EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 28927-7 testing. ISO 28927-7 specifies a laboratory method for measuring hand-transmitted vibration emission in the arms of hand-held, power-operated cutters and shears. It is a type testing procedure to determine the magnitude of vibration in the grip areas of a machine operating under specified test conditions. The results are intended to be used to compare different models of the same type of machine.
ISO 28927-7 is applicable to cutters and shears, driven by pneumatic or other means, designed to cut sheet or composite materials.
The vibration test codes for portable hand-held machines given in ISO 28927 are based on ISO 20643, which gives general specifications for the measurement of vibration emission of hand-held and hand-guided machines. ISO 28927 specifies the operation of machines under type-testing conditions and other requirements for the performance of type-tests. The structure/numbering of its substances conforms to that of ISO 20643.
The vibrations produced by nibblers and shears have been found to vary considerably in typical use. Variation is largely due to changes in machine use and the properties of the material being worked on, while differences in the support of the material also cause differences in vibration.
To provide a method that ensures good measurement repeatability, this part of ISO 28927 uses a working process in which the machine is used to cut sheet metal. It is important that the sheet is well supported and that the punches and cutting blades used are in good condition. ISO 5349 procedures are required when workplace exposure needs to be assessed.
