This draft amendment is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 162.

This draft amendment A1, if approved, will modify the European Standard EN 14325:2018. If this draft becomes an amendment,
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of
this amendment into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and
United Kingdom.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are
aware and to provide supporting documentation.

This document (EN 14325:2018/prA1:2022) has been prepared by Technical Committee CEN/TC 162

2 Modification to 4.4.2.1, General
Replace second and third paragraphs:
“There are three methods of leak tightness assessment, the pressure pot, the hydrostatic head and visual
inspection. The pressure pot shall be used if possible, but if not possible, the hydrostatic head test is
preferred. Alternatively, visual inspection shall be performed, if neither pressure pot nor hydrostatic
head test is performed. In this latter case, this shall be reported in the test report and also in the
Instructions for Use indicating that the visual inspection is qualitative and does not provide evidence of
liquid tightness after abrasion. If the assessment is performed through visual inspection, the maximum
classification that can be claimed is a Class 3.
Wherever possible the pressure pot method shall be used.”
by:
“There are three methods of leak tightness assessment, the pressure pot, the hydrostatic head and visual
inspection.
• The pressure pot shall be used for materials holding the pressure according to 4.4.2.2.
• The hydrostatic head shall be used for air permeable materials which cannot hold the pressure
according to 4.4.2.2, but can be tested according to 4.4.2.3.
NOTE 1 When evidence is presented that air permeable materials cannot hold the pressure according to 4.4.2.2,
this does not need to be re-confirmed.
• Visual inspection is permitted when the material does not permit either of the above quantitative
assessment methods in this subclause to be performed. In this case, this shall be reported in the test
report and also in the Instructions for Use indicating that the visual inspection is qualitative and does
not provide evidence of liquid tightness after abrasion. If this assessment is performed through visual
inspection, the maximum classification that can be claimed is a Class 3.
NOTE 2 When evidence is presented that neither of the above two quantitative assessment methods in this
subclause can be performed due to the nature of the material, this does not need to be re-confirmed.”
3 Modification to 4.4.2.2, Pressure pot end-point determination
Replace second sentence in 1st paragraph:
“Preferably the specimen’s exterior face of the fabric shall not be exposed to the pressure, if this is not
possible then reverse the face of the fabric prior to reverting to testing using the hydrostatic head.”

4 Modification to 4.4.2.3, Hydrostatic head end-point determination
Replace second and third paragraphs:
“The end point, i.e. the highest number of abrasion rubs which does not cause damage to the material,
shall be determined by the measurement of hydrostatic head method according to EN 20811 using a rate
of increase in pressure of (0,98 ± 0,05) kPa/min (or 10 cm/min). The hydrostatic head of the specimens
of the set of four test specimens prior to any abrasion shall be measured and the average hydrostatic head
for this set calculated. If the average hydrostatic head exceeds 200 mm, then the hydrostatic head method
is applicable and the leak tightness shall be determined as follows:
For each test specimen, the tested area of the abraded specimen is clamped into the hydrostatic test
apparatus and the hydrostatic head measured. If the average hydrostatic head of the specimens of a set
of test specimens exceeds 200 mm, a new set of specimens shall be abraded to a higher level of number
of rubs according to the levels of numbers of rubs in Table 1, until the level is reached at which the average
hydrostatic head is less than 200 mm. The highest level of number of rubs, at which the average
hydrostatic head is still above 200 mm, sh
