標(biāo)準(zhǔn)解讀

《LY/T 2229-2013 木質(zhì)相框》標(biāo)準(zhǔn)由中國(guó)國(guó)家林業(yè)局提出并歸口,旨在規(guī)范木質(zhì)相框的產(chǎn)品質(zhì)量要求、試驗(yàn)方法、檢驗(yàn)規(guī)則以及標(biāo)志、包裝、運(yùn)輸與貯存等方面的內(nèi)容。該標(biāo)準(zhǔn)適用于以木材或人造板為主要材料制成的用于裝飾照片或其他圖片的木質(zhì)相框。

根據(jù)此標(biāo)準(zhǔn),首先明確了術(shù)語(yǔ)和定義部分,包括對(duì)木質(zhì)相框基本結(jié)構(gòu)(如框架、背板等)及其組成部分的具體說(shuō)明。接著,在技術(shù)要求方面,詳細(xì)規(guī)定了外觀(guān)質(zhì)量、尺寸偏差及形位公差、物理力學(xué)性能等多個(gè)方面的具體指標(biāo)值。例如,對(duì)于外觀(guān)而言,要求表面平整光滑無(wú)明顯缺陷;而對(duì)于物理力學(xué)性能,則需滿(mǎn)足一定的抗彎強(qiáng)度、含水率控制范圍等條件。

此外,《LY/T 2229-2013 木質(zhì)相框》還制定了相應(yīng)的測(cè)試方法來(lái)驗(yàn)證產(chǎn)品是否符合上述各項(xiàng)技術(shù)要求,包括但不限于目測(cè)檢查、使用專(zhuān)用工具測(cè)量尺寸精度、進(jìn)行拉力試驗(yàn)等。同時(shí),該標(biāo)準(zhǔn)也指出了如何實(shí)施抽樣檢驗(yàn),并依據(jù)檢驗(yàn)結(jié)果判斷整批產(chǎn)品質(zhì)量狀態(tài)的原則。
