The fabric used to make this product has been tested and rated UPF 50+ according to tests done in an independent laboratory. UPF stands for Ultraviolet Protection Factor which tells a consumer how much of the sun’s UV radiation is actually absorbed. A fabric with a 50 rating will allow only 150th of the sun’s UV rays to pass through it.The tests done on our fabric were to the standards in accordance to the American Association of Textile Chemists and Colorists (AATCC) Test Method 183 and the American Society for Testing and Materials ASTM D6544 Treatment test. The AATCC 183 test defines the UPF rating of a fabric as the ratio of the UV measured without the protection of the fabric with protection of the fabric. Used in conjunction with this test, the AATCC 183 test then simulates the life cycle of that fabric. The UPF rating is then again determined after the end of the fabric’s life cycle – which is when most fabrics provide the most reduced level of UV protection. The method by which the UPF guidelines are based was developed and established in Australia in 1994. The Australian/New Zealand Standard for Sun Protective Clothing and Swimwear is now considered the industry standard in rating of all sun protective fabrics and clothing.
