Foreword

This standard and ISO 721.1991 "Overall solder" (in English) of non-equivalent. This standard and ISO 721.1991 The main differences are as follows. --- Increasing the overall solder "Specifications Code"; --- Increasing the "order content" related provisions; --- Increasing the overall solder the "Components and classification code" content; --- Increasing the size, shape and tolerances; --- Overall brazing head geometry parameters except a shape, the increase in a three-blade, cross, the ball-shaped teeth with composite and other four series; --- Overall brazing head diameter expanded to 51mm; --- Overall specifications caudal peduncle borer, an increase of R25-H25, R28-H25, R28-H28, R32-H28 and other waveform thread caudal peduncle; --- Increasing the overall solder "technical requirements" of the relevant provisions. The standard proposed by China Iron and Steel Association. This standard is under the jurisdiction of the National Steel Standardization Technical Committee. Drafting of this standard. Guizhou three accounted Group Co., Ltd., Metallurgical Industry Information Standards Institute, Steel Research Institute. The main drafters.
