Previous studies at NIST on the use of ultrasonic extraction/anodic stripping voltammetry (UE/ASV) for determining lead in household paint found that the particle size of the ground specimen plays an important role in lead extraction efficiency
A series of measurements were made in the Al Mawqa/Al Ahmadi oil field region of Kuwait to explore the feasibility of assessing the heat release rate of individual well fires through flame height and thermal radiation measurements. The heat release rate
Life-cycle cost (LCC) analysis is an economic measurement technique used to determine the total cost of an investment project or activity over its lifetime. This Guide applies the principles of LCC to the special requirements of Environmental Management

In 1991 a series of 14 mesoscale fire experiments were performed to measure the burning characteristics of crude oil on salt water. These oil burns in a pan ranged in size from 6 m square to 15 m square. Results of the measurements for burning rate and
A series of measurements were made in the Al Mawqa/Al Ahmadi oil field region of Kuwait to explore the feasibility of assessing the heat release rate of individual well fires through flame height and thermal radiation measurements. The 12 fires measured
A literature survey was conducted to explore the need and appropriate systems for protecting elevator lobbies from smoke migration. The focus is on smoke spread through elevator shafts and lobbies, building occupant and fire fighter use of elevators during
