PART 2 - PRODUCTS

2.01 APPROVED MANUFACTURERS / SUPPLIERS

A. Lead Glass Pro • www.leadglasspro.com • e-mail: sales@leadglasspro.com, a recognized manufacturer / fabricator regularly engaged in the successful production of the products specified herein.

2.02 MATERIALS AND FABRICATION

X-Ray Lead Glass is an annealed, high density flat glass manufactured to glazing industry standards and provide the same shielding equivalent as the partition, wall or door wherein the X-Ray Glazing occurs. Each piece must be clearly labeled or identified as “X-Ray Lead Glass” and protective lead shielding thickness equivalency.

A. Thickness: 5/16” minimum in single layer or multiple layers as needed to obtain required shielding equivalent to meet lead thickness value in wall or partition that X-Ray Lead Glass occurs in.

B. Appearance: Clear with yellow hue due to radiation protective oxide and heavy metal contents. X-Ray Safety Glass, required at glazing locations in lead lined door vision lites or in side lites, borrowed lites or windows in wall locations within 24” of door openings, must be permanently labeled as impact resistant in compliance with ANSI Z97.1 and CPSC 16 CFR Part 1201 for impact resistance, as manufactured by Lead Glass Pro • phone: (800) 506-9972 • email: sales@leadglasspro.com • www.leadglasspro.com

C. Sizes: Single pane sizes up to and including 96” X 48” maximum, X-Ray Lead Glass must have a minimum density to provide proper shielding with no less than 60% total heavy metal oxide content and a minimum of 55% lead oxide content by weight.

PART 3 - EXECUTION 3.01 INSTALLATION

A. X-Ray Lead Glass must be carefully installed vertically into the lead lined frame per manufacturer's instructions. Window frame must be clean, square and plumb with 1/8” maximum space for clearance around the perimeter and allowance for appropriate seals, glazing tape or gaskets. Stops must be set snug but not too tight. Avoid pinching or unequal pressure points against X-Ray Lead Glass surfaces and edges.

B. Glass must be immediately cleaned and protected from damage by other trades or activities until the room is complete.

3.02 CERTIFICATION

A. Upon completion of X-Ray Lead Glass installation, Manufacturer / Fabricator shall furnish a certificate of compliance stating that all glazing materials are in accordance with this specification, the plans and the physicist shielding report for this project.

3.03 TESTING

A. After the X-Ray equipment has been installed and placed in operating condition but prior to occupancy and use, the radiation shielding shall be tested by the original calculating project health radiation physicist of record at Owner's expense.
