4 Requirements
4.1 General
For any material, preformed sterile harrier system or sterile harrier system, the requirements of EN ISO 11607-1 shall apply.
Polyethylene and polypropylene non-wovens have different specific performance requirements and this shall be considered during design and use of stenle barrier systems for specific applications.
This part of EN 868 only introduces performance requirements and test methods that are specific to the products covered by this part of EN 868 but does not add or modify the general requirements specified
In EN ISO 11607-1.
As such, the particular requirements in 4.3 can be used to demonstrate compliance with one or more but not all of the requirements of EN ISO 11607-1.
NOTE Compliance to EN 868-9 does not automatically mean compliance to EN ISO 11607.1.
A confirmation of compliance to EN 868-9 shall contain a statement whether EN ISO 11607-1 is covered.
4.2 Materials
The uncoated material shall be translucent or opaque and made of continuous filaments of polyolefines of a high level ol’ purity and shall not release any substances in such quantities as could constitute a health risk
NOTE Attention is drawn to EN ISO 10993-1.
Conditioned material for testing shall comply with the test sample conditioning requirements of EN ISO 11607-1:2017, Clause 4.
4.3 Performance requirements and test methods
4.3.1 General
4.3.1.1 No colour shall leach out of the material. Compliance shall be tested by visual examination of a hot extract prepared in accordance with the method given in ISO 6588-2 modified to test temperature of (60 ± 5) °C.
4.3.1.2 The average mass of 1 m2 of the conditioned material when tested in accordance with EN ISO 536 shall be within ± 7 % of the nominal value stated by the manufacturer.
4.3.1.3 The internal tearing resistance of the conditioned material shall he not less than 1 000 mN in both machine and cross directions when tested in accordance with EN ISO 1974.
4.3.1.4 lIthe nature of the material allows a delamination to be initiated, the delamination factor of the conditioned material shall be not less than 1 N/25,4 mm when tested in accordance with
ASTM D2724.
4.3.1.5 The air permeance of the conditioned material shall be not less than 1 pam/Pa s at an air pressure of 1,47 kPa when tested in accordance with Iso 5636-3.
NOTE This requirement can be ignored for materials solely for use in irradiation sterilization packaging.
4.3.1.6 The resistance to water penetration of the conditioned material shall be determined using the hydrostatic head test based on EN ISO 811. Test results and test conditions shall be documented.
4.3.2 Specific performance requirements and test methods
4.3.2.1 Polyethylene based materials
4.3.2.11 The tensile strength of the conditioned material shall be not less than 4,8 kN/m in the machine direction and not less than 5.0 kN/m in the cross direction when tested in accordance with EN ISO 1924-2.
4.3.2.1.2 The bursting strength of the conditioned material shall be not less than 575 kPa when
tested in accordance with EN ISO 2758.
4.3.2.2 Polypropylene based materials
4.3.2.2.1 The tensile strength of the conditioned material shall be not less than 2,5 kN/m in the machine direction and not less than 1,5 kN/m in the cross direction when tested in accordance with
EN ISO 1924-2.
4.3.2.2.2 The bursting strength of the conditioned material shall be not less than 400 kPa when tested in accordance with EN ISO 2758.
4.4 Marking of the protective packaging
The protective packaging shall be legibly and durably marked with the following information:
a) reference, stock or catalogue number;
b) quantity;
c) the manufacturer’s or supplier’s name or trade name, and address;
d) date of manufacture in accordance with ISO 8601;
e) lot number1
f) nominal mass in grams per square metre;
g) nominal sheet size in millimetres or nominal width of rolls in millimetres and length in metres;
