Example text

Inspection by the purchaser or failure of the purchaser to provide inspection shall not relieve the constructor or the manufacturer of the responsibility to provide materials and to perform work in accordance with this standard. 4 Tests. Tests the purchaser makes on material samples shall be made without delay. If any sample fails to meet the requirements, the manufacturer shall be notified immediately. Material affected by the test results shall be set aside pending final disposition. 5 Notice of Nonconformance.

Material affected by the test results shall be set aside pending final disposition. 5 Notice of Nonconformance. Material and pipe that are discovered to be defective or that do not conform to the requirements of this standard may be repaired in accordance with the provisions of this standard. An effort shall be made by the purchaser to inspect the pipe in the manufacturer’s plant pursuant to Sec. 1. Nonconforming material and pipe shall be removed from the work site within a reasonable period of time.

The joint shall be filled with cement mortar by pouring from one side only until the cement mortar reaches at least the pipe spring line on the opposite side, and shall be rodded with a wire or other flexible rod, or vibrated so that the cement mortar completely fills the joint recess by moving down one side of the pipe, around the bottom of the pipe, and up the opposite side. Pouring and rodding the cement mortar shall be continued to allow completion of the filling of the entire joint recess in one operation.
