ISO 19712-2:2007

Overview

ISO 19712-2:2007 defines laboratory test methods for decorative solid surfacing materials - sheet goods. It specifies how to prepare specimens, perform tests and report results for the physical, aesthetic and durability properties of solid surfacing sheets (materials intended to be cast into sheets or shaped products). These test methods are primarily intended to be used with the product classifications and specifications given in ISO 19712‑1.

Key topics and technical requirements

ISO 19712-2 covers a wide range of property determinations and associated test procedures, including:

• Specimen preparation and cleaning - standard cleaning procedure and surface preparation before testing.
• Surface defects inspection - ink‑based visual inspection to detect cracks, pinholes, blisters and permissible blemish area limits.
• Consistency of colour - fabrication of seamed specimens and visual evaluation under controlled illumination to detect colour change along seams.
• Mechanical performance - load/deflection testing (unsupported panel loading) and impact resistance tests (including large‑diameter ball impact). Performance limits (e.g., residual deflection limits and absence of surface cracking) are specified.
• Durability and ageing - lightfastness (xenon‑arc exposure), resistance to dry and wet heat, hot/cold water cycling.
• Chemical and stain resistance - standardized staining/chemical exposure procedures and evaluation of cleanability.
• Other properties - resistance to cigarette burns, hardness (Ball indentation, Rockwell, Barcol references), and renewability (ability to repair/restore finish).
• Reporting requirements - prescribed content for test reports (product ID, deviations, results, date).

The standard references related test methods and instruments (e.g., xenon‑arc weathering, hardness standards) and aligns test conditions with end‑use performance.

Practical applications

ISO 19712-2 is used to:

• Verify product performance and manufacturability for solid surfacing sheet goods (countertops, benchtops, wall cladding).
• Support product specifications, material acceptance, QA/QC and contract compliance.
• Guide fabricators and installers on seam fabrication, finishing and expected in‑service behaviour.
• Inform material selection for applications requiring impact resistance, stain resistance, heat and light stability, and renewability.

Using these standardized tests helps manufacturers, specifiers and testing laboratories produce comparable, defensible performance data for commercial and architectural projects.

Who should use this standard

• Manufacturers of solid surfacing materials
• Independent testing laboratories and QA teams
• Fabricators, installers and contractors
• Specifiers, architects and procurement managers
