Flexible Cellular Polymeric Materials - Determination Of Hardness (indentation Technique)
出版:Standardiserings-Kommissionen I Sverige

专家解读视频
Gives three methods to determine the indentation hardness of flexible cellular materials: Method A (indentation hardness index), gives a single indentation measurement for laboratory testing; Method B (indentation hardness characteristics), gives information about the shape of the hardness indentation curve; Method C (indentation hardness check), quick procedure suitable for quality control testing. The methods only apply to latex, urethane foam and PVC foam of the open cell type.
