Small‐angle neutron scattering (SANS) is a transmission method working in the angular range 0.4–6° (2θ). In this paper, silver behenate powder [CH 3 (CH 2 ) 20 COOAg] (referred to as `AgBE'), one of the very few materials featuring Bragg reflections in the angular range accessible to SANS instruments, is suggested as a possible new SANS wavelength calibration standard. In the past, this powder has been successfully tested as a calibration standard in low‐angle X‐ray diffraction. Results of new SANS wavelength calibration measurements performed with AgBE and with the traditional method of time‐of‐flight measurements are presented and compared with low‐angle X‐ray diffraction measurements.
