Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

Introduction
For installation of floor coverings, wood flooring and ceramic tiles, adhesives, thin bed mortars and
similar products are spread (combed) onto the substrate commonly using grooved (notched) spatulas
or trowels. The notches of the respective tools permit flow of the substance to be applied which will
then settle on the substrate in the form of strips (ridges). Consequently, the quantity of applied material
per unit area essentially depends on the geometry of the notches.

1 Scope
This document specifies the individual measurements of notches. It assigns specific codes used to label
notched tools according to the measurements and tolerances specified in this document.
2  Normative references
There are no normative references in this document.
3  Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1
notched trowel
notched spatula
rectangular or trapezoidal sheet steel, with evenly spaced grooves on at least one long side, commonly
designated as "notches"
Note 1 to entry: Normally, spatulas have a hand grip opposite the grooved (notched) side.
Note 2 to entry: The hand grip of a trowel is typically attached parallel to the sheet surface.
3.2
notched strips
rectangular, narrow sheet steel strips with evenly spaced grooves (notches) on one or both long sides
4 Shapes
Depending on the application and the desired ridge profile, notches can have a triangular, rectangular,
U-shaped or semi-circular shape.

c notch depth or groove depth
γ notch angle
Figure 1 — Different notch geometries
For manufacturing reasons, the inner points of the triangular notches and the inner right angles of the
rectangular notches are rounded off. The radius of curvature is 0,2 mm to 0,3 mm, on average 0,25 mm.
A special type of the triangular notch is the "pointed notch" with a bridge width "a" of 0 mm to 0,2 mm.
Other special types of notches with rounded off tops include U-notches, where the end of the notch is a
semicircle with a diameter of "b".
5  Tolerances
The tolerances of the dimensional specifications specified in Figure 1 are given in Table 1.

a ±0,1 mm
b ±0,1 mm
(a + b) ±0,1 mm
c ±0,1 mm
γ ±0,5°
6  Material
Depending on material hardness and thickness of the sheet steel, notched strips wear out more or
less quickly. Accordingly, notch area and consequently flow rate gradually decrease. To ensure long
durability of the notched strips, we recommend using spring steel with a minimum hardness of 46 HRD
or higher. Thickness of the sheet steel shall not fall below 0,5 mm.
