4 通用技術要求
采用的制造方法,應能保證產品有完整的表面和棱邊,而沒有毛刺。通常,不要求去除諸如開槽或鍛壓、沖壓或切邊等工藝造成的小毛刺。然而,任何影響產品性能或者觸摸時有安全危險的毛剌,均應去除。标準的螺栓、螺釘、螺柱和螺母應規定下列部分:
a)機械性能(性能等級、材料);
b)產品等級(公差);
c)标準化的幾何特征(如需要時);
d)表面覆蓋層(如要求時);特殊技術要求(如同意時)。
所有數據與制成品有關。除另有專用标準或供需之間的協議,否則不應規定制造過程。
超出螺栓和螺釘支承面的切邊毛刺是不允許的。
除非另有規定,否則允許螺栓和螺釘留有中心孔。
除非已規定了一種表面覆蓋層,產品的表面處理應為:
——不經處理,用于鋼制產品,或
——簡單處理,用于不鏽鋼或有色金屬產品。
如無其他協議,交付的螺栓、螺釘、螺柱和螺母應是清潔的,并塗有防鏽油。
