This document stipulates a measuring method for the distribution of thickness, area mass, gas permeability and collection efficiency in the filter medium, and applies to both woven and non-wovenfilter medium.
This document provides a method for sampling specimen (position, size and number) from the filter medium required to obtain its performance distribution accurately.
The purpose of this document is to provide more accurate information about the morphology of the filter medium for users, and not to compare grade the performance of the filter medium.

This document specifies a manual reference method for the determination of the mass concentration of specific elements in stationary source emissions. The method is applicable to each of the specific elements in the concentration range of 0,005 mg/m3 to 5 mg/m3.
This document has been validated for the determination of the mass concentration of metals in incineration exhaust gases – applying the performance criteria stated in Clause 9 – for the following elements:
— arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), antimony (Sb), thallium (Tl), and vanadium (V) and their compounds.
The document can be used to determine metals other than those listed above (for example, selenium (Se) (ISO 17211), tellurium (Te), beryllium (Be) and tin (Sn)).
NOTE 1 These other metals mentioned above are commonly required by National Regulations, but this document currently has not yet been validated for these metals.
The document was validated for waste incinerators, but it is also applicable to other industrial processes, the practical experience shows that it can be applied over wide concentration ranges and various emission sources.
If mercury is intended to be determined as well, this can be sampled in a side stream arrangement of the sampling train (EN 13211) [5].
NOTE 2 This document has been validated with the described materials, equipment, sampling, and digestion performances etc., followed by analyses with AAS and ICP. This does not exclude the use of other types of equipment or analyses that meet the requirements and have been proven to be equivalent to the described European Standard.
