Cast Iron Pipe and Fittings manufactured to ASTM A74, ASTM A888 and CISPI 301 are not Special (Acid) Waste Pipe and Fittings.

Epoxy Coated Cast Iron Pipe is Not Suited for Acid Waste Applications | False Claim: Epoxy painted cast iron pipe and fittings can be used in Special (Acid) Waste applications and are a cost effective alternative to traditional Special (Acid) Waste products. False Claim Documentation: Epoxy painted cast iron is "A cost effective alternative to plastic, acid waste, glass pipe, durion, and stainless steel. We offer a solution to existing pipe materials, sizes, and specifications."

CHAPTER 8 - Indirect Wastes, 811.2 reads "811.2 Each waste pipe receiving or intended to receive the discharge of any fixture into which acid or corrosive chemical is placed, and each vent pipe connected thereto, shall be constructed of PP, PVDF, chemical-resistant glass, high-silicon iron pipe, or lead pipe with a wall thickness of not less than one-eighth (1/8) inch (3.2 mm); an approved type of ceramic glazed or unglazed vitrified clay; or other approved corrosion-resistant materials". Thus, gray cast iron, regardless of coating, is not allowed by the plumbing code Chapter 8. In fact, the standards for gray cast iron pipe and fittings are ASTM A74, A 888 and CISPI 301. These standards are not found in the special (acid) waste section of the plumbing code. They are only found in the DWV section of the plumbing code.

Cast iron pipe and fittings are not acceptable by code to be used for special (acid) waste. Cast Iron Pipe and fittings, regardless of coating, are only appropriate for drain, waste and vent (DWV) applications by code.

Standards

Epoxy painted cast iron pipe and fittings can be used in Special (Acid) Waste applications because they "allegedly" conform to a portion of the European DWV epoxy cast iron standard. False Claim Documentation: "Specification & Standards: ASTM - A888, CISPI 301, EN 877 Coating Specification & Testing"
Source: NewAge Epoxy Catalog as of 8/1/2014
EN 877:1999 Standard, Page 4, 1 Scope reads: "The European Standard applies to cast iron pipeline components used for the construction of discharge systems for buildings and of drains, normally as gravity systems." Thus, European epoxy cast iron is not appropriate for special (Acid) waste applications.
Source: EN-877:1999, page 4
EN 877 is only for sanitary and storm drain, waste, and vent piping. The scope does not allow for use in special (acid) waste applications. Furthermore, EN 877 is not recognized by any US code. Conclusion: Cast iron pipe and fittings, regardless of coating, are not acceptable per applicable standards to be used for special (acid) waste. Cast Iron Pipe and fittings are only appropriate for DWV applications per applicable standards.

New Age Epoxy pipe and fittings do not have a listing for special (acid) waste.

NewAge Epoxy Submittal reads:


"- Certified to conform to ASTM A888-11 Standard Specification and CISPI 301 for No-Hub Cast Iron and Fittings through IAPMO R&T Laboratory File 4818.
- NewAge Soil Pipe Products No-Hub Cast Iron Soil Pipe and Fittings meet the requirements of ICC International Plumbing Code 200 for material outlined in Chapter 7 for sanitary drainage systems (Sections 702, 705 & 708)."


Thus, New Age's listings are only to DWV standards, not Special (Acid) Waste standards.
Source: NewAge Epoxy Catalog, Page 3
New Age's Epoxy listings only claim to "allegedly" meet the standards for sanitary and storm drain, waste, and vent (DWV) and do not claim to meet the standards for special (acid) waste applications. Conclusion: Cast iron pipe and fittings, regardless of coating, are not acceptable per listings to be used for special (acid) waste. Cast Iron Pipe and fittings are only appropriate for DWV applications per listings.

Are you willing to assume the risk for specifying, installing or selling a "falsely alleged" Special (Acid) Waste product that:

  1. is not Code approved;
  2. does not meet Acid Waste Product Standards; and
  3. is not listed for special (acid) waste applications?
