^aStandard uncertainties (u) are u(T) = 0.20 K, u(NaCl) = 1 mmol kg⁻¹, u(urea) = 2 mmol kg⁻¹, u(thiourea) = 2 mmol kg⁻¹ and u(p) = 5 kPa (level of confidence = 0.68). Relative standard uncertainties (u_r) are u_r(cmc/cmc^id) = ±3%, $u_r(X_1^{\mathrm{m}}/X_1^{\mathrm{id}})=\pm 3\text{\%},$ u_r(β^m) = ±3% and $u_r(f_1^{\mathrm{m}}/f_2^{\mathrm{m}})=\pm 4\text{\%}$.
