標(biāo)準(zhǔn)解讀

《GB/T 36917.2-2024 牙科學(xué) 技工室用刃具 第2部分:技工室用硬質(zhì)合金刃具》相較于《GB/T 36917.2-2018 牙科學(xué) 技工室用刃具 第2部分:技工室用硬質(zhì)合金刃具》,在多個方面進(jìn)行了更新和調(diào)整。主要變化包括但不限于以下幾個方面:

  1. 術(shù)語與定義:新版本對某些專業(yè)術(shù)語進(jìn)行了修訂或新增,以更準(zhǔn)確地反映當(dāng)前行業(yè)內(nèi)的通用語言和技術(shù)發(fā)展情況。

  2. 材料要求:對于硬質(zhì)合金材料的性能指標(biāo)提出了更加嚴(yán)格的要求,比如硬度、耐磨性等關(guān)鍵參數(shù)可能有所提高,旨在確保刃具使用壽命更長、加工精度更高。

  3. 尺寸公差:針對不同類型的刃具,其幾何形狀及尺寸公差范圍可能有所調(diào)整,這有助于提升產(chǎn)品的互換性和適用性。

  4. 表面處理:增加了關(guān)于刃具表面涂層或處理方法的新規(guī)定,強調(diào)了改善耐腐蝕性、減少摩擦等方面的重要性。

  5. 測試方法:改進(jìn)和完善了部分檢測項目的試驗條件及操作步驟,使得測試結(jié)果更加可靠且具有可比性。

  6. 包裝運輸:細(xì)化了產(chǎn)品包裝標(biāo)識信息以及運輸過程中的保護(hù)措施建議,力求降低物流環(huán)節(jié)中可能對產(chǎn)品質(zhì)量造成的影響。
