Introduction
With the development of society, advances in technology, photocatalytic materials and products increasingly wide range of applications. To protect the health of photocatalytic antibacterial industry
Development, the establishment of evaluation system, and regulate the production of business-related product quality, standardized access to markets and enhance international competitiveness, formulated standards.
This standard relates to antibacterial performance test methods and evaluation of photocatalytic materials and products for photocatalytic materials and other products of
Can such as self-cleaning, air purification, water purification and other test methods can refer to other relevant standards, this standard does not address.
In addition, long-term performance of photocatalytic antibacterial effect relates to many factors, the need for further research, this standard involves temporarily.
Photocatalytic antibacterial materials and products
Evaluation of antibacterial properties
1 Scope
This standard specifies the terms and definitions photocatalytic antibacterial materials and products antibacterial properties, evaluation of antibacterial properties, test methods and test
report.
This standard applies to antibacterial properties in the excitation light photocatalytic antibacterial materials and products, requirements, test sample surface is flat, and cover
Good contact with the cover film, the material may be glass, ceramics, plastics, coatings, fabric or the like.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
GB/T Total 4789.2 Microbiological examination of food hygiene colony assay
GB/T 6682-2008 analytical laboratory use specifications and test methods (ISO 3696. 1987, MOD)
3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Inhibit microbial growth and reproduction role, called inhibitory.
3.2
Having to kill microorganisms and vegetative propagules role called sterilization.
3.3
Both bacteriostatic and bactericidal effect, known antibacterial.
3.4
In certain light excitation, the resulting catalyst, called photocatalysis.
4 Evaluation of antibacterial properties
This standard specifies the test method according to the total anti-bacterial rate (R total) have been evaluated.
Antibacterial rate ≥90%, has an antibacterial effect;
Antibacterial rate ≥99%, with strong antibacterial effect.
Note. At the same time indicate the photocatalytic antibacterial contribution (R light) at 365nm light source on the report.
5 Test methods
5.1 Safety Tips
UV light source used in this test method has to eyes and skin damage, the operator must be careful! Note that the reactor should be closed,
Do not open when the light source directly observed with the eyes.
