This International Standard is intended for use when comparing friction materials under the same conditions

— dry thermal insulation

users can develop and assess relays and contactors to ensure the protection of the electrical systems from arc faults and overloads

BS EN 3971 is part of the series of EN metallic material standards for aerospace applications

Paper, board and pulps. Measurement of diffuse radiance factor (diffuse reflectance factor) not-for-sale This International Standard is intended1 Scope This International Standard describes the general procedure for measuring the diffuse radiance factor of all types of pulp, paper and board. More particularly, it specifies in detail in Annex A the characteristics of the equipment to be used for such measurements, and in Annex B the procedures to be used for calibrating that equipment. This International Standard may be used to measure the diffuse radiance factors and related properties of
