For Laboratory testing and sample reporting procedures, refer to EPG 1027.4 Laboratory Testing Guidelines for Sec 1027.
Contents
1027.1 Apparatus
(a) Magnetic or electronic gauge, reading range 0-40 mils (0-1000 μm).
(b) Micrometer capable of measuring to 0.0001 in. (0.00254 mm) and accurate to within at least 0.001 in. (0.0254 mm).
(c) Rule with suitable gradations to accurately measure the material to be inspected.
(d) The Corrugated Metal Pipe (CMP) Inspection Guide.
1027.2 Procedure
1027.2.1 Polymer-Coated Corrugated Metal Culvert Pipe and Pipe-Arches
Polymer-coated corrugated metal culvert pipe and pipe arch is to be accepted in accordance with Sec 1027.2.
1027.2.2 Material
The pipe shall be in accordance Sec 1020 and Sec 1027. The polymer material shall be in accordance with AASHTO M 245.
1027.2.3 Identification Markings
Pipe is to be marked in as described in 1020.2.3 Identification Markings for Steel Sheet.
1027.2.4 Random Sampling
Random samples are to be taken in as described in EPG 1020.2.4 Random Sampling of Steel Sheet. Random samples of polymer coating are to be taken as described in AASHTO M 245.
Samples for determination of coating thickness may be taken from fabricated pipe.
