another test - a really really important one - is to make a long rectangle (35mm high x 5mm x 10mm would probably do) - the height is important - then clamp one end to a desk. on the other end suspend a weight tied with string as close to the end as possible. make the weight... let's say.... 0.5kg or so. not very much. now leave it for a month.
