GB/T22111 is a Chinese national standard that specifies the general requirements for environmental labeling products. This standard provides guidelines for the development and implementation of environmental labeling programs, including product certification, labeling criteria, and evaluation procedures.

GB/T22111 covers a wide range of product categories, including electrical appliances, electronic products, furniture, building materials, textiles, and chemical products. The standard also includes requirements for the use of environmental labels, such as the China Environmental Label (also known as the "Green Star" label) and the China Energy Label.

The goal of GB/T22111 is to promote the production and consumption of environmentally friendly products, reduce environmental pollution and waste, and enhance sustainable development. The standard is widely used in China by manufacturers, government agencies, and other organizations involved in environmental protection and sustainable development.

GB/T 22111 is a Chinese national standard for the "Test method for thermal conductivity of refractory materials by the heat flow meter method". This standard specifies the heat flow meter method for measuring the thermal conductivity of refractory materials at temperatures ranging from room temperature to 1600°C.

The heat flow meter method measures the thermal conductivity of materials by determining the heat transfer rate through a test specimen under steady-state conditions. This method is widely used for testing the thermal conductivity of various types of insulation materials, including refractory materials.

GB/T 22111 includes procedures for preparing the test specimens, calibrating the equipment, and conducting the tests. The standard also provides guidelines for calculating and reporting the results of the thermal conductivity measurements.

This standard is important in industries that use refractory materials, such as the steel and cement industries, as it provides a reliable method for measuring the thermal conductivity of these materials, which is a critical factor in their performance.
