fibres (method using concentrated sulphuric acid)
33 Method 17. Binary mixtures of asbestos and certain
fibres (method based on heating to 450 deg C)
34 Method 18. Binary mixtures of chlorofibres, certain
modacrylics, certain elastanes, acetates,
triacetates and certain other fibres (method using
cyclohexanone)
