4. Why should I use only PROCEQ® EQUOTIP® Impact bodies?

Other manufacturers have created some confusion and uncertainty among our customers by promoting cheap repair offers for our impact bodies. Proceq's experience has been that such repairs greatly increase the probability of poor and inadequate test results. Several years ago PROCEQ had impact bodies that allowed for replacement of the impact ball by opening the impact body. These ball exchanges were intended to only be performed by PROCEQ specialists using replacement balls of a specific material, quality, and origin. Unfortunately, a lot of ball exchanges were performed by unauthorized companies and untrained personnel. When this occurred, ball material of an undefined origin and the improper mounting of those balls often led to a failure of the instrument to measure accurately with respect to specifications on our standard test blocks or, worse yet, later in production under actual test conditions. PROCEQ decided for these reasons (in the case of impact body D) to discontinue ball replacement and to use only permanently mounted impact bodies which in case of wear can be exchanged with a new impact body for a much lower price. This decision has resulted in a constant high durability and reproducibility for each exchange impact body. PROCEQ uses only materials of determined quality, exactly specified by PROCEQ, and each piece is subject to rigorous quality inspection prior to sale. Impact body D as currently delivered will be destroyed and useless when an improper attempt to open the body is made. Competitors and even former distribution partners are currently promoting to our EQUOTIP customers via Internet and other means this poor practice of ball exchange and of using cheap copies of impact bodies for use with our EQUOTIP. We can at this point only repeat and stress the fact that, for our EQUOTIP instruments, exclusively original parts and components of PROCEQ have to be used in order to maintain operation within PROCEQ specifications. If original PROCEQ parts are not used, the risk of the EQUOTIP to perform outside of PROCEQ specifications is very high. Be aware that impact bodies from China , Japan and Germany look at first sight very much like the original ones. But, the slight deviations in the tolerances of impact body mass, of the position and geometry of the permanent magnet, and of the different ball material cause negative effects on the accuracy of the hardness testing results. Even if the performance test of the instrument meets the specified value of the standard test block, large deviations from the standard (ASTM A 956-02) over the whole hardness range are to be expected. All with less durability (faster wear) when compared to the EQUOTIP impact device D. Please contact us for more technical information.

5. Why should EQUOTIP® Test Blocks not be re-surfaced?

Grinding or otherwise re-surfacing EQUOTIP test blocks to extend useable life is to be strictly avoided as it is not possible to expect homogeneity and suitability of the newly refinished surface. The refinishing process alters the dimensional tolerances, the microstructure, and the hardness. Thus the test block itself will be in violation of the specifications given in ASTM A 956-02. Most standards stress this fact explicitly and without reserve. The operating manual also stresses the importance of using original standard test blocks. The measuring base of the L-value is exclusively with PROCEQ SA which has made it possible to maintain a reliable, constant standard over more than 25 years. To obtain reliable, calibrated L-values, the calibration with PROCEQ's L-Standard is required.
