British Standards Institute BS AU251:1994
BS AU251:1994 was the first internationally recognised independent for windscreen
repair systems. The individual tests that make up BS AU251:1994 reflect the
requirements of rule EC43, the standard for windscreens. Therefore a repairs with
a system that has passed BS AU251:1994 can be considered equal to the original
glass. Esprit were the first windscreen repair company to pass BS251:1994. A
summary of our results is shown below.

Australian & New Zealand Standards AS/NZ 2366.2:1999
AS/NZ 2366 draws very much on BS AU251:1994 for its rules. The main difference is
a much more stringent set of test for long crack repair. Esprit passed the AS/NZ
2366 testing standards in 1999.
British Standards BS AU 242A:1998
This is not a performance test of windscreen repair equipment but a code of
practice that gives guidance on what can safely be repaired. The 1998 revision of
BS AU242a:1998 bought the standard into line with the Department of Transports MOT
test with regard to windscreen Repairs.
BS AU242a:1998 specifies that in order to carry out repairs that comply with its
guidelines, you must use equipment that has passed BS AU251:1994. The Esprit
system has done so, one of the many reasons that it is the system of choice of
most leading windscreen & replacement companies.
