Test Pack History:

The Standard Test Pack origin lies back in 1963.  It was developed by in by Dr J Bowie and Mr J Dick in Bristol, UK and published in the 'Lancet' journal.

The Bowie and Dick type test pack was made from 29 to 36 huckaback linen type towels. Each towel was folded in half four times then stacked to a height of approximately 270mm high (10.5in). An A4 size sheet of paper with chemical indicator tape in the pattern of a diagonal St. Andrew's cross was placed horizontally in the center of the pack.  

In late 1970, 100% cotton surgical towels were introduced as an alternative to the huckaback towels.
Pre-printed chemical indicator sheets was also developed as an alternative to the St. Andrews' cross.

Alternative forms of the Bowie and Dick test:

Re-useable perforated plastic sheets with pre-printed center paper sheet
Single use paper packs with pre-printed center paper sheet
Re-useable electronic devices

Although other forms of devices are available, not all are able to be used for all purposes, so the Standard Test Pack remains the the most versatile.
