Several tests are performed on a microbial level. Testing plays a vital role in the approval of any material, whether it is a cloth or any plastic that needs to be used in a product. Antimicrobial surface testing ensures that a particular piece of fabric is usable or not. ISO 21702 is a specialized antimicrobial surface test that is performed for the measurement of any antiviral activity or presence on the non-porous and plastic surfaces.
ISO 21702 test is usually used in a number of ways by using different viruses based on the type and demand of the material. These viruses can be substituted on the customer's varied needs and for better results on specific materials as we all are aware of the immense usage of plastic in our daily lives. It created the need to improvise and add specialized tests just for plastic surfaces and non-porous surfaces.
The standard ISO 21702 method is specially designed to check the ability of plastic material. It tests not only the surfaces of the plastic material but also other types of materials that sustain similar kind of properties to plastics. This testing method is used to kill the virus that is in contact with the surfaces of the treated material. It is necessary to note that every ISO 21702 method of testing can only be performed over 24 hours after contact with the virus on the surface. One of the most common viruses used in the process is the Influenza A virus, Feline calicivirus.
ISO 21702 is one of the most popular and most requested surface tests on plastic materials. However, there are several measures to take while conducting such antimicrobial surface testing. For instance, UV exposure, humidity and usage of other agents that are released affect the efficiency of antiviral plastics. Antiviral plastics or antimicrobial plastics may or may not meet the requirements of the surface testing. However, when the process is conditioned in a specific stimulating environment, there are chances that the treated plastic may not continue to work as needed.
There are times when customers request the durability test of the plastic material in companion with the ISO 21702 test. In such scenarios combination of tests are performed to determine the product antimicrobial performance of the viruses when they are exposed to environmental conditions. These antimicrobial tests are very beneficial in providing quality products to the consumer.
