This document specifies a method for determining the pour point of petroleum products by means of automated equipment, in which movement of the test specimen is detected using a step-wise cooling technique. A separate procedure suitable for the determination of the lower pour point of fuel oils, heavy lubricant base stock, and products containing residual fuel components is also described. The…

This document specifies a test method based on a FZG four-square test machine to determine the relative load-carrying capacity of high EP oils defined by the gear surface damage known as scuffing. This test method is useful for evaluating the scuffing load capacity potential of oils typically used with highly stressed cylindrical gearing found in many vehicle and stationary applications. It is…

This document specifies a test method based on a FZG four-square test machine to determine the relative load-carrying capacity of lubricating oils defined by the gear-surface damage known as scuffing. High surface temperatures due to high surface pressures and sliding velocities can initiate the breakdown of the lubricant films. This test method can be used to assess such lubricant breakdown…

This document specifies the requirements and test methods for laminated products made of bamboo strips for indoor furniture purposes. It also specifies handling, storage, packaging and marking requirements.
