This standard is established as a specialized method for accurately determining the moisture content in polyamide (PA, commonly known as nylon) pellets and finished products -1-5-6. The standard provides two measurement methods, each applicable to different moisture content ranges: Method A has a determination limit of 0.1% or above, while Method B can achieve a determination limit of 0.01% or above -1-6. The standard explicitly states that it is not intended for measuring the equilibrium water absorption of materials but is designed for the precise detection of the actual moisture content in materials before processing -1-6. In relevant industry standards (such as those for recycled plastics), Method A is cited as the designated method for determining the moisture content of recycled polyamide -8. The recommended instruments for determination include the classic Karl Fischer titrator -8, as well as specialized differential pressure moisture determination devices (based on the principles of DIN EN ISO 960) -9.
