Stone Product Standards

TSE	EN	UNI	ASTM
TS 699	1467	9725	C615-96
TS 1341 (prEN)	1468,1469
TS 6234	12507,12508

EN 1469 (Natural Stone Products Slabs for Cladding)

1. Thickness tolerances

The thickness shall not deviate from the nominal thickness by more than given in Table 1
Table 1

Nominal thickness (mm)	Tolerance
More than 12	± 10%
Up to and including 30	± 10%
More than 30	± 3 mm
Up to and including 80	± 3 mm
More than 80	± 5 mm

Stricter tolerances may be declared by the manufacturer. This is particularly important when the edges of the slabs will be visible.
NOTE: If the slab is to be fixed by adhesive or a thin mortar bed, stricter tolerances may be needed.
The required thickness of slabs shall result from a structural analysis or similar procedure which takes into account the technical and physical properties of the stone and the intended application.
For natural cleft/riven faces, Table-1 does not apply and the tolerances on thickness shall be declared by manufacturer.

2. Surface flatness tolerances

The deviation from flatness of the surface (except for natural cleft faces) shall not exceed 0,2 % of the slab length, and shall not exceed 3 mm. For natural cleft faces, the tolerance on flatness shall be declared by manufacturer.

3. Length and width tolerances

The length or width shall not deviate from t he nominal size by more than given in Table 2.
Table 2

Nominal length or width (mm)	< 600	>= 600
Sawn edges thickness <= 50 mm	± 1 mm	± 1,5 mm
Sawn edges thickness > 50 mm	± 2 mm	± 3 mm

Stricter tolerances may be declared by the manufacturer.

4. Tolerances for angles and special shapes

The permissible tolerance at any point shall be as stated in Table 2 (see Figure 1).
Each slab angle shall be in accordance with the agreed geometry. Pieces of special or irregular shape shall be checked for compliance with the required shape by use of a suitable template, the permissible tolerance at any point shall be as stated in Table 2.
Stricter tolerances may be declared by the manufacturer. This is particularly important when the edges of the slabs will be visible.

Physical Requirements

Physical Property	Test Requirements	Test Method(s)
Absorption by weight, max, %	0,40	C97
Density, min, lb/ft3, (kg/m3)	160 (2560)	C97
Compress., strength, min, psi (MPa)	19000 (131)	C170
Modulus of rupture, min, psi (MPa)	1500 (10,34)	C99
Abrasion resistance, min, HaA	25	C241
Flexural strength, min, psi (MPa)	1200 (8,27)	C880

The minimum compressive strength, flexural strength, and modulus of rupture shall be based upon the minimum average strength of specimens tested in for conditions;
◎wet 　　
◎dry 　　
◎parallel 　　
◎perpendicular to rift 　　
The physical properties given in Table represent properties of granite that have a history of successful use for general building and structural purposes. Granite with strength or abrasion resistance less than the minimum value prescribed in Table may be used provided that competent engineering authority has evaluated relevant characteristic of the granite. This evaluation shall consider both structure effects and material characteristics such as durability, permanent volume change, modulus of elasticity, thermal expansion, and the like.
