Voluntary Certification Program for Solid Surface Materials

International Cast Polymer Association
Voluntary Certification Program for Solid Surface Materials

ICPA endorses the following Voluntary Certification Program for Solid Surface Materials to assure consumers – from homeowners and builders to architects and remodelers – of the performance of solid surface materials they select and use.  Certified products have been tested and verified by a professional, independent laboratory to meet or exceed the requirements of ANSI/ICPA SS-1-2001, Performance Standard for Solid Surface Materials.The testing requirements described in this program are intended to evaluate the performance of solid surface materials according to ANSI/ICPA SS-1-2001Other authorities may have additional requirements for specific product types.

Qualification Inspection

Qualification inspection involves auditing the quality control program and random selection of product from the manufacturing facility’s finished goods inventory.  Solid surface material will be selected for testing to the entire ANSI/ICPA SS-1-2001, Performance Standard for Solid Surface Materials. Material selected will adequately represent the variety of materials the manufacturer produces and will include dark and light colored granite material, if available.

Quality Control Requirements

The manufacturing facility shall have a written quality control program that consists of the following:

  • Verification of the specifications of incoming raw materials through in-house testing and/or supplier provided documentation, and the maintenance of such records,

  • In-process manufacturing checks, such as color consistency and process control, with records of such checks and testing of the finished product on a regular basis.

The manufacturer's quality control program records will be audited by the independent testing authority.

Periodic In-Plant Inspections

Once a year randomly selected product will undergo a full series test.  Six months following the full series evaluation, randomly selected productwill undergo a short series test.  

  • Full series testing includes all sections of the ANSI/ICPA SS-1-2001. 

  • Short series evaluation includes the following sections of the ANSI/ICPA SS-1-2001:

    • Section 4.3.1 – Point Impact
    • Section 5.1 – Colorfastness and Aging Test
    • Section 5.2 – Stain Resistance Test
    • Section 5.5 – Heated Pan Test
    • Section 6.1 – Ability to be Renewed

Any change (other than minor adjustments) in the resins, fillers, catalyst, physical properties, or manufacturing process shall require testing in accordance with all sections of ANSI/ICPA SS-1-2001.  In the event of a failure, the manufacturer will be permitted two re-tests on randomly selected material. Three consecutive failures will cause certification to be suspended.  The manufacturer's quality control records will be reviewed and the calibration record of test equipment checked. 

Marking of Certified Product

A currently participating manufacturer may mark each product that passes the appropriate testing with a certification mark that would reference the ANSI/ICPA SS-1-2001 standard and HUD UM 104, subject to provisions of the independent laboratory’s licensing agreement.

Laboratory (Testing Agency) Requirements

  • Current Evaluation Report from Building Officials and Code Administrators, International Evaluation Service (BOCA-ES), International Conference of Building Officials Evaluation Service (ICBO-ES), Southern Building Code Congress International Public Safety and Evaluation Service (SBCCI PS&ES), National Evaluation Service (NES), International Association of Plumbing and Mechanical Officials Research and Testing (IAPMO R&T), National Voluntary Laboratory Accreditation Program (NVLAP), or American Association of Laboratory Accreditation (A2LA).

  • Ability to manage the inspection and testing process, collect and report data.

  • Willingness to compile periodic summary reports showing aggregated testing data for submission to ICPA.

  • Willingness to participate in inter-laboratory round-robin testing as needed.

  • Willingness to meet periodically with ICPA to evaluate trends in testing data and general improvements in the industry testing program or industry production practices that will help manufacturers meet or exceed the guidelines of the ICPA program.

  • Independence from ownership by or partnership with any other listing agencies or code bodies.
