合成矿物纤维SMF澳洲要求
Synthetic mineral fibres (SMF), known also in the international literature as man-made mineral fibres (MMMF),MMVF and SVF, is a collective term used for amorphous vitreous fibres such as glass fibre, rock wool, slag wool, and refractory ceramic fibres (RCF), as well as the new low bio-persistent styles, which reflect all the SMF now manufactured in Australia.
The AIOH supports the continuance of the provision of guidance material and MSDS to define the safe handling practices for end users of products containing all forms of SMF.
The AIOH recognises that due to changes in the carcinogenic classification of some forms of SMF, the existing exposure standard based on respirable fibre numbers (0.5 f/mL) is not particularly appropriate to reflect the impact of upper respiratory tract irritation and hence a standard based solely on inhalable mass (2 mg/m 3 ) may be more appropriate for the low-bio-persistent forms of SMF. The existing NES (0.5 f/mL) should remain for some of
the old forms of SMF such as RCF.
What are synthetic mineral fibres (SMF)?
Synthetic mineral fibres (SMF, a specific Australian term) are a heterogeneous group of fibrous inorganic materials that contain various proportions of magnesium, calcium and aluminium, silicate and other trace oxides and metals, formed from a molten mass of rock, slag, clay or glass or synthetic ceramic mixes which are spun, blown or drawn into amorphous fibrous forms.
The overall classification of SMF is difficult and complex due to the diverse composition and forms which are designed to meet specific insulation purposes rather than fit into specific chemical/biological/toxicological groupings. The following graphic (IARC, 2002) is useful to understand the various categories of SMF. Other more complex classifications are also applicable (TIMA, 1991).
