Embodiment Construction

[0059] The invention provides a method for detecting uncertainty in the measurement of the heating loss of dibasic lead phosphite

[0060] step one, According to the method of heat reduction in HG / T 2339-2005 "Lead dibasic phosphite", weigh 10g of the sample of lead dibasic phosphite in a weighing bottle at 105°C ~ 110°C to constant weight, and move to In the oven, open the bottle cap so that the layer of the sample to be tested in the weighing bottle is at the same level as the mercury bulb of the oven thermometer, and the horizontal distance is not more than 100mm. Keep the temperature at 105°C-110°C for 1 hour, cover the bottle cap, and take out the weighing bottle. The measuring bottle was placed in a desiccator, cooled to room temperature, and weighed;

[0061] Step 2, the measured mathematical model

[0062] M(%)=

[0063] In the formula: m 0 ---Weighing bottle weight after constant weight (g);

[0064] m 1 --- Weighing bottle and sample weight before drying (...

Abstract

An uncertainty detecting method in heating loss measurement of dibasic lead phosphite is disclosed. The uncertainty detecting method includes: a first step of weighing 10 g of a dibasic lead phosphite sample to a constant-weight weighing bottle at 105-110 DEG C according to a heating loss method in HG / T 2339-2005 dibasic lead phosphite, transferring to a drying oven, opening a bottle cap, allowing the layer of the sample to be detected in the weighing bottle and a layer of a mercury bulb of a thermometer in the drying oven to be at the same horizontal plane and to have a transverse distance not more than 100 mm, maintaining the temperature at 105-110 DEG C for 1 h, closing the bottle cap, taking the weighing bottle out, putting into a dryer, cooling to room temperature, and weighing; a second step of determining a mathematical model to be detected; a third step of determining main sources of uncertainty; and a fourth step of determining values of components of the uncertainty.

Description

technical field [0001] The invention relates to a method for detecting uncertainty in the measurement of heating loss of dibasic lead phosphite. Background technique [0002] At present, the uncertainty in the measurement process is an index for evaluating the measurement level and a basis for judging the reliability of the measurement results. However, in the current prior art, there is a method for detecting uncertainty in the measurement of the heating loss of dibasic lead phosphite. Contents of the invention [0003] The invention provides a method for detecting uncertainty in the measurement of the heating loss of dibasic lead phosphite, which can measure the heating loss of dibasic lead phosphite by constant weight method at 105-110 ° C, and the measurement results The uncertainty was evaluated systematically, and the uncertainty evaluation method for this substance was established. [0004] The present invention adopts following technical scheme: [0005] The pres...
