Part 3 of this European Standard specifies the requirements and tests for the construction, performance, safety and conformity of flow computers (FCs) used to meet the metrological and technical requirements of a high accuracy volume conversion device. They are used to determine volume of...
This part of IEC 61439 defines the specific requirements for public electricity network distribution assemblies (PENDAs). PENDAs have the following criteria: - used for the distribution of electrical energy in three phase systems for which the rated voltage does not exceed 1 000 V a.c. (see...
The mechanical test requirements for castings are given in the material specification in ASTM. Examples would be impact properties for grade LCC in A352, tensile strength requirements for grade 4N in A487, or ductility minimums for grade 70-40 in A27. The properties were developed for these...
5.1 The maximum energy input rate test is used to confirm that the dishwasher is operating at the manufacturer's rated input prior to further testing. This test would also indicate any problems with the electric power supply, gas service pressure, or steam supply flow or...
