The reason why they're mentioning the "when" on the tests is that IQ tests are obviously not perfect, and fluctuate a lot when taken at young ages, generally skewing upwards. But I'm sure you knew that.
The minimum accepted age (I looked it up this time around) is 2 for the Stanford-Binet. The best yield is generally around 5-7 years of age. Much older and it stops becoming about intellectually driven actions and more about thought driven actions.
I think I was around 6 when my parents dragged me in to take it.
