8.2 Length -- Pipe shall be furnished in standard 3.82-m (l2'/.-ft) lengths with a tolerance of -25 mm (-1 in.), when meas ured in accordance with 10.6.1. There is no limit for plus variation. Other lengths may be provided, if agreed upon by the purchaser and the seller.
8.3 Straightness -- Pipe intended to be straight shall have a maximum deviation from straightness of 4.85 mm/m ('/.6 in./ft) of length, when measured in accordance with 10.6.1.

h prior to lest in accordance with Procedure A of Methods D 618 for those tests where condi tioning is required. In cases of disagreement, 'he tolerances shall be I C I 1.8 FI and 2 percent relative humidity.
10.2 Test Conditions--Conduct tests in the Standard Laboratory Atmosphere of 23 2 C (73.4 3.6 F) and 50 5 percent relative humidity, unless otherwise specified in the test methods or in this specification. In cases of disagreement, the tolerances shall be I C (it 1.8 F) and 2 percent relative humidity.
10.3 Stiffness and Deflection: 10.3.1 Test three 150-mm (6-in.) long speci mens cut from each sample using the appara tus described in Method D 2412. Compress the specime.n to record the load Jl 5 percent \ertical deflection and to record the vertical deflec tion at rupture of either wall. 10.3.2 Calculate the percentage vertical deflection as follows:
Vertical deflection, perceni = (Ai /Nominal ID) X 100
where Ar = vertical deflection of the inside diameter.
Both ID and Ac must be in the same units. 10.3.3 Calculate the pipe stiffness at 5 per cent deflection as follows:
Pipe stiffness (PSl = f/Ai
where F = load recorded at 5 percent deflec tion.
Note 5-If F is expressed in newtons metre, and Ai is in metres, then PS is given in NmJ: if F is exprgs'.ed in pounds-force/inch. and Ai is in inches, then PS is given in psi.
10.4 Acid Conditioning--Completely im merse three 150-mm (6-in.) long specimens cut from each sample in a suitable vat con taining a 5 percent solution by weight of sul furic acid. Allow the specimen to remain submerged for 24 h. After removal from the acid, wash the specimen with running water, wipe with a clean, dry cloth, condition for 2 h and then lest in accordance with 10.3 within 30 min.
10.5 Joint and Fitting Tightness--Assemble Type SC joints by first applying a coat of primer to the inside of the socket and to the outside of the spigot end of pipe Without de lay. apply a coating of cement to the same surfaces in sufficient quantity that when the spigot is fully inserted into the socket, a bead
of excess cement will form around' the com plete circumference of the outside juncture of the spigot and socket. Remove the excess ce ment and allow the assembly to cure for 24 h. Assemble Type OR joints by any convenient .means so that the joint components are lo cated as shown in Fig. I. It is recommended that a lubricant, such as soap and water, be used. Seal all open ends by any convenient method and apply an internal hydrostatic head of 70 kPa (10 psi) to the assembly for I h. Observe evidence of any leakage. Leakage through the inert filler shall not be considered reason for rejection.
10.6 Dimensions: 10.6.1 Dimensions -- Measure the average outside diameter by use of a circumferential wrap tape, out-of-roundness for maximum diameter, inside diameter, length, straight ness. coupling thickness, and socket inside diameter in accordance with Method D 2122.
10.6.2 Concentric Tube Thickness--Meas ure the minimum average inner and outer concentric thermoplastic tube thickness in ac cordance with Section 4 of Method D 2122. Remove the other component prior to meas urement in a manner so as to obtain clean sur faces.
10.6.3 End Squareness--Determine the pipe end squareness by placing a right angle square against the pipe outside at the pipe end and determine to the nearest 0.25 mm (0.01 in.) the maximum gap to the inside edge of the tool arm.
11. Inspection
II I Inspection of the material shall be made as agreed upon by the purchaser and the seller as part of the purchase contract.
12. Retest and Rejection
12.1 If any failure occurs, the materials may be retested to establish conformity in accordance with agreement between the pur chaser and the seller.

APPENDIX
XI. UNDERGROUND INSTALLATION
XI.I Recommended Practice D 2321 is recom
mended as a guide for installing this pipe. The maxi mum size of particles used in the materials around the pipe may be 40 mm (1' i in.) without impairing the effectiveness of the installation. Soil containing
('rozen earth, debris, or rocks larger than I 1: in. diameter and soils identified in the Unified Soil Classification System as MH. CH. OL. OH. and PT should not be used as bedding, haunching. or initial backfill. Soil types M L and CL require care in place
ment to ensure full pipe peripheral contact.
X1.2 The procedures for placing and compacting
the bedding, haunching and initial backfill materials shall be as described in the specification, except when using the allowable soils in Classes II. 111. and IV. The haunching and initial backfilling for these soils shall be placed completely under the pipe haunches and up each side in uniform layers not exceeding 152 mm (6 in.) in depth, with each layer carefully and uniformly tamped. The minimum
cover for wheel or hydrohammer loads is 610 mm (24 in.).
The Ahterican Society for Testing and Materials takes no position respecting the validity ofany patent rights asserted in connection with any item mentioned in this standard. Users ofthis standard are expressly advised that determination
of the validity ofany such patent rights, and the risk of infringement of such rights, is entirely their own responsibility.
