HG/T 3526-2011工業(yè)循環(huán)冷卻水中硝酸鹽的測(cè)定.磺基水楊酸分光光度法

重要提示：本標(biāo)準(zhǔn)使用的強(qiáng)酸;強(qiáng)堿具有腐蝕性，使用時(shí)應(yīng)注意。濺到身上時(shí)，用大量水沖洗。本標(biāo)準(zhǔn)規(guī)定了采用磺基水楊酸分光光度法測(cè)定工業(yè)循環(huán)冷卻水中硝酸鹽的方法。本標(biāo)準(zhǔn)適用于工業(yè)循環(huán)冷卻水中硝酸鹽含量為0.1 mg/L～10.0 mg/L水樣的測(cè)定。

HG/T 3657-2017水處理劑 異噻唑啉酮衍生物

本標(biāo)準(zhǔn)規(guī)定了水處理劑異噻唑啉酮衍生物的要求、試驗(yàn)方法、檢驗(yàn)規(guī)則以及標(biāo)志、包裝、運(yùn)輸、貯存。本標(biāo)準(zhǔn)適用于水處理劑異噻唑啉酮衍生物，該產(chǎn)品主要用作工業(yè)水處理中的殺生劑，還可應(yīng)用于涂料、造紙、油田、農(nóng)業(yè)等領(lǐng)域。

DIN EN 12828-2014建筑物中的供暖系統(tǒng).水基供暖系統(tǒng)的設(shè)計(jì)

This European Standard specifies design criteria for water based heating systems in buildings with a maximum operating temperature of up to 105 °C. In case of heating systems with maximum operating temperatures over 105 °C other safety aspects than those described in 4.6 may apply. The other clauses of this European Standard are still valid for those systems.This European Standard does not amend product standards or product installation requirements. This standard covers the design of:? heat supply systems;? heat distribution systems;? heat emission systems;? control systems.This European Standard takes into account heating requirements of attached systems (e. g. domestic hot water, process heat, air conditioning, ventilation) in the design of a heat supply, but does not cover the design of these systems.This European Standard does not cover requirements for installation or commissioning or instructions for operation, maintenance and use of water based heating systems.This European Standard does not cover the design of fuel and energy supply systems.
