Plastics laboratory ware -- Beakers
This standard was last reviewed and confirmed in 2015. Therefore this version remains current.
The requirements specify a series of plastic cylinders having a tapered ore non-tapered form. The capacity is in the range from 25 ml to 5000 ml. For non-opaque beakers the graduation is specified. The construction, dimensions and material are described. The annexes deal with the test for ionic material extracted by water and with the flexibility test.
