King Master Brinell Test Block

Description

Unique patented electro-etched surface layout grid ensures proper spacing between impressions. Five master Brinell impressions are clearly identifiable.

Manufactured from de-carb free tool steel. Meets ASTM E-10 specifications

Aluminium test blocks available for lower harndess ranges.

Features:

• Unique electro-etched surface layout grid ensures proper spacing between indentations, makes full use of test surface and helps eliminate errors or improper positioning by targeting test locations.
• 5 master Brinell impressions are clearly identifiable, certified in accordance to ASTM E-10, on equipment calibrated and traceable to NIST.
• The arithmetic mean of these 5 impressions is inscribed on the block both in BHN Hardness and diameter in millimeters.
• Master impressions are made by a Brinell tester with oil dampened dead-weight electronically controlled cycle to insure uniformity of testing.
• Master impressions are calibrated using the most advanced optical calibration equipment available.
• Diamond polished reflective surface finish is grain free for ease of reading even in dark areas.
