Understanding Design Standards & Our Tanks

By May 4, 2021May 7th, 2021Tanks

At Peabody, we do much of our design and production processes in-house, including our own tooling and rotational plastic molding, which we put through our internal rigorous testing protocols, so we ensure quality at every step of the process. But that is just the beginning. Our tanks are certified and rated by some of the largest governing bodies and standards in North America.

Product certifications might seem like an alphabet soup of acronyms and labels, but they are a very important indicator that a product has been tested to government or other third-party standards and regulations. What does that mean for our customers who buy our certified tanks? It’s an assurance of safety, reliability and quality from both a design and manufacturing perspective.

NSF/ANSI/CAN 61

ProChem® Potable Water Tanks

Our ProChem® Tanks and Gemini Dual Containment® Tanks made from Linear Polyethylene (LPE) are NSF/ANSI/CAN 61 Certified.

NSF is one of the most respected independent certification organizations in public health and safety across the globe. Having the NSF mark lets consumers, distributors, suppliers and regulators know that our tanks have been rigorously tested to comply with all standard requirements.

NSF 61 is the only American National Standard addressing the human health effects of drinking water system components. It is a performance-based standard that evaluates the amount of contaminants that leach from our tanks into drinking water, rather than setting prescriptive limits on content.

The NSF certification process can be long and costly, but it’s part of our commitment to the industry and to our customers. Though the process is product-specific and can get quite technical, generally, here is a summary of the seven steps:

  1. Application and information submission
  2. Product evaluation
  3. Product testing in lab
  4. Manufacturing facility inspection, production confirmation and product sampling
  5. Test results review and acceptance
  6. Contract signed and products listed
  7. Annual plant inspection and retesting

ASTM D 1998 Standard

Gemini Dual Containment Plus

Gemini PLUS

Our Gemini®, Gemini® PLUS 1300 and Prochem® Tanks in LPE, HDPE, XLPE, PPL or PVDF construction are available ASTM D-1998 rated if desired.

American Society for Testing and Materials, or ASTM has designed and set over 12,800 standards that help improve lives and enhance performance and help consumers have confidence in the products they buy and use. That includes ASTM D 1998, a set of standards for cross-linkable polyethylene (XLPE) and non-cross linkable polyethylene (HDPE) polyethylene vertical tanks over 500 gallons.

ASTM D 1998 defines minimum wall thicknesses for these tanks based on several criteria like height, outside diameter, and specific gravity rating. To comply with the standards, the tanks must go through a series of tests that check:

  • Wall thickness test
  • Impact Test
  • Structural integrity test

Additionally, there is a test for cross-linked polyethylene (XLPE) tanks to measure the chemical makeup of the tank materials.

EPA 49 CFR

Gemini Dual Containment

Gemini Dual Containment® Tanks

Peabody’s Gemini Dual Containment® Tanks meet or exceed secondary containment requirements under the EPA’s 49 CFR Regulations.

The Environmental Protection Agency, OSHA, and the Department of Transportation provide regulatory and enforcement functions for laws promulgated by the U.S. Congress that are designed to protect the environment from contamination and reduce risks to human health and worker safety. They have specific requirements for hazardous chemical safe storage compliance. These regulations are codified in the Code of Federal Regulations: 40 CFR Protection of the Environment, 29 CFR Labor, and 49 CFR Transportation, respectively.

FDA Approved

Our ProChem® Potable Water Tanks are also FDA approved. Though the FDA doesn’t approve equipment used in food processing, they have created a set of requirements that equipment used in food and beverage storage must meet.
