23、001 (E) 1 Scope This European Standard sets the technical and functional characteristics for all types of thermometers (electronic, mechanical, etc.) for equipping the means used for the transport, storage and distribution of chilled, frozen, deep- frozen/quick-frozen food and ice cream and for meas
24、uring the internal temperature of the products. It specifies the test methods which allow the verification of the equipments conformity to suitability and performance requirements. It applies to the whole indicator-temperature sensor(s). The temperature sensor(s) may be integrated into the thermomet
25、er or remote from it (external temperature sensor(s). 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. F
