Measuring Rules
The measuring rules based on the DIN 866 standard are high-precision measuring tools, made of stainless steel or other stable material, suitable for industrial and laboratory applications. This specification ensures straightness and graduation accuracy, ensuring reliable and accurate length measurements.
- Form A: Suitable for general use, with protection on both sides.
- Form B: Ideal for applications where measurement must start from an exact zero, with protection on one side.
These rules are an essential tool in metallurgy, mechanical engineering, and in fields where accuracy is critical.
Graduation accuracy and straightness of measuring rules according to DIN 866, Form A and B
Straightness refers to the lower measuring surface.
Form A – Measuring rule with 10 mm protective ends on both sides. Form B – The measuring rule starts from 0 on the left and has a 10 mm protective end on the right.
| Length a = mm | Form A Straightness (μm) | Form A Graduation accuracy (μm) | Form B Straightness (μm) | Form B Graduation accuracy (μm) |
|---|---|---|---|---|
| 500 | 35 | 30 | 70 | 75 |
| 1000 | 60 | 40 | 120 | 100 |
| 1500 | 85 | 50 | 170 | 125 |
| 2000 | 110 | 60 | 220 | 150 |
| 3000 | 160 | 80 | 320 |
