DS 13080-1:1988 强化钢．第1部分：混凝土结构中不预加应力的强化钢．要求．试验

Standarden henvender sig til producenter af armeringsst?l (st?lv?rker og armeringsstationer), producenter af arme-ringsenheder (armeringsstationer), forhandlere, projekteren-de og udf?rende virksomheder. Armeringsst?l i henhold til denne standard skal leveres med garanteret flyde- eller 0,2-sp?nding fastsat af producenten. Armeringsst?let anvendes til slap armering dvs. ikke for-sp?ndt armering til betonkonstruktioner. Armeringsst?let anvendes til fuld indst?bning i betonkonstruktioner i henhold til DS 411. Standarden omfatter armeringsst?l i dimensionerne til og med 35 mm for varmvalsede ribbest?l og for glat st?l til og med 50 mm samt for koldreducerede, koldprofilerede og koldribbede st?l til og med 14 mm. Standarden stiller krav til armeringsst?ls egenskaber og hen-viser til pr?vningsmetoder for verifikation af, at kravene er opfyldt. Vedr?rende svejsning af armeringsst?l henvises til DS xxxx. For h?jstyrkest?l til sp?ndarmeret beton henvises til DS 13 081 samt for maskinsvejste armeringsnet til DS 13 082.

DS/ISO 3651/1:1977 奥氏体不锈钢.耐晶间腐蚀的测定.第1部分:由测定不锈钢在硝酸介质中的质量损失的腐蚀试验(晶间腐蚀试验)

This International Standard specifies a method for the determination of the resistance to intergranular corrosion of austenitic stainless steels in a nitric acid medium by measurement of the loss in mass (Huey test). It also specifies the purposes which may be assigned to the test.

DS/ISO 3755:1977 一般工程用铸钢

This International Standard specifies requirements for four grades of cast steel for general engineering purposes, after heat treatment. The castings manufactured from these grades of cast steel are generally used in the temperature range-10°C to + 300°C.

Cast steels for general engineering purposes

DS/ISO 3763:1977 锻钢.评定非金属夹杂物含量宏观检查.

1 This International Standard describes the macroscopic methods used in current practice for assessing the content of non-metallic inclusions in wrought Steel products. 2 Macroscopic methods are those dealing with non-metallic inclusions visible to the naked eye or with the aid of a magnifying glass with a magnification of not more than X 10. Only inclusions equal to or greater than 1 mm long are taken into consideration. 3 The methods usually applied and defined in this International Standard are : - the blue fracture test method; - the step machined test method; - the magnetic particle inspection method.
