• 2002: HSB policy to substantiate PE compounds to 50 years at 73F (23C).

• 2007: HSB introduces two new policies:

− Material specific policy for CPVC compounds for solid wall pipe.

− Policy whereby PE compounds can apply a 0.63 DF afterdemonstrating a higher ductile capacity, improved resistance to slow crack growth and reduced variability of the hydrostatic data.

• 2012: HSB adopts ASTM D2992 into policy for fiber-reinforced thermosetting andthermoplastic-resin composite pipe constructions.

• 2014: HSB defines two new committees to better serve the industry: Research & Development (R&D) and Design Factor (DF) Committees

• 2015: HSB publishes The Nature of the 0.63 Design Factor (DF) for QualifiedPolyethylene Pipe Compounds (HSB-R01/2015).

• 2016: New PPI HSB web section launched to allow for easier accessibility to theprogram and the first ever PPI HSB TR Policy Course conducted to help preserve the knowledge datum in the industry.

• 2017: PPI HSB completes and implements the PPI TR-4 5-Year Renewal Policy.

- Hydrostatic sustained pressure test and cell classification data required to renew PPI TR-4 Independent Standard Grade level listings expiring EOY 2018 and all future years.

• 2018:

− HSB publishes Policy for Colorant Changes in PEX Pipe and Compounds (HSB-N1).

− Introduce PPI TR-2 policies for Dependent Listings of the PPI PVC Range Composition

− HSB redefines composite pipe to reflect the current industry and publishes new definitions; restructure of composite policies begins (new Part K to reflect the structures used today).

**In October, PPI membership resoundingly passed a budget supporting a role restructure: A new engineer will assume responsibilities for the PPI Technical Committee (TC), Power & Communication Division (PCD) and Education Committee. This allows S. Patterson to move 100% to the PPI HSB and L. MacNevin to move 100% to the Building & Construction Division (BCD). The official search begins this March with the intent to hire mid-year.

▪ The PPI HSB is recognized for technical excellence and practice of good science.

▪ The PPI HSB listings demonstrates the high level of commitment to quality bymanufacturers and the global thermoplastic pressure pipe industry.

▪ The PPI HSB policies and voluntary listing program is cited in product standards developed by organizations such as ASTM International, American Water Works Association (AWWA), CSA Group, and certification programs such as NSF International. Code bodies such Department of Transportation Pipeline and Hazardous Materials Safety Administration (DOT PHMSA), Nuclear Regulatory Commission (NRC) and others, also reference due to the rigorous requirements, good science and involvement in the industry since the early 1950s.

▪ End users recognize the credibility of the PPI HSB listings as a rigorous ‘due diligence' process is used to qualify for and to maintain the listing.

▪ The PPI HSB contributes to the confidence level of plastic pipe systems used in the different pressure pipe applications.
