yes. 5.1.3 As the results are accumulated during internal control and interlaboratory experiments, the quality indicators
of the results of measurements of the IC TG by the method according to this standard when it is implemented in a particular
laboratory can be refined taking into account the values actually provided by the laboratory.
- the price of the smallest category in units of mass fraction of moisture - 0.01%; - the
maximum weight limit - not less than 30 g; - the price of the
smallest category in units of mass - no more than 0.001 g; - limit of absolute
weighing error - no more than 0.005 g; - range of preset drying temperatures - not
less than 50 °C - 180 °C; - discreteness of the set drying temperatures - 1 °C.
5.1.2 In this section, the maximum characteristics of the TG IR error me
specified in Table 1 is provided by the IK TG moisture meter of an approved type with the following main characteristics:
industrial fertilizers and middlings for measuring instruments of a particular type are carried out in accordance with the
requirements of GOST 8.010, GOST 1.2, GOST 1.5 and this standard.
