workmanship, dimensions, perforations, pipe stiffness, elongation, joint separation resistance, quality of extruded polyethylene, brittleness, bond, and marking of cor- rugated polyethylene (PE) pipe and fittings. It covers nominal sizes 3 in. [76 mm], 4 in. [102 mm], 5 in. [127 mm] 6 in. [152 mm], 8 in. [203 mm], 10 in. [254 mm], 12 in. [305 mm], 15 in. [381 mm], 18 in. [457 mm], and 24 in. [610 mm]. 1.2 This specification covers tubularly extruded, spirally laminated, and rotationally molded corrugated polyethylene pipe. 1.3 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. 1.4 The following precautionary caveat pertains only to the test method portion, Section 9, of this specification: This standard does not purport to address all ofthe safety concerns, ifany, associated with its use. It is the responsibility ofthe 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 accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
5. Materials
5.1 Basic Materials—Compounds used in the manufacture of corrugated PE drainage pipe and fittings shall have a minimum cell classification of323410C or 333410C as defined and described in Specification D3350. Compounds that have a higher cell classification in one or more properties are acceptable, provided the product requirements are met. N OTE 1—Class B pigments may be substituted for Class C provided that ultraviolet protection is acceptable to the publisher as satisfactory for the intended use. 5.2 Rework Material—Clean rework material, generated from the manufacturer’s own production of the product, may be used by the manufacturer provided that the tubing and fittings produced meet all requirements of this specification.
6. General Requirements
6.1 Workmanship—The pipe and fittings shall be homog- enous throughout and essentially uniform in color, opacity, density, and other properties. The inside and outside surfaces shall be semimatte or glossy in appearance (depending on the type of plastic) and free of chalking, sticky, or tacky material. The pipe and fitting walls shall be free ofcracks, holes, blisters, voids, foreign inclusions, or other defects that are visible to the naked eye and that may affect the wall integrity. Holes deliberately placed in perforated pipe are acceptable. The surface shall be free of excessive bloom. Bloom or chalking may develop in pipe exposed to the direct rays of the sun (ultraviolet radiant energy) for extended periods; consequently, these requirements do not apply to pipe and fittings after extended exposure to direct rays of the sun. N OTE 2—Wall thickness may vary within each corrugation. Variation is acceptable provided the tubing meets all physical requirements.
7. Detail Requirements
7.1 General: 7.1.1 The following requirements shall be met by perforated or nonperforated pipe, as applicable. 7.1.2 Individual results shall be used to determine compli- ance with the requirements, unless otherwise stated. 7.2 Dimensions and Tolerances: 7.2.1 Pipe: Nominal Diameter—The nominal diameter of the pipe shall be the average inside diameter rounded to the nearest whole number. Inside Diameter—The tolerance on the nominal inside diameter shall be +3 %; −1.5 %, when measured in accordance with 9.3. Length—The pipe may be sold in any length agree- able to the user. Length shall not be less than 99 % of stated quantity, when measured in accordance with 9.4. 7.2.2 Fittings: The maximum allowable gap between pipe and fitting shall not exceed 1 ⁄ 8 in. [3 mm] unless otherwise specified. 7.3 Perforations: 7.3.1 Drainage Pipe—When perforations are necessary, they shall be cleanly cut and uniformly spaced along the length and circumference of the pipe in a size, shape, and pattern suited to the needs of the user. 7.3.2 The inlet area of the perforations shall be a minimum of 1 in. 2 /ft [21 cm 2 /m] of pipe, unless otherwise specified by the user. 7.4 Pipe Stiffness—The pipe shall have a minimum pipe stiffness of30 psi [0.21 MPa] at 5 % deflection and 25 psi [0.18 MPa] at 10 % deflection, when tested in accordance with 9.5. 7.5 Elongation—Continuously extruded pipe that elongates more than 5 %, but less than 10 %, when tested in accordance with 9.6, shall meet the requirements of 7.4 when tested in accordance with 9.7. Pipe that elongates more than 10 % shall be rejected. 7.6 Brittleness—Pipe and fitting specimens shall be tested in accordance with 9.9.
