3 Terms and definitions For the purpose of this Part of EN 1677 the following definitions apply.
3.1
working load limit (WLL) Maximum mass that a component is authorized to sustain in general lifting service, expressed as a code.
NOTE This term has the same meaning as the term maximum working load used in annex A of
EN 292-2: 1991/A1: 1995. 3.2
manufacturing proof force (MPF) Force applied to the component during the manufacturing proof test.
3.3
breaking force (BF) Maximum force reached during the static tensile test of the component, at which the component fails to retain the load.
3.4
traceability code Series of letters and/or numbers marked on a component that enables its manufacturing history, including the identity of the cast of steel used, to be traced.
SIST EN 1677-1:2001+A1:2009
EN 1677-1:2000+A1:2008 (E) 6 3.5
competent person Designated person, suitably trained, qualified by knowledge and practical experience, and with the necessary instruction to enable the required test and examination to be carried out.
NOTE Clause 4.18 of EN ISO 9002:1994 gives guidance on training. 3.6
lot Specified number of components from which samples are selected for testing purposes, and that have been manufactured from the same cast of steel and subjected to the same heat treatment process.
4 Hazards Accidental release of a load, or release of a load due to failure of a component puts at risk, either directly or indirectly, the safety or health of those persons within the danger zone.
In order to provide the necessary strength and durability of components this Part of EN 1677 gives requirements for the design, manufacture and testing to ensure the specified levels of performance are met.
Since failure can be caused by the incorrect choice of grade and specification of component, this Part of EN 1677 also gives requirements for marking and the manufacturer’s certificate.
Risk of injury due to sharp edges, sharp angles or rough surfaces when handling is also covered by this Part of EN 1677.
Those aspects of safe use associated with good practice are given in EN 818-6:2000.
Table 1 contains those hazards which require action to reduce risk identified by risk assessment as being specific and significant for forged steel components, Grade 8.

EN 1677-1:2000+A1:2008 (E) 7 5 Safety requirements 5.1 General 5.1.1 Articulation The dimensions of the forged steel components covered by this Part of EN 1677 shall be such as to ensure articulation so that the force imposed is transmitted in the intended direction. 5.1.2 Relative movement Parts of mechanical joining devices, such as pins and their securing elements, shall be so designed and manufactured that, after assembly, no unintended displacement can occur. NOTE The effects of wear, corrosion of securing elements or rough usage should be considered. 5.2 Materials and heat treatment 5.2.1 Quality of material 5.2.1.1 General Within the limitations given in 5.2.1.2 to 5.2.1.4 the manufacturer shall select the type of steel, to be used so that the finished component, when suitably heat-treated conforms to the mechanical properties specified in this Part of EN 1677. 5.2.1.2 Type of steel The steel shall be produced by an electric process or by an oxygen blown process. 5.2.1.3 Deoxidation The steel shall be fully killed as defined in EN 10025: 1993, be stabilized against strain age embrittlement, and have an austenitic grain size of 5 or finer when tested in accordance with ISO 643. This shall be accomplished by ensuring that the steel contains sufficient aluminium (minimum 0,025 %) to permit the manufacture of components stabilized against strain age embrittlement during service. 5.2.1.4 Chemical composition The steel shall contain alloying elements in sufficient quantities so that the finished component, when heat treated in accordance with 5.2.2, not only conforms to the mechanical properties specified in this Part of
EN 1677, but also possesses adequate low temperature ductility in order to work satisfactorily in the temperature range -40 °C to 400 °C. The steel shall contain at least two of the three alloying elements, in the minimum percentages shown in
table 2. Table 2 — Chemical composition - Alloying elements Element Minimum mass content as determined by cast analysis %

Maximum mass content as determined by Element Cast analysis % Check analysis % Sulfur 0,025 0,030 Phosphorus 0,025 0,030
5.2.2 Heat treatment Each component shall be hardened from a temperature above the AC3 point and tempered before being subjected to the manufacturing proof force. The tempering temperature shall be a minimum of 400 °C.
The tempering conditions shall be at least as effective as a temperature of 400 °C maintained for a period of
1 h.
NOTE A method of verification is as follows. After the components have been reheated to and maintained for 1 h at 400 °C and then cooled to room temperature; they should conform in the finished condition to columns 3 and 4 of table 4. Surface hardening shall not be permitted for load bearing parts of the component.
5.3 Manufacturing methods and workmanship 5.3.1 Manufacture Each forged part of a component shall be forged hot in one piece. Excess metal from the forging operation shall be removed cleanly leaving the surface free from sharp edges. After heat-treatment, furnace scale shall be removed.
Edges of machined surfaces shall be rounded to eliminate cutting edges and to ensure attainment of mechanical properties of the component.
Welding shall not be used during the manufacture of components unless:
a) none of the parts to be welded are load bearing; or b) the area affected by the weld is not to be subjected to load under normal operating conditions or under any foreseeable misuse of the component, and the welding is completed before heat treatment. NOTE Care should be taken during welding to ensure that the mechanical properties of any load bearing parts of the finished component are not affected. All welds shall be smoothly finished. 5.3.2 Surface finish The ‘f
