ISO 1524-2013 pdf download.Paints, varnishes and printing inks – Determination of fineness of grind.
ISO 1524 specifies a method for determining the fineness of grind of paints, inks and related products by use of a suitable gauge, graduated in micrometres.
It is applicable to all types of liquid paints and related products, except products containing pigments in flake form (e.g. glass flakes, micaceous iron oxides, zinc flakes).
Of the three gauges referred to in 4J., the 100 urn gauge is suitable for general use, but the 50 .tm and especially the 25 pm gauge will only provide reliable results in the hands of skilled laboratory personnel. Particular caution is necessary in interpreting readings of less than 10 urn.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 4618 and the following apply.
3.1 fineness of grind
reading obtained on a standard gauge under specified conditions of test, indicating the depth of the groove(s) of the gauge at which discrete solid particles in the product are readily discernible
4 Apparatus
4.1 Gauge, consisting of a block of a hardened steel e.g. 175 mm long. 65 mm wide and 13 mm thick At least for use with water-dilutable paints, a block of stainless steel should be used.
The top surface of the block shall be both plane and ground smooth and shall contain one or two grooves approximately 140 mm long and 12,5 mm wide parallel to the longer sides of the block. The depth of each groove shall be uniformly tapered along its length from a suitable depth (for example 25 pm, 50 pm or 100 pm) at one end to zero at the other end and shall be graduated as specified in Table 1. A diagram showing two typical gauges is given in Figure 1.
4.2 Scraper, consisting of a single- or double-edged steel blade approximately 90 mm long. 40 mm wide
and 6 mm thick The edge(s) on the long side(s) shall be straight and rounded to a radius of approximately
0,25 mm. A drawing of a suitable scraper is shown in Figure 2.
The scraper shall be periodically checked for wear, damage or warpage. Reject the scraper if inspection reveals damage.
The top surface of the gauge may be used for routine checking of the scraper, provided it itself is not worn or warped.
The scraper shall be handled and stored with particular care.ISO 1524 dpf download.
