  2. AWWA Pipe Standards Update • AWWA C900 & C905 Combined • New ballot out April 30, 2013 Proposes: • Combines the two PVC standards into one • Adds classes of pipe not included in C905-10 • Provides common design approach across all PVC pipe with a DF =0.5 applied to an HDB = 4000 psi for operating pressure rating. • Occasional Surge Allowance • Recurring Surge Design Procedure for all sizes.

  3. AWWA Pipe Standards Update • AWWA C900 & C905 Combined (Cont’d) • New qualification requirements for different joining systems including: • Gasketed Bell and Spigot Joints (D3139, Quick Burst and Every Joint Proof Test) • Restrained Joints (same plus ASTM D1716) • Fused Joints (same plus ASTM D1716 on all sizes)

  4. CSA Pipe Standards Update • CSA B173.3 (Added Products) • 24-inch DR 14, 21 • 30-inch DR 18, 21 • 36-inch DR 18, 21 • 42-inch DR 21, • 48-inch DR 25, • 54-inch DR 51 and 41 • 60-inch DR 51 and 41

  7. ASTM Pipe Standards Update • ASTM D2152 Fusion by Acetone Immersion • Revised to standardize test sample geometry • This will minimize differences seen in lab to lav testing when sample geometer may not have fully exposed the entire wall cross-section.
