EN 13704 Hygiene Plastics Resistance to Bacillus Testing

The European Standard EN 13704 specifies a procedure for determining the resistance of hygiene plastics to contamination by the spore-forming bacterium Bacillus subtilis var. niger. This test is crucial in ensuring that materials used in hygiene products, such as medical devices and personal care items, maintain their integrity and sterility under real-world conditions.

The standard requires that samples are exposed to a suspension of the bacterium for an extended period (typically up to 90 days). During this time, the bacterial spores can adhere to the surface of the plastic material. The specimens are then subjected to a series of cleaning procedures as per the intended use. Post-cleaning, the presence and viability of Bacillus subtilis var. niger on the sample surfaces are evaluated.

This test is particularly important for ensuring that hygiene plastics do not become vehicles for pathogenic microorganisms during their lifecycle. By adhering to EN 13704, manufacturers can ensure compliance with regulatory requirements and provide consumers with a safer product.

The procedure involves several steps:

Preparation of the Bacillus subtilis var. niger suspension in an appropriate medium.
Application of the bacterial suspension to the surface of the plastic specimens.
Cultivation and incubation of the samples under controlled conditions for up to 90 days.
Removal of the specimens from the bacterial environment after incubation.
Performance of cleaning procedures as per intended use.
Evaluation of the remaining microbial load on the specimens post-cleaning.

The test results are reported based on the level of contamination and viability of the Bacillus subtilis var. niger. Compliance with this standard ensures that hygiene plastics can withstand real-world conditions without becoming a vector for harmful microorganisms.
