It has come to our attention that clause 7.2.1.1, dot point 3 on page 11 of 17 is technically incorrect. It is not possible to unequivocally identify all fibre types using polarised light microscopy (PLM) as tremolite and anthophyllite have the same refractive index (1.6050). The Life Sciences ISO IEC 17025 Annex Asbestos sampling and testing has been revised to reflect this.
