The boards are designed for flatness control using the “spot on paint” method and for precise marking work. They are used as supporting and mounting surfaces when assembling various machines and units.

The plates are made of cast iron and are divided into:

with manual scraping of working surfaces;
with mechanically processed working surfaces. The slabs are produced with a scraped, polished surface.

Control and measuring instruments (instruments) are equipment without which it is impossible to imagine modern production today. Measurements are required at every production stage and in a wide variety of industrial applications. That’s why the measuring instruments are so diverse, including calibration and marking plates (cast iron) GOST 10905-86, micrometers, mikators, calibration and measuring rulers, pedometers, inclinometers, thickness gauges, hardness gauges, microscopes, calipers, etc.

5. CONTROL METHODS

5.1. Verification of slabs - according to MI 2007.

5.2. The impact of environmental climatic factors during transportation is checked on a typical representative during periodic tests in climatic chambers. Tests are carried out after holding the slabs for two hours in each mode in climatic chambers at temperatures minus (50±3) and plus (50+3) °C and at relative humidity (95+3)%. After testing, deviations from flatness should not exceed the values according to clause 2.2.

After testing, deviations from flatness should not exceed the values specified in clause 2.2.

(Changed edition, Amendment No. 1).

5.4. Indicators according to paragraphs. 2.21-2.23 are confirmed during periodic tests based on the results of controlled operation of at least 10 slabs. The results of the controlled operation analysis are considered positive if:

2) the average value of the total service life of the slabs is at least 10 years (clause 2.21);

3) all controlled slabs will not reach the limit state within 5 years (clause 2.22).

(Introduced additionally, Amendment No. 1).
