Gauge Blocks Overview
Gauge blocks are precision tools essential for calibrating and setting up measuring devices, adhering to DIN EN ISO 3650 standards. The document categorizes gauge blocks into different accuracy grades:

• Accuracy Grade K: Utilized as a primary standard in laboratories.
• Accuracy Grade 0: Suitable for testing measuring devices and setting up high-precision gauges.
• Accuracy Grade 1: Used for testing check gauges and as a working dimension.
• Accuracy Grade 2: Applied for setting and working dimensions in production.

Material Properties
The document compares gauge blocks made from steel, tungsten carbide, and ceramic, highlighting:

• Coefficient of Expansion: Steel has the highest, tungsten carbide the lowest.
• Heat Conductivity: High in steel, low in tungsten carbide, very low in ceramic.
• Hardness: Tungsten carbide is the hardest, followed by ceramic and steel.
• Wear Resistance: Ceramic offers excellent wear resistance.
• Corrosion Resistance: Ceramic provides excellent resistance.

Permissible Deviations and Tolerances
A detailed table outlines permissible deviations (te) and tolerances (tv) for various gauge block sizes, as per DIN EN ISO 3650 standards.

Calibration
Gauge blocks can be supplied with a works calibration certificate or a DKD calibration certificate from an accredited laboratory. Special pricing is available for sets including these certificates.

Product Offerings
The document lists various gauge block sets and singles made from steel, tungsten carbide, and ceramic. Each block is marked with its nominal size and identity number, delivered in wooden boxes. Sets can be ordered with or without calibration certificates, with special compositions and accuracy grades available upon request.
