The full scale fire tests were conducted in the standard single room accorded with ISO 9705, whose inner dimensions are 3.6 m×2.4 m×2.4 m. Fire parameters such as the heat release rate and mass loss rate of the burning sofa and temperature profiles of inner room, have been measured. The relationships among the fire parameters were also studied.

A lot of laboratory tests and actual field concentration determinations showed that this meter could be easily operated and had a high sensitivity of 0 1mg/L and a linearity range of 0-100mg with an accuracy of 2% of the full scale on meter (in range of 20-60mg/L,the accuracy was 0 2mg/L).

Pathological findings strongly resembled the full scale of lesions in human CMV infections.

Both groups were in the average IQ range as measured by the Wechsler Adult Intelligence Scale, with LD males significantly higher on the Full Scale IQ and three out of the four subtests, Picture Completion, Block Design, and Information.

Based on the full scale predictions, it is suggested that the magnitude of flow velocities are technologically significant in terms of their effect on ferro-alloy immersion times and recoveries.

Reliability analyses indicate that the subscales and the full scale have high internal consistency.

The full scale of 32 items is called the Humiliation Inventory.
