Persistent Organic Pollutants (POPs) are chemical substances that are harmful to humans and exist in or accumulate within the bodies of animals and plants, and circulate in the natural environment over extended periods. POPs are naturally occurring or synthetic organic pollutants characterized by persistence, bioaccumulation, semi-volatility, and high toxicity. POPs include pesticides, industrial chemicals, and by-products unintentionally generated during industrial processes. These pollutants can travel long distances through various environmental media (air, water, organisms), crossing borders and affecting human health and ecosystems even in areas where POPs were never used or produced, causing significant global harm.

SVHC ,“Substance of Very High Concern”, refers to any substance that has adverse effects on human health and the environment.

PAHs Testing

California Proposition 65 (also known as Safe Drinking Water and Toxic Enforcement Act) was enacted as a ballot initiative in November 1986. Prop 65 businesses are required to provide a "clear and reasonable" warning before knowingly and intentionally exposing anyone to a listed chemical “Known to the State” to cause cancer or reproductive harm.

RoHS Testing

Phthalates is a general term for compounds that result from the reaction of phthalic anhydride and alcohol. Such substances are mainly employed as plasticizers making plastics and rubber more pliable. They are widely used in electronic and electrical equipment (EEE), toys, coatings, inks, garments, packaging materials, detergents, lubricants, and personal care articles. But when the concentration of phthalates exceeds a certain level, it may disrupt the endocrine system of human bodies, bringing harm to the development and health of children.

From small issues like paint peeling off phone cases or fading car buttons to major problems like outdoor equipment rusting and failing or electronic components short-circuiting, these seemingly "worn-out" problems often have a common culprit: environmental aging. Excessive humidity, sun exposure, salt spray corrosion, and high-temperature baking—products face environmental stress in real-world use that is far more severe than we might imagine. How can we predict a product's "anti-aging" capability in advance? Aging tests are a critical reliability assessment method. They simulate or intensify various conditions that a product might encounter in actual use, allowing for a quick evaluation of the durability, stability, and lifespan prediction of materials or products.

As wigs are consumer products that come into direct contact with the human head, their safety, durability, and realism have become core concerns for global market regulation. Different countries and regions have established strict regulatory standards for wig products, specifying multidimensional testing requirements that cover physical performance, chemical safety, and material identification. This article systematically outlines the main regulatory frameworks and core testing items in the wig industry to provide a reference for production and compliance.

Recently, the State Administration for Market Regulation (Standardization Administration of China) has approved the mandatory national standard - Provisions on the Limit of Harmful Substances in Watch Appearance Parts That Directly Contact Human Skin (GB 44702-2024), which was officially implemented on October 1, 2025.

The Restriction of Hazardous Substances (RoHS) in electrical and electronic equipment has evolved from a single European directive into a complex web of global regulations. For manufacturers and exporters, ensuring compliance across different markets is crucial but challenging. CIRS Testing offers a comprehensive, one-stop solution, providing expert RoHS testing and compliance services for all major international regulations, ensuring your products meet market access requirements worldwide.
