Wall ties are manufactured to either BS1243 or DD140: Part 2: 1987 (Recommendations for the design of wall ties).

BS1243 refers purely to the shape and wire/strip sizes required for the manufacture of these ties.
DD140 requires the wall ties to have certain design characteristics to enable the designer to specify the correct type of wall tie for each situation.
Wall ties should be installed to the requirements of BS5628: The use of masonry: Part 1: 1992 which allows either BS1243 or DD140 wall ties to be used. This gives recommendations for embedment length of tie, density and positioning.
