For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. Preparation of HG/T 3105 glass-lined steel specimens3 Test principleThe specimen is heated to a certain temperature, and then quickly put into cold water, observe the situation after quenching the specimen glass lining layer. If not destroyed, Successive raise test specimen temperature until the enamel coating damage so far. Appear before the destruction of a difference between the test temperature and the temperature of the glass is the sugar Abrupt changes in temperature difference value glass specimen.4 apparatus and instruments4.1 thermostatic oven Thermostatic oven shall meet the following requirements. a) the type thermostatic oven, basic parameters and dimensions shown in Figure 1 and Table 1. b) simultaneously heating furnace 3 specimens, the furnace temperature can be adjusted between 100 ℃ ~ 400 ℃ and to ensure that the temperature inside the furnace Uniformly constant at any set temperature. c) with a measurement specimen temperature and the temperature of the heating element near the sensor insertion port. d) guaranteed the specimen can be quickly put into cold water structure. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 7987-2013_English be delivered?Answer: Upon your order, we will start to translate GB/T 7987-2013_English as soon as possible, and keep you informed of the progress.
