GB 23463-2025 is an upcoming mandatory Chinese national standard for Protective clothing—Protective clothing against microwave radiation. It appears in the Consumer compliance cluster with a product safety focus and has an implementation date of Sep 1, 2026.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard specifies the technical requirements, marking, and manufacturer information for protective clothing against microwave radiation within the frequency range of 300MHz to 40 GHz. It is applicable to both reflective microwave radiation protective clothing (produced using metal fiber blending or fabric metallization) and absorptive microwave radiation protective clothing that uses absorbing materials to attenuate microwave radiation. It does not apply to protective clothing designed for frequencies outside the specified 300MHz-40GHz range.
Technical requirements
The standard outlines comprehensive technical requirements for microwave protective clothing. General requirements mandate that the clothing must not use exposed metal parts (like buttons or zippers) to prevent high potential differences and arcing in strong electric fields. The clothing must also be sealed in independent packaging with antioxidants to prevent oxidation of the metal layer. Structural and appearance requirements specify that clothing styles should be simple and practical, categorized into full-body, split-body, and local shielding types. For split-body suits, the overlap between the jacket hem and trouser waist must be greater than 20cm to minimize gaps. The core performance is defined by shielding effectiveness (SE), which is divided into 5 levels (Level I to Level V). The SE of the fabric must not be lower than that of the finished garment. For full-body suits, accessories like hoods and gloves must meet or exceed the main material's SE, while transparent eye shields must have an SE of at least 30dB. Additionally, the standard sets physical and chemical performance indicators for the fabric, including breaking strength, tearing strength, seam strength, and colorfastness to rubbing and washing. Manufacturers must ensure all these parameters are met to achieve compliance.
Testing methods
Testing methods include evaluating the shielding effectiveness (SE) of the finished garment using a specific test setup in a shielded room, as detailed in the normative appendices. The test utilizes a phantom man model (human body model) made of low-loss dielectric materials, with probes placed at the head, chest, and lower abdomen. Other tests follow referenced national standards: seam strength is tested per GB/T 21294, fabric breaking strength per GB/T 3923.1, tearing strength per GB/T 3917.3, and colorfastness per GB/T 3920 and GB/T 3921. The SE test requires measuring electric field strength with and without the protective clothing to calculate the shielding ratio.
FAQs
What products are regulated under GB 23463-2025?
GB 23463-2025 regulates protective clothing against microwave radiation in the frequency range of 300MHz to 40 GHz. This includes both reflective and absorptive types of protective clothing.
What are the key updates in GB 23463-2025 compared to the 2009 version?
The 2025 version updates the scope, adds terms like "microwave" and "phantom man model", changes the protection levels, updates the shielding effectiveness test methods, and adds a normative appendix for the general requirements of the human body model.
How is the shielding effectiveness (SE) classified in this standard?
The standard classifies SE into 5 levels (Level I to Level V) based on the decibel (dB) value. The fabric's SE must not be lower than the finished garment's SE, and specific components like transparent eye shields must meet a minimum of 30dB.
