The main changes at a glance
A new version of the international ISO 376:2011 standard for calibrating force transducers has become effective on January 1, 2012. What are the implications for you as a user? To make this conversion as convenient as possible for our customers we have summarized the main changes for you. Table 1 gives a first overview.
Table 1: Overview of changes in the new ISO376:2011
There have been no changes to the basic procedure, time frame and ambient conditions as stipulated in ISO 376 (table 1). However as an alternative, decreasing measurement series and therefore determining the hysteresis can be dispensed with. Instead, creep is now determined and considered as a new classification criterion. This results in four potential classification cases; table 2 shows which property is taken into account in which case. Case D enables direct comparison with the data provided in the previous calibration certificate and is relevant to the later use of the force transducer for calibrating material testing machines.
