注意事项/Points to note:

1. 根据执行标准的要求，所有试验设备和仪器都应进行校准和验证。

   According to the requirements of the standard, all test equipment and instruments should be calibrated and verified.

2. 选择合适的样品尺寸和形状，并按照标准要求进行制备。

   Select appropriate sample dimensions and shapes, and prepare them according to the standard requirements.

3. 在进行密度测试之前，确保样品表面干净，以避免任何污染对试验结果的影响。

   Before conducting the density test, ensure that the sample surfaces are clean to avoid any contamination affecting the test results.

4. 使用合适的方法测量样品的质量和体积，并计算密度值。

   Use the appropriate method to measure the mass and volume of the sample, and calculate the density value.

5. 在进行试验过程中，严格控制温度和湿度条件，以确保准确的密度测量。

   Strictly control the temperature and humidity conditions during the testing process to ensure accurate density measurement.

6. 对于不同形状和结构的样品，根据标准要求选择合适的测试方法和设备。

   For samples with different shapes and structures, select the appropriate testing method and equipment according to the standard requirements.

7. 在进行密度测量时，注意排除气泡和空隙，以确保测量结果的准确性。

   Take care to exclude bubbles and voids when measuring density, to ensure accurate measurement results.

8. 如果试验过程中出现异常情况或结果不符合预期，应及时记录并排除可能的干扰因素。

   If any abnormal conditions occur during the test or if the results do not meet expectations, promptly record and eliminate possible interfering factors.
