The university team suggested that the best way to meet the requirements of Part M of the building regulations, which covers access for people, including those with disabilities, was to use coloured door handles. It said this would help the visually impaired as they were easier to pick out than reflective steel door handles.
The latest edition of Part M, which came into force in October, says architectural ironmongery ought to have colour and luminance contrast to the door.
Some guild members claimed that Turner's position, as the boss of a firm that manufactured coloured nylon door handles, was untenable as he would not be able to represent stainless steel hardware manufacturers.
The research is independent and carried out by academics. We’re standing by it

Turner said: "The research is independent and carried out by academics. We're standing by it." He noted that the researchers did recommend the use of some stainless steel door handles that were not coloured.
He also accused some door furniture makers of not facing the challenges of Part M.
Turner was elected as president in June 2003 for two years. He has been replaced by the vice-president of the guild, Arthur Taylor, commercial director of Hoppe, a manufacturer of metal door handles. Taylor will continue as acting president until the guild's annual general meeting in June, when an election will take place.
