X-ray protection lead glass

The most critical factor is the Lead Equivalent (mmPb), which typically ranges from 0.5mmPb to 4.0mmPb depending on the radiation energy (kV) of the equipment. You must also verify the Light Transmittance, which should be above 85% to ensure clear visibility for medical staff. Additionally, check the density, usually required to be at least 4.2g/cm³ for high-quality radiation shielding.

For global trade, ensure the supplier provides CE marking for the European market and FDA registration for the U.S. market. The glass should comply with IEC 61331-2:2014 (Protective devices against diagnostic medical X-radiation) or ASTM C1036 standards. Always request a Radiation Shielding Test Report from a third-party laboratory to verify the lead content and attenuation properties.

Lead glass is primarily used in CT scan rooms, X-ray rooms, PET-CT suites, and dental clinics. During installation, it is vital to ensure a lead-lined frame is used to prevent radiation leakage at the edges. The overlap between the glass and the lead lining of the wall should be at least 10-15mm to maintain a continuous protective barrier.

High-quality lead glass should be free of bubbles, inclusions, or surface scratches, as these can impair visibility and indicate manufacturing flaws. Because lead glass is softer than standard glass, it is prone to oxidation (staining) if exposed to high humidity; therefore, look for suppliers offering moisture-resistant coatings or specialized polishing services.

The biggest risk is breakage due to the high density and brittleness of the material. You must mandate customized fumigated wooden crate packaging with internal shock-absorbing foam and 'Fragile' labeling. Furthermore, ensure the cargo is insured under All Risks (ICC A) terms to cover potential transit damage.

Focus on technical transparency. Ask for a video inspection of the factory's polishing and cutting process. Negotiate a staged payment plan (e.g., 30% deposit, 70% after passing a pre-shipment inspection). For large projects, request a sample piece (e.g., 100x100mm) to test the lead equivalence locally before committing to a full container load.

Utilize Secured Trading Services provided by Made-in-China.com to ensure your funds are protected until the goods are shipped. Always verify the supplier's Business License and Export Qualification to ensure they are a legitimate manufacturer rather than a small trading company without quality control capabilities.

Lead glass is often classified under HS Code 7003 or 7016. Be aware that some countries classify this as a medical device accessory, which may require the importer to have a specific Medical Device Import License. Check your local customs tariff schedule for anti-dumping duties that might apply to specialized glass products from certain regions.
