The new set of British Standards are based purely on "performance" testing and do not include a specification (recipe) for the thermoplastic.However, many suppliers of thermoplastic still produce product to BS 3262 as there is still a demand for a standard, recipe based product amongst their customers.
This method of confirming quality of product still appears widely used in many countries around the world.
Many clients / specifiers still include a requirement for a basic specification for the formulation of road marking thermoplastic, and usually achieve this in one of two ways.
1) Include the BS 3262 formulation for thermoplastic, often without reference to BS 3262, as it is now withdrawn, although still widely quoted.
2) Specify a road marking thermoplastic to the current basic AASHTO formulation which is more or less accepted world wide, and is a stronger worded document than BS 3262.The thermoplastic is heated in one of the two heaters on the back of purpose built vehicle, when molten it is transferred to the holding tank on the "trolly" which is heated to maintain the thermoplastic in a molten condition.
