Custom Testing and R&D Lab Services
These fractures are characterized by the stable growth of a crack with little deformation in the plastic material. SCG testing involves accelerating the growth mechanism and can be done through elevated temperature, concentrated stress, constrained geometry, surfactants or some combination of these factors. These test methods are applicable to polyethylene (PE), polypropylene (PP) and polybutylene (PB) piping.
Rapid crack propagation (RCP) is a fast fracture type of failure. Cracks are thought to initiate at internal defects on an impact of impulse event and can travel long distances quickly. RCP occurs in pressurized systems with enough stored energy to drive cracks faster than energy is released. Cracks tend to have a smooth fracture surface. RCP is affected by temperature, energy driving force, material, pipe size and processing efforts. We can test a variety of pipe diameters including 4”, 8”, 10”, 12” and 110 mm.

OEHHA Issues Proposed NSRLs for Three Disinfection By-Products
August 11, 2020
On May 22, the California Office of Environmental Health Hazard Assessment (OEHHA), which assesses health risks of environmental contaminants in products sold in California, issued three notices of proposed rulemaking (NPRs) establishing proposed no significant risk levels (NSRLs) for three water disinfection by-products : trichloroacetic acid, dibromoacetic acid and dichloroacetic acid; also known as haloacetic acids. These NPRs were open for comment until July 7. OEHHA is now reviewing the comments and will then issue a final rule.
