TESTING & MEASUREMENT New Directive Means


Tighter Controls on Metal and Steel Structures


A new directive for CE labelling of structural


steel products and their corrosion protection


will become effective in early 2014.


This means a shift


in product liability to the providers of the coating systems.


Life is about to change for manufacturers of metal and steel structures. For protection against the elements, all exposed steel parts have required an anti-corrosion coating such as hot-dip galvanisation. However, by 2014, a new CE labelling standard means that product liability will be significantly tightened and manufacturers will be obligated to verify the thickness of the hot-dip galvanisation. It will be the providers of the coating systems that will carry the burden of proof for docu- menting coating thickness measurements.


For many in this field, where the measurement demands can be many and varied, only the most user-friendly and cost-effective mea- surement technologies will come under consideration. The FISCHER MP0/MP0R product family meets precisely these needs and requirements. A compact design and simple four-button handling means these instruments are flexible in on-site applications and require no costly user training. The two displays allow for easy reading in various operational positions. Visual and acoustic signals inform the user when the measurement is complete.


Hard metal probe tips are a special feature that guarantees significantly longer lifetime, even on rough surfaces. Measurement results can be easily transferred to a computer for evaluation, recording and storage using the convenient FISCHER DataCentre software.

Meeting more demanding metrology requirements


Solutions are available for more demanding requirements, for example the measurement of hot-dip galvanised coatings underneath a layer of paint as shown in Figure 1. FISCHER’S FDX13H probe has been developed specifically for this purpose. Used in combination with the FMP instruments, it can determine the thickness of both the zinc and paint coatings in one “duplex measurement” step; the readings are

displayed separately. FISCHER has thereby succeeded in greatly simplifying for the user an extremely complicated metrology procedure, simultaneously presenting the results of two different physical measurement principles in one easy operation.
