35、ng contact heat produced by dropping small cylindersDIN EN ISO 12127-1:2016-05 EN ISO 12127-1:2015 (E)4 IntroductionProtective clothing designed to protect against heat and flame can be exposed to direct contact with hot substances or hot surfaces.The diversity of such contact conditions makes it di

36、fficult to evaluate the hazards that can arise from high 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 o

37、f standards concerned with clothing designed to protect against heat and fire.DIN EN ISO 12127-1:2016-05 EN ISO 12127-1:2015 (E)5 1 ScopeThis part of ISO 12127 specifies a test method for the determination of contact heat transmission. It is applicable to protective clothing (including hand protecto

38、rs) and its constituent materials intended to protect against high contact temperatures.Application of this part of ISO 12127 is restricted 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 f

41、ment when the temperature of the calorimeter is 10C above its starting value3 PrincipleThe heating cylinder is heated to and maintained at the contact temperature and a test specimen is placed on the calorimeter. The heating cylinder is lowered onto the test specimen supported by the calorimeter or,

42、 alternatively, the calorimeter with the specimen is lifted up to the heating cylinder. In either case, the operation is carried out at a constant speed. The threshold time is determined by monitoring the temperature of the calorimeter.DIN EN ISO 12127-1:2016-05 EN ISO 12127-1:2015 (E)6 4 Apparatus4

43、.1 Heating cylinderThe heating cylinder shall be constructed from a suitable 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

44、 and shall be polished. There shall be a central boring which ends 2 mm above 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

45、. The heating cylinder shall be enclosed by heat-resistant insulation, leaving 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) consist

46、s of a cylindrical disc of black anodized pure aluminium of (25 0,05) mm diameter, 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

47、anodization and shall have a thermocouple attached to its lower surface by means 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 pa

48、rallel faces and with their symmetrical axes in line in a supporting frame. Provision 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 me
