I've found this flat panel in my garden (1 x 1.5 meters, thickness approximately 0.5 cm): Is this Asbestos?
I'm in Bali where asbestos cement is still widely used. It's not friable.
You could order an Asbestos test kit online, and find out. The results are probably as accurate, if not more accurate than the answers you'll get from a random community of people on the internet.
I have no affiliation with PRO-LAB® or any of it's products, and do not recommend or endorse any of their products or services. This was simply the first product I found while searching the internet for "asbestos test kit"
