Comparative Hardness Scales for Steel Table. Engineering Materials. Comparison of Hardness Scales: The following table compares the various hardness scales. Assumptions are that the metal tested is homogeneous to a depth several times that of the indentation. To the extent that the metal being tested is not homogeneous, errors are introduced ...
"As a rule, wood toilet seats are slightly more expensive than plastic toilet seats. Generally speaking, wood seats are thicker, warmer to sit on, sturdier, and more durable than plastic. Plastic lids are less durable & likely to show scratches -- even from soft sponges used when cleaning.
The wood toilet seat is much appreciated by individuals looking to create a more traditional but modernized look of a bathroom with a molded wood toilet seat or simply love the design a wood toilet seat adds to a bathroom.
I replaced a toilet seat. At they had a large selection of various materials - wood, plastic and molded wood. The old one was a molded wood seat that came with the house.
Wood toilet seats can withstand the same amount of weight and use initially as plastic seats can, but over time the enamel protecting the wood chips or becomes scratched. A well-made wood toilet seat can last several years, but if the lid is slammed frequently, scratches, dents and chips are more likely to occur.
3D Printing: How can I compare the hardness of ABS plastic and ...It's not just the hardness you need to worry about - oak is pretty hard - it's the vast physical difference between real wood and plastic. wood is cut from trees, which are a particular type of structure.
Durometer Shore Hardness Scale There are different Shore Hardness scales for measuring the hardness of different materials. These scales were invented so that people can discuss these materials and have a common point of reference.
Hardness may be defined as a material’s resistance to permanent indentation. The durometer scale was defined by Albert F. Shore, who developed a measurement device called a durometer in the 1920s. A chart showing general hardness comparisons is below.
hardness Most urethane products range in hardness, between 54a and 75d, on the durometer scale. The “D” scale is used to measure hardness greater than 95A.
The classic Oak wooden toilet seat Choosing the correct style With a focus on the look, it is important that the correct seat is picked in terms of design of the room.

Hardness comparison. There are a large number of hardness testing methods available (e.g. Vickers, Brinell, Rockwell, Meyer and Leeb). Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table e.g. for steels.

When it comes to installation and usability, wood and plastic seats are virtually identical, but plastic seats last longer. Because wood is a natural material, it eventually degrades in a high-moisture bathroom; solid wood seats discolor and the paint chips off of those made of medium-density fiberboard.
