The document specifies requirements for the magnetic particle inspection of ferromagnetic forgings.
Specifies the method and acceptance criteria to be used for the magnetic particle inspection of forgings manufactured from ferromagnetic materials.
本標準規定了鋼鍛件超聲檢測的協議條款、操作規程的編制、人員資格、設備和附件、校準和檢查、檢測時機、表面狀態、靈敏度、掃查、分類、記錄水平和驗收標準。 本標準適用于鐵素體-馬氏體鋼鍛件、奧氏體和奧氏體-鐵素體不銹鋼鍛件超聲脈沖反射式手工檢測方法。供需雙方協商后也可使用液浸法檢測的機械化掃查方法。其他組織的鍛件也可參照使用。 本標準按形狀和生產方法將鍛件分為4類。1、2、3類為簡單外形的鍛件，4類為復雜形狀的鍛件。 本標準不適用于：致密的模鍛件、汽輪機轉子和發動機鍛件。
BS EN 10228-4-2016 鋼鍛件的無損檢驗 奧氏體和奧氏體-鐵素體不銹鋼鍛件的超聲檢驗
This practice shall be used when ultrasonic inspection is required by the order or specification for inspection purposes where the acceptance of the forging is based on limitations of the number, amplitude, or location of discontinuities, or a combination thereof, which give rise to ultrasonic indications. The ultrasonic quality level shall be clearly stated as order requirements.
