New Specification for Manufacturing Design of a Non-Adjustable Pipe Deflection Go No-Go Test Mandrel
1. Scope
The new Standard will cover all flexible sewer pipe materials (i.e. ductile iron, fiberglass, polymer concrete, profile wall thermoplastics, etc.) The new Standard will also include (but not limited to): Standardization of Mandrel manufacturing and design; Mandrel Testing Standard Operating Procedures; Deflection Baseline Diameters and Calculations; Backfill, Compaction, and settlement Criteria; Operator Safety and Mandrel Testing Certification.
Keywords
deflection, mandrel, testing, backfill, sewer
Rationale
Currently, there are no ASTM standards for post installation testing of flexible sewer pipe during the installation of or as a determining factor for the final acceptance of the project.
