scope:

Procedures for preparation of fluorescent lamps for Toxicity Characteristic Leaching Procedure (TCLP) are presented below. These guidelines are intended to supplement the TCLP by supplying specific instructions for size reduction of lamps including integral electronic compact, pin-based compact, linear and U-shaped fluorescent lamps

This standard specifically covers integral electronic compact, pin-based compact, linear and U-shaped fluorescent lamp types. Additional standards have been prepared and are in preparation for high intensity discharge lamps, and other lamp types that require specific sample preparation instructions because of their design or construction. It consolidates and supersedes the following four NEMA standards: NEMA LL 1-1997, Procedures for Linear Fluorescent Lamp Sample Preparation and the TCLP; NEMA LL 2-1997, Procedures for Pin-Based Compact Fluorescent Lamp Sample Preparation and the TCLP; NEMA LL 5-1999, Procedures for U-shaped Fluorescent Lamp Sample Preparation and the TCLP; and NEMA LL 6-1996, Procedures for Integral Electronic Compact Fluorescent Lamp Sample Preparation and the TCLP.

The protocol that follows is grouped to include general requirements, safety considerations, lamp preparation, leaching, filtration, storage, and leaching vessel reuse.
