SASO ISO 13007 - Tile adhseive

Full form is

SASO = Saudi Standards, Metrology and Quality Organization

ISO = International Organisation for Standardisation

13007 series standard specifies the performance requirements and test methods for adhesives and grouts used in the installation of ceramic tiles. The standard categorizes adhesives into different classes based on their performance characteristics. 

Below is a table summarizing the minimum requirements for each class of adhesive as outlined in SASO ISO 13007:

Adhesive Class	Open Time	Slip Resistance	Shear Adhesion Strength	Tensile Adhesion Strength	Transverse Deformation
C1	≥ 20 minutes	No slip	≥ 0.5 MPa	≥ 0.5 MPa	Not required
C2	≥ 30 minutes	No slip	≥ 1.0 MPa	≥ 1.0 MPa	Not required
C2S1	≥ 30 minutes	≤ 0.5 mm slip	≥ 1.0 MPa	≥ 1.0 MPa	≤ 0.5 mm
C2S2	≥ 30 minutes	≤ 0.5 mm slip	≥ 1.0 MPa	≥ 1.0 MPa	0.5 mm
D1	≥ 20 minutes	No slip	≥ 0.5 MPa	≥ 0.5 MPa	Not required
D2	≥ 30 minutes	No slip	≥ 1.0 MPa	≥ 1.0 MPa	Not required
D2S1	≥ 30 minutes	≤ 0.5 mm slip	≥ 1.0 MPa	≥ 1.0 MPa	≤ 0.5 mm
D2S2	≥ 30 minutes	≤ 0.5 mm slip	≥ 1.0 MPa	≥ 1.0 MPa	0.5 mm

Notes:

Open Time: The duration during which the adhesive remains usable after application.

Slip Resistance: The maximum allowable slip of the tile after placement.

Shear Adhesion Strength: The adhesive's resistance to shear forces.

Tensile Adhesion Strength: The adhesive's resistance to tensile forces.

Transverse Deformation: The flexibility of the adhesive, indicating its ability to accommodate slight movements in the substrate.

C1

Normal cementitious adhesive

Basic performance (e.g., tensile adhesion strength ≥ 0.5 MPa)

C2

Improved cementitious adhesive

Higher performance (e.g., tensile adhesion strength ≥ 1.0 MPa)

D1

Normal dispersion adhesive

Basic performance

D2

Improved dispersion adhesive

Enhanced properties like water resistance, adhesion, etc.

R1

Normal reaction resin adhesive

Basic two-component adhesive

R2

Improved reaction resin adhesive

Better chemical and mechanical resistance

F

Fast-setting

Adhesive sets faster than standard time

T

Slip resistance

Adhesive prevents tile from slipping vertically

E

Extended open time

Adhesive maintains bonding strength for longer after application

S1

Deformable

Adhesive can flex ≥ 2.5 mm and < 5 mm (for moderate substrate movement)

S2

Highly deformable

Adhesive can flex ≥ 5 mm (used in areas with high movement or stress)
