35、gh temperature.The test method described in this part of ISO 12127 allows this heat transfer to be assessed when a heating cylinder and the clothing material are brought into contact with each other.This part of ISO 12127 forms part of a series of standards concerned with clothing designed to protec

37、is part of ISO 12127 specifies a test method for the determination of contact heat transmission. It is applicable to protective clothing (including hand protectors) and its constituent materials intended to protect against high contact temperatures.Application of this part of ISO 12127 is restricted

38、 to contact temperatures between 100 C and 500 C.2 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.2.1contact forceforce acting on the test specimen and the calorimeter when they have been brought into contact with the heating cylinder2.2contact temp

The heating cylinder is lowered onto the test specimen supported by the calorimeter or, alternatively, the calorimeter with the specimen is lifted up to the heating cylinder. In either case, the operation is carried out at a c

The threshold time is determined by monitoring the temperature of the calorimeter.INTERNATIONAL STANDARD ISO 12127-1:2015(E) ISO 2015 All rights reserved 1BS EN ISO 12127-1:2015ISO 12127-1:2015(E)4 Apparatus4.1 Heating cylinderThe heating cylinder shall be constructed from a suitable

43、metal which can withstand temperatures of over 500C (e.g. Silver Alloy, 925 Sterling Silver). Figures 1, 2 and 3 show an example of the stamp and heating cylinder. The contact surface shall have a diameter of (25,2 0,05) mm and shall be polished. There shall be a central boring which ends 2 mm above

44、 the lower surface of the heating cylinder. This boring is intended to hold the temperature sensor, which is necessary for regulation of the temperature of the heating cylinder, and its diameter should be chosen accordingly. The heating cylinder shall be enclosed by heat-resistant insulation, leavin

45、g free the bottom contact surface.The heating cylinder shall be capable of being heated to over 500C and be capable of maintaining the chosen testing temperature.4.2 CalorimeterThe calorimeter (as shown in Figure 4) consists of a cylindrical disc of black anodized pure aluminium of (25 0,05) mm diam

46、eter, and thickness of approximately 5.0 mm and a mass of (6,63 0,03) g, which is pushed into a mounting made from polyamide 6.6 so as to be a tight fit. The upper contact surface of the disc shall be surface ground before anodization and shall have a thermocouple attached to its lower surface by me

47、ans of adhesive tape.NOTE A PR 6462 BK/02 Thermocoax thermocouple or equivalent has been found to be suitable.1)4.3 AssemblyFigure 5 shows an example of the assembly. The heating cylinder and calorimeter are mounted with parallel faces and with their symmetrical axes in line in a supporting frame. P

48、rovision shall be made for moving at a controlled speed (5,0 0,5 mm/s) either the heating cylinder down towards the calorimeter or the calorimeter up towards the heating cylinder. An additional weight shall be dimensioned in such a way that the contact force is (49 0,5) N. Between measurement, durin

49、g cooling periods, a suitable shielding shall be put between the heating cylinder and the calorimeter in order to prevent the calorimeter from being heated by thermal radiation from the heating cylinder.4.4 Electronic devicesSuitable electronic devices shall be provided to raise the temperature of the heating cylinder to the chosen testing temperature and maintain this temperature to 2C. control the rate of contact; measure and register the calorimeter temperature to an accuracy of 0,1C; measure the threshold time.5 Samplin
