ISO1524 Scraper Fineness Meter

The scraper fineness meters produced by Jingke are manufactured according to the relevant provisions of the international standard ISO1524—1983(E), used for determining the fineness of color paints and related product particles. There are two types: single-groove and double-groove scraper fineness meters.

1. Specifications:

1. Scraper external dimensions

Length 175mm * Width 65mm * Thickness 13mm

2. Effective dimensions of the scraper groove

Length 140mm * Width 12.5mm

3. Scraper range scale values and recommended test fineness range:

	Maximum Range (um)	Minimum scale value (μm)	Recommended Range (um)
Single tank	100	10	40~~90
	50	5	15~~40
	25	2.5	5~~15
Double slot	100	10	40~~90
Double slot	50	5	15~~40

4. Squeegee external dimensions

Length 90mm * Width 40mm * Thickness 6mm

2. Accuracy:

1. Scraper precision

	Standard error of the marking line		Trench ratio error		Shape accuracy	Surface roughness	Note
	Range (um)	Error (um)	Ratio	Error (um)
Single tank	100	<2.5	1:1400	<2.5	Front Flatness tolerance 0.012	Front 0.1	The relative error of any point scale on the double-slot scraper should not exceed 1.2mm
	50	<2.5	1:2800	<2.5
	25	<2	1:5600	<2
Double slot	100	<2.5	1:1400	<2.5	Tolerance of transverse straightness 0.001	Trenches 0.2Ra=1.6
	50	<2.5	1:2800	<2.5

2. Scraper Precision:
Blade straightness tolerance 2μm, surface roughness Ra0.4

3. Notes

1. The front of the squeegee can be used for routine inspection of the straightness of the squeegee;

2. After use, wash the scraper thoroughly, apply anti-rust oil, and store it in the box;

3. The front of the scraper and the blade edge must not be bumped;

4. After one year of use, the scraper fineness meter should be calibrated at our factory once.

4. Quantity of scraper fineness gauges per set: one scraper and two squeegee blades.
