a) Structural, when applied to finishing technologies, refers to performance evaluation and characteristics.
3.3.1 Performance Evaluation
a) This section is designed to determine the performance of a finishing technology’s topcoat.
b) Finishing technologies not listed in the Performance Characteristics table below shall be tested in accordance with AWI Test Methodologies CR-1 and AR-1 (latest editions) to determine performance values.
3.3.2 Performance Characteristics
* Denotes finishing technologies identified by the Window and Door Manufacturing Association (WDMA) as applicable to doors addressed in ANSI WDMA I.S.1A and I.S.6A standards.
**TR - Transparent, OP - Opaque
AWI acknowledges the table above as historical data established through industry use of previous AWI standards. Furthermore, it is intentional that the revised reagent list in CR-1 test method varies from the list above in order to collect and establish new data, allowing for emerging technologies.
Notes for Performance Characteristics table:
Testing was evaluated in an ISO 9000-certified laboratory using the following ASTM test criteria: Chemical Resistance Testing - ASTM D1308 (latest edition), Wear Index - Abrasion Resistance Testing - ASTM D4060 (latest edition).
Baseline data for application prior to testing:
• 45-55% humidity at 70-80 degrees Fahrenheit
• Water-borne coatings must be cured in a dehumidified atmosphere and can be assisted with infrared light and good air movement.
Performance characteristic numbers are used, with the following definitions for chemical resistance and wear index - abrasion resistance:
5 - No effect from the test.
4 - Minimal effect or slight change and little repair required.
3 - Some effect; noticeable change, and the coating will recover with minimal repairs.
2 - Moderate effect, performance adversely affected and repairs required.
1 - Poor performance and film failure is imminent and repairs are difficult.
