Additional Information

This model fully complies with the ASTM C140 Standard which specifies the minimum platens thickness related to the spherical seat bearing area and the specimen dimen­sions as shown in the sketch.
Min. platens thickness = d = A – DPL/2
A: distance from spherical seat centre to specimen corner
DPL: diameter of spherical seat bearing surface (see ASTM C140 Annex A8)
(see photo 9)


(To be specified at time of order: these items has to be factory installed.)
Serial printer for Automax testers
Upgrade of a PILOT or AUTOMAX system to incorporate a serial graphic printer in the front panel, allowing results (including a load/time plot) to be printed at the end of test

Second and third frame connection
The PILOT System can be upgraded with a hydraulic valve for controlling (not simultaneously) a second and third frame.
Note: when connecting a low capacity frame (i.e. flexural or cement) pressure regulator 65-L1400/X5 may be necessary. Please ask our technical department.
Two-way valve for PILOT System to control a second frame. This item must be factory installed.
Three-way valve for PILOT System to control a second and third frame. This item must be factory installed.

Special calibration procedure
Special calibration of compression testers assuring Class 1 (EN) and Class A (ASTM), from 1% to full load range.

Conversion set to test cylinders
This innovative upgrade is achieved by fitting the conversion apparatus, which consists of a rail sliding system and a 165 mm (6.5” ) diameter compression platen with a spherical seat, to the rear part of the frame.Once installed, the testing configuration can be changed with minimum effort: all that’s required is to loosen the central screw using the upper hand wheel, slide off the upper block platen with spherical seat and fit the cylinder spherical seat assembly.

Conversion set to test cylinders up to 6” x 12” to ASTM C39, comprehending spherical seat and upper compression platen dia.165 mm (6.5”) system for easy removal and repositioning of the upper block spherical assembly
