| Keywords: LeatherResearch 009.jpg Designed primarily for the study of leather shrinkage this apparatus has been found of value for studying the high-pressure properties of a number of other high polymers Mounted in the press at left is a thick-walled cylindrical steel bomb which contains the polymeric specimen immersed in a pressure-transmitting liquid Pressure is applied to force a tight-fitting piston into the bomb from above This increases the hydrostatic pressure within compressing the specimen Depth of penetration of the piston is determined by reading the dial gage mounted on the ram that drives the piston into the bomb Connections to a manganin pressure gage which is mounted inside the bomb within the pressure-transmitting liquid may be seen near the bottom of the cylinder National Institute of Standards and Technology National Institute of Standards and Technology PD-USGov-NIST PD-USGov National Bureau of Standards National Institute of Standards and Technology Leather Leather shoes | ||||
