Plastic materials. Determination of the ultimate aerobic biodegradability under controlled composting conditions. Method by using analysis of evolved carbon dioxide. Part 1. General method
State system for ensuring the uniformity of measurements. State primary standard and all-union verification schedule for means measuring heat conductivity of solid bodies in the range of 0,1 to 5 W/(m.K) at temperatures from 90 to 500 K and in the range from 5 to 20 W/(m.K) at temperatures from 300 to 1100 K
