Lead X-Ray Safety Glass
Any x-ray control window within 24" of a door opening and any door lites must have impact resistant glass. Radiation Protection Products offers two types of leaded safety glass to meet the ANSI Z97.1 and CPSC 16 CFR 1201 codes. One using a 3M film and one using a laminate interlayer. Both methods are described below and both meet all applicable requirements.

3M Scotchshield™ Safety Film Solution:
Our 3M Film solution meets all applicable requirements including ANSI Z97.1 and CSPC 16 CFR 1201. The film utilized is 3M's 1/4" single clear Scotchshield Ultra Safety and Security Window Film. This film can be applied to all thicknesses of leaded glass including 1/16", 3/32" and 1/8". Once applied, the film allows our leaded glass to be utilized in door lites and site lites that occur within 24" of a door opening. This safety film can be applied to all sizes of glass up to a 48" x 36". With a film thickness of .05mm, the 3M film does not affect the overall nominal thickness of the leaded glass. One applied, the thicknesses for the following lead equivalencies will remain relatively unchanged: 1/16" lead equivalency = 5/16" physical thickness, 3/32" lead equivalency = 3/8" physical thickness and 1/8" lead equivalency = 1/2" physical thickness.

Safety Glazing Code
Category II Architectural Laminated Lead Glass (X-Ray Glass, Radiation Shielding Glass, Leaded Glass) meets category I and II requirements of the Consumer Product Safety Commission (CPSC) Federal Standard 16-CFR-1201. Additionally, the product complied with model building code safety standards for human impact performance as found in section 2703 of SBCCI Standard Building Code, and section 5406, Sections 54-2 of ICBO Uniform Building Code.
Frequently Asked Questions About Lead X-Ray Safety Glass
What certifications and safety standards does RPP's X-ray safety glass meet?
Our leaded safety glass meets ANSI Z97.1 and CPSC 16 CFR 1201 impact-safety requirements, covering both Category I and Category II, and it's available with either a 3M Scotchshield Ultra Safety Film or a laminated interlayer construction. It also complies with model building code standards for human impact performance under Section 2703 of the SBCCI Standard Building Code and Section 5406 of the ICBO Uniform Building Code. Any glass within 24" of a door opening, or used in door lites, needs to meet these codes.
What's the difference between the 3M film and laminate options for X-ray safety glass?
Both options meet ANSI Z97.1 and CPSC 16 CFR 1201. The 3M film applies a thin (.05mm) Scotchshield Ultra Safety Film over leaded glass at any of our standard lead equivalencies, without changing the glass's overall nominal thickness, and it's used mainly for door lites. The laminate option bonds leaded X-ray glass to a clear interlayer and a piece of clear float glass. The exact build varies by lead equivalency; our 1/16" laminate, for example, runs roughly 7.0mm leaded glass, 1.5mm interlayer, and 4.0mm clear float, for a finished thickness of about 1/2". Laminate tends to get chosen when a project needs to meet state specs requiring both safety and lead properties in the same panel.
Does safety-rated X-ray glass reduce visibility compared to standard lead glass?
Not in any meaningful way. Our 3M film safety option transmits 87% visible light, rejects 98% of UV light, and has only 2% glare reduction, with 11% visible light reflected, so visibility stays close to standard leaded glass while adding impact resistance.
When is impact-resistant X-ray safety glass required instead of standard leaded glass?
Any X-ray control window within 24" of a door opening, along with any door lite itself, must use impact-resistant glass meeting ANSI Z97.1 and CPSC 16 CFR 1201. Outside that zone, standard leaded glass may be sufficient, depending on your project's requirements. See our Leaded X-Ray Glass page for more on standard options.
