Since January 1979, CRT Laboratories, Inc. has been serving the industry by providing physical, mechanical and analytical services to both industrial and commercial clients. Our staff has extensive experience in testing a wide variety of Plastic, Composite and R&D products ranging from Homopolymer/Copolymer Blends, Unfilled/Filled Compounds, Carbon Fiber Composites, Laminate materials, Film/Packaging, etc. CRT Laboratories has complete Physical/Mechanical; Thermal/Infrared; Chemical/Product ID methods to further qualify materials. Our QC/QA Programs are among the finest and are ongoing with major firms such as DuPont, GE, Dow, Allied Signal, and 3M. CRT Laboratories provides complete testing of: pressure Pipe & Fittings, Faucets, Back-Flow Preventers, Flexible Water Connectors. We develop the technical writing standards for ASTM, BOCA, CSA, IAPMO, NES, NSF, and SBCCI. CRT Laboratories forensic and product examination techniques are state of the art. Staff members possess years of experience not only in polymeric science, but all production environments as well. With this experience, CRT Laboratories can relate to all aspects of the client's needs and understand concerns either from a raw material or production standpoint. CRT has also been instrumental in approval of structural properties of Fire-retardant-treated wood for City of LA and Underwriters Laboratories. CRT Laboratories is an active (certified/authorized) laboratory for the International Association of Plumbing and Mechanical Officials (IAPMO), which now offers a complete listing package "Listing Protocol Services" for potential IAPMO clients.

Physical & Mechanical Testing Laboratory: CRT Testing Capabilities

Partial Listing Only

CRT Laboratories maintains its own in-house Injection Molding, 2-Roll Milling/Compression Molding, Single/Twin Screw Extrusion and CNC/Wire-EDM allowing us to directly control each test specimen and compound produced. CRT can provide extensive information on process controls to meet your specific needs. These process controls are frequently audited for performance and improvements. Additional tests and Q.C. programs are available upon request. Shown below are just a handful of tests CRT performs on a daily basis:

IAPMO / NSF Requirements

CRT performs tests on all pipe, fittings, and plumbing fixtures to
ASTM, ANSI, ASME, IAPMO, CSA, ISO & many other standards

Plastic Pipe Testing

CRT Laboratories, Inc. offers a wide variety of pressure testing/analyses for Plastic Pipe and Fittings. CRT Laboratories has the capabilities to perform Hydrostatic Burst and Sustained Pressure tests in accordance with ASTM, AWWA, IAPMO, NSF, and all other applicable standards. CRT stocks four (4) complete pressure tanks to suit almost any need for pressure requirements. Pipe Sizes of up to 16" in diameter can be tested to temperatures up to 200°F, with pressures up to 5,000Psi. We have also added to our extensive list of plumbing tests, AWWA C-900 Pipe testing. With this service, manufacturers can list with IAPMO, CSA and NSF in a more- timely manner.

Elevated Pressure & Cycle Testing

CRT Laboratories, Inc. offers Elevated Temperature testing up to 230°F, with Cycle Pressures up to 4,000Psi. CRT tests to all applicable standards, and is able to design test equipment to suit any performance requirement (or newly proposed standard). CRT also performs Intermittent Shock Testing on Flexible Water Connectors (plastics, stainless steel, etc.). All equipment is calibrated to NIST (traceable) requirements and digitally controlled during the tests for precise control of all parameters.

Materials Testing Laboratory

CRT Laboratories, Inc. offers a wide variety of materials testing evaluation services. Our laboratory has extensive experience in evaluating competitor's products, as well as complete developmental services to qualify resins or compounds for production. CRT offers long-term accelerated analysis, equipment structuring/building and pre-qualification tests to meet your specific needs. A brief description of technical services we offer is shown below:

Environmental Stress Cracking Test

CRT Laboratories, Inc. offers ESCR analyses to qualify resins before full production. This service is applied to qualify many unfilled resins on today's market, and is a very good indication if a material is suitable for processing. CRT can perform ESCR Pressure testing (using Nitrogen/Igepal) to evaluate piping materials used for Gas or Cold-water distribution. CRT uses all applicable ASTM, IAPMO, and NSF standards for testing (unless otherwise specified), and can create newly proposed criteria to accommodate testing needs.

Injection Molding, Extrusion & 2-roll Milling

CRT Laboratories, Inc. offers Injection Molding of plastic materials ranging from un-filled to filled compounds. CRT maintains complete records of profiles during molding, and can supply those documents to the customer for reference. CRT also offers extrusion (single or twin screw) to evaluate new formulas or to pre-qualify resins. Equipment is fully calibrated and digitally controlled for maximum consistency. CRT can produce small batch compounds used for testing, or used internally for production. CRT has the capabilities of High-or-Low Load Compression & 2-Roll Milling of all plumbing compounds, including ABS, CPVC, PVC, PB, PE, PP, etc.

Failure Analysis Laboratory

CRT Laboratories, Inc. has extensive experience in problem solving of failed parts. Depending on the failure mode of the parts, CRT Laboratories will take accurate & economic steps to determine why the parts or raw materials have failed. This information can be presented in litigation and with the aid of qualified CRT staff we can assist your litigation process. CRT Laboratories also has expertise in Injection Molding and Extrusion (Ken Le Jeune), and may offer assistance to current on-the-floor problems, often due to in-proper drying, barrel profiles, mold temps, or improper material(s), etc. By having this experience in the lab, we can further pinpoint problem areas and prevent this occurrence from happening in the future. We encourage strong relationships with suppliers, molders, and compounders in order to solve problems faster and more accurate.
