WebPerspiration, also known as sweat, is the fluid secreted by sweat glands in the skin of mammals. [1] Two types of sweat glands can be found in humans: eccrine glands and apocrine glands. [2] The eccrine sweat glands are distributed over much of the body and are responsible for secreting the watery, brackish sweat most often triggered by ... WebComposition B softens at around 70oC, begins to melt at 79.6oC and has a cook-off threshold of nearly 180 oC 1. Currently there are no standard tests that can be used to assess the behaviour of Composition B filled munitions in a simulated hot-gun condition2.
