USCG/CEPS/IMO Pollution Prevention Certification: NSF is a USCG-recognized facility for marine sanitation devices and oil pollution prevention equipment. Testing is available worldwide through NSF, at NSF facilities, manufacturer's facilities or at land-based or shipboard sites.
Flushability Testing: Evaluations are carried out in either a laboratory test rig or in full-scale systems. The testing provides manufacturers with information to assist them in product development and/or evaluating the ability of their products to clear building plumbing systems.
Full Scale Sewer System Evaluations: Determine the impact and fate of products in municipal sewer systems and headworks of wastewater treatment plants.
On-site Septic Tank and Aerobic Treatment System Evaluations: Completed in full-scale systems, these evaluations provide information about the impact and fate of products on the system. The information is useful in determining the potential for problems with on-site disposal of the products.
Aerobic and Anaerobic Biodegradation: Aerobic biodegradation of materials is determined using a respirometer, which measures the oxygen uptake of organisms exposed to the test materials. Anaerobic biodegradation is determined from evaluation of the quantities and characterization of the gas produced during exposure of the materials to anaerobic bacteria.
Compost Evaluations: Specialized systems provide for evaluation of products under compost conditions. One system provides for determining the impact on the physical properties of the material when exposed to compost conditions. The second system provides for determination of the biodegradation potential of materials under compost conditions.
Special Protocol Development: NSF's unique position with respect to public health and government agencies, along with contacts in academia and the private sector, provides NSF with resources to supplement the expertise of the staff in developing new test methods for specific products.
