1、 Antibacterial performance testing of plastic coating products (applicable to antibacterial masterbatch system)

When antibacterial agents are applied to plastic products, they need to be evenly dispersed into the plastic product. Product processing factories often only have single screw machines and have no experience in dispersing antibacterial powder. We have made antibacterial plastic masterbatches that match the products, enabling product manufacturers to use them conveniently and safely.
When sampling antibacterial test samples, it is required that the antibacterial agent can be evenly dispersed on the sample. If uneven, it can lead to a decrease in antibacterial performance.

ISO 22196 Evaluation method for surface antibacterial properties of plastic products

This standard is an international standard, highly accepted in Europe and Japan, and also accepted by American manufacturers. European and American customers often choose this standard as the test basis
This standard has no basis for determining whether the antibacterial performance is met, and the test results need to be agreed with the customer.
Test sample requirements: plastic sheet, 5cm × 5cm, at least 4 pieces of each bacterium.

JIS Z 2801 Antibacterial Processed Products - Antibacterial Test Methods and Antibacterial Effects

This standard is a Japanese industrial standard and the earliest suitable standard for testing silver antibacterial materials, widely accepted by Japanese and European customers. On the basis of this standard
The ISO 22196 standard has been developed and formed. This standard has a judgment basis for the results of antibacterial performance testing, requiring that the logarithmic value of antibacterial activity be greater than 2.

QB/T 2591 Antibacterial Plastics - Test Methods for Antibacterial Properties and Antibacterial Effects

This standard is a Chinese light industry standard, which is the earliest suitable standard for silver antibacterial material testing in China and has been accepted by many domestic customers. This standard is formulated based on the JIS Z 2801 standard, and the content of mold prevention testing has been added. This standard has a judgment basis for the results of antibacterial performance testing and mold resistance testing.
Test sample requirements: plastic sheet, 5cm × 5cm, at least 10 pieces of each bacterium.


ASTM E 2149 Standard Test Method for Determining the Antibacterial Activity of Fixed Antibacterial Agents under Dynamic Contact Conditions

This standard is an American Society for Materials standard,
Test sample requirements: The weight of the product should be at least 5-10 grams, suitable for products that are easy to cut.
The antibacterial testing of coated products is consistent with the antibacterial testing standards introduced above.
For other standards, please contact our company.


2、 Antibacterial performance testing of fiber products (applicable to antibacterial finishing systems and antibacterial fiber systems)

ISO 20743 Determination of Antibacterial Properties of Antibacterial Finished Textiles

This standard is an international standard, highly accepted in Europe and Japan, and also accepted by American manufacturers. European and American customers often choose this standard as the test basis. This standard has no basis for determining whether the antibacterial performance meets the requirements, and it is necessary to negotiate with the customer to test the antibacterial performance requirements.
Sample requirements for testing: A minimum of 30 grams of product weight is required to test a bacterium.

JIS L 1902 Test Method for Antibacterial Properties of Textiles (Japanese Industrial Standard)

This standard is a Japanese industrial standard and a testing method for the static bacterial properties of textiles, widely accepted by Japanese and European customers. On the basis of this standard, the ISO 20743 standard has been developed and formed. This standard has a judgment basis for the results of antibacterial performance testing, requiring that the logarithmic value of antibacterial activity be greater than 2.
Sample requirements for testing: A minimum of 30 grams of product weight is required to test a bacterium.

Evaluation of AATCC 100 Antibacterial Fabric (American Association of Textile Printers and Dyers Standard)

This standard is a standard of the American Association of Preventive Printers and Dyers and one of the earliest quantitative testing standards for antibacterial performance, which examines the antibacterial performance of textiles. This standard is widely accepted by American customers. There is no basis for determining the antibacterial performance test results of this standard, and it is necessary to negotiate antibacterial performance requirements with the customer.
Sample requirements for testing: The weight of the product required for testing a bacterium should be at least 2 pieces of A4 paper size sample.

FZ/T 73023 Antibacterial Knitwear (China Textile Industry Standard)

This standard is a Chinese textile industry standard specifically designed for bacterial resistance testing of knitted fabrics. This standard is widely accepted by the domestic knitwear industry. This standard examines the dissolution of antibacterial agents and the washing resistance of antibacterial properties of antibacterial knitwear, and uses these two contents as the basis for evaluating whether the antibacterial performance is qualified.
Test sample requirements: For A-level testing, the required sample size is A4 plus 50 grams. For AA level testing, the required sample size is A4 plus 100 grams. For AAA level testing, the required sample size is A4 plus 150 grams.

GB/T 20944.2 Evaluation of Antibacterial Properties of Textiles - Absorption Method (Chinese National Standard)

This standard is a Chinese national standard and a testing method for the static bacterial properties of textiles. Similar to JIS L 1902, the evaluation standard for antibacterial properties is lower than that of JIS L 1902, making it suitable for domestic users.
Sample requirements for testing: The required product weight for testing a bacterium is at least 30 grams.

AATCC 147 Antibacterial Resistance of Textiles: Parallel Scribe Method (American Association of Textile Printers and Dyers Standard)

This standard is the standard of the American Association of Textile Printers and Dyers, and is the most classic qualitative testing method for antibacterial performance. It is widely accepted by European and American customers. This standard uses the presence or absence of antibacterial rings to determine whether its antibacterial performance is qualified. It is worth noting that there is no direct correlation between the size of the antibacterial ring and the strength of the antibacterial performance in this standard. If there is no bacterial growth at the bottom of the antibacterial fabric, it can be determined that the antibacterial test has passed.
