Gamma-ray bursts (GRBs) hold potential as standard candles for the high redshift universe. To help identify relationships which may arise in GRBs that could lead to a standard candle, isolated pulses from a number of very bright GRBs were inspected regarding their pulse scaling nature. A direct test of the pulse scale conjecture was conducted using energy channel data from the Burst and Transient Source Experiment (BATSE). The test consisted of taking a light curve for a bright GRB pulse from a specific BATSE energy channel, scaling it in brightness and time, and finding the best statistical fit for the same GRB pulse in a different BATSE energy channel. Many of the GRB pulses tested showed a statistically acceptable scaling between at least two BATSE energy channels.
