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.

Specifications:

  • KING MASTER Test block meets ASTM E-10 standards.
  • All test measurement equipment is calibrated and traceable to NIST.
  • Test block dimensions (12″ square test surface): Length 6″ (15.24 cm), Width 2″ (5.08 cm), Thickness 5/8″ (1.59 cm)
  • Material: De-Carb free tool steel.
  • Brinell Calibrations: HB 200 – HB 500 (3000 kg).

Blocks are available in varying harndesses between 200-500 in approximate increments of 20HB
