Architects and designers rely on product data sheets to select and specify products.  But it is sometimes misleading when we see the accessibility symbol.  Sometimes all the symbol is informing may be that it is accessible if mounted at a certain height.  But sometimes the data sheet gives information that a product is accessible, but it may not be correct. Beware of just going by the accessibility symbol and assuming the product is accessible without researching further.
 
One example is this napkin dispenser.  The technical data sheet claims that it is accessible by using the universal symbol of accessibility and it even quotes the Standards which states:
