appendix a. iso standards for adhesives and grouts

Transcription

1 ISO installation material standards for mortars, adhesives, and grouts are more fully described in the following standards: Ceramic Tiles - Grouts and adhesives - Part 1: Terms, definitions and specifications for adhesives Ceramic Tiles - Grouts and adhesives - Part 2: Test methods for adhesives Ceramic Tiles - Grouts and adhesives - Part 3: Terms, definitions and specifications for grouts Ceramic Tiles - Grouts and adhesives - Part 4: Test methods for grouts Where ANSI installation material standards refer to mortars, ISO installation material standards refer to such mortars as either adhesives or mortar adhesives. ISO adhesive and grout classifications are designated using letters to identify chemical make-up and optional properties. Numbers are used to identify performance levels. ISO Performance Requirements for Adhesives C Cementitious Mortars C1: Normal Tensile bond strength of 72.5 psi (.5 N/mm 2 ) when tested per ISO curing parameters, including water immersion, heat aging, and freeze-thaw cycling. Twenty-eight-day tensile adhesion bond strength 0.5 N/mm 2 (72.5 psi) after 20 minutes open time. C2: Improved Tensile bond strength of 145 psi ( 1 N /mm 2 ) when tested per ISO curing parameters, including water immersion, heat aging, and freeze-thaw cycling. Twenty-eight-day tensile adhesion bond strength 0.5 N/mm 2 (72.5 psi) after 20 minutes open time. Note: A Tensile Bond Test quantifies the amount of vertical force required to pull a tile or stone from a given substrate after a prescribed period of time. This test can be performed both in the lab and at the jobsite. D Dispersion Adhesives (Mastics) D1: Normal Shear adhesion strength of 145 psi ( 1 N/mm²) when tested per ISO curing parameters, including heat aging. Twenty-eight-day tensile adhesion bond strength 0.5 N/mm 2 (72.5 psi) after 20 minutes open time. D2: Improved D1 performance plus additional shear adhesion strength of 72.5 psi ( 0.5 N/mm²) after 21-day air cure and 7-day water immersion; also shear adhesion strength of 145 psi ( 1 N/mm²) at elevated temperatures. R Reaction Resin Adhesives (epoxy or polyurethane) R1: Normal Shear adhesion strength of 290 psi ( 2 N/mm²) when tested per ISO curing parameters, including water immersion. Twenty-eight-day tensile adhesion bond strength 0.5 N /mm 2 (72.5 psi) after 20 minutes open time. R2: Improved R1 performance plus additional shear adhesion strength of 290 psi ( 2 N/mm²) after thermal shock testing. for Adhesives F Fast-Setting/Fast-Drying F: Fast-setting (cementitious) with a minimum tensile bond strength of 72.5 psi (.5 N /mm 2 ) achieved within 24 hours. Twenty-eight-day tensile adhesion bond strength 0.5 N /mm 2 (72.5 psi) after 10 minutes open time. F: Fast-drying (D2 dispersion adhesive/mastic) with a minimum shear bond strength of 72.5 psi ( 0.5 N/mm²) after 7-day air cure and 7-day water immersion; also shear adhesion strength of 145 psi ( 1 N/mm²) at elevated temperatures. 316 COPYRIGHT 2013 by Tile Council of North America

2 E Extended Open Time E: Extended open time extends the open time in which a tile can be laid into the adhesive without loss of minimum bond strength. This would extend the Open Time of a C1 or C2, D1 or D2 adhesive from 20 minutes to 30 minutes for a 28-day tensile adhesion bond strength 0.5 N /mm 2 (72.5 psi). T Thixotropic [Non-Slip/Non-Sag] T: Slip resistant adhesives must not allow a specified test tile sample applied on a vertical surface to slip more than (0.5 mm). S Deformability Transverse deformation is the ability of the mortar to accommodate movement between the tile and the substrate. S1: Normal Deformability 0.1 ( 2.5 mm) and <0.2 (<5 mm) S2: Improved Deformability 0.2 ( 5 mm) P Plywood Adhesion Bond Strength P1: Normal Tensile adhesion bond strength of 72.5 psi ( 0.5 N/mm²) after 28-day cure P2: Improved Tensile adhesion bond strength of 145 psi ( 1 N/mm²) after 28-day cure ISO Performance Requirements for Cementitious Grouts CG Cementitious Grouts CG1: Normal Abrasion resistance <0.12 in 3 (2000 mm 3 ) Flexural strength under standard conditions >362.5 psi (2.5 N/mm 2 ) Flexural strength after freeze-thaw cycles >362.5 psi (2.5 N/mm 2 ) Compressive strength under standard conditions >2176 PSI (15 N/mm 2 ) Compressive strength after freeze-thaw cycles >2176 PSI (15 N/mm 2 ) Shrinkage <3 mm/m Water absorption after 30 min <5g Water absorption after 240 min <10g CG2: Improved Meets CG1 criteria with either improved abrasion resistance, reduced water absorption or both as given below for Cementitious Grouts A Abrasion Resistance A: High abrasion resistance 0.06 cubic inch (1000 mm 3 ) W Water Absorption W: Reduced water absorption after 30 min 2g; reduced water absorption after 240 min 5g F Fast Setting (CG1 or CG2) F: Fast-setting with compressive strength in 24 hours under standard conditions >2176 PSI (15 N/mm 2 ) COPYRIGHT 2013 by Tile Council of North America 317

Always check with the grout manufacturer for chemical resistance to a specific chemical. 318 COPYRIGHT 2013 by Tile Council of North America
