用大量测试数据表明：50％液碱的质量分数检测结果受温度、样品质量以及称量误差等因素的影响。当温度为15～40℃时，温度对其浓度影响较小；但当50％液碱结晶时，对第二方实验室来说，结晶部分不易检测，晶体越多，液态部分的碱浓度越低，50％液碱浓度的变化越大。
용대량측시수거표명：50％액감적질량분수검측결과수온도、양품질량이급칭량오차등인소적영향。당온도위15～40℃시，온도대기농도영향교소；단당50％액감결정시，대제이방실험실래설，결정부분불역검측，정체월다，액태부분적감농도월저，50％액감농도적변화월대。
The following conclusions were drawn from a large amount of test data .The mass fraction test results of 50 wt% caustic soda solution were influenced by temperature , unstable sample quality , weighing error , etc.The test results of 50 wt% caustic soda solution were less influenced by the temperature when the temperature ranged from 10 to 40 ℃.When the 50 wt% caustic soda solution crystallized , the part of crystal was not easy to test in the second party laboratory .The more the crystal , the lower the caustic soda concentration of the liquid part , and the larger the change of concentration of 50 wt%caustic soda solution .
