It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

These measurements are carried out in a climatic test cabinet where the temperature and humidity can be varied over a large range, so other conditions are also posible. Properties lengthwise and crosswise may be different if the composite is filled with fibres or flakes, which have been oriented eg during casting.

Standards Subsctiption may be the perfect solution. This standard does not purport to address all of the safety problems associated with its use.

Furthermore, DTI have experience with measuring the resistance of composites, rubber and textiles. This standard is also available to be included in Standards Subscriptions. The methods described above are not limited to measurements on polymer materials; they are also well suited for other materials with a comparable conductivity, ie.
