The GB/T 44215-2024 standard specifies the test method for the deposition amount of the hot end lame plating solution on the inner surface of the Glass instrument. The standard details the principle of the test, the required reagents and materials, the instrument equipment, Sample Handling, the test steps, data processing, result representation and the requirements for the preparation of the test report. The test mainly involves extracting tin from the inner surface of the Glass instrument into the sodiumhydrate solution, and using Inductance Plasma Coupled Emission Light Spectrometer (ICP-OES), Inductance Coupled Plasma Emission Mass Spectrometer (ICP-MS) or Atomic Absorption Spectrophotometer (AAS) to determine tin. The standard applies to the quantitative detection of tin deposited in the hot end lame plating process on the inner surface of Glass instruments.
