Foreword

This revised standard adopts ASTMD312-00 (2006 confirmation) "Housing construction bitumen product specification" (in English). This standard (2006 confirmed) redrafted according ASTMD312-00. This standard ASTMD312-00 (2006 confirmed) changes reg structure. the ASTMD312-00 in Chapter 5 of Sampling into Chapter 6 of this standard, the Chapter 5 Test methods shown in Table 1. The standard Chapter 4; deleted ASTMD312-00 Chapter 9, according to other chapters numbered sequentially deleted after adjustment. This standard ASTMD312-00 (2006 confirmed) The main technical differences are as follows. --- Delete this standard ASTM D312-00 (2006 confirmed) Chapter 2. Referenced Documents 2.1 ASTM D1079 and the ASTMD3461 two references, and increase the SH0164 in Chapter 2, normative references documents; --- ASTMD312-00 softening point divide the product type. Because of asphalt are used penetration grading system, so This standard penetration range into Grades (see Chapter 4 of this edition, ASTMD312-00 4.2); --- Suitable for our country, the present standard 46 ℃ penetration index using the reported values \u200b\u200b(see Chapter 4 of this edition, ASTMD312-00 in 4.2); --- In order to adapt to the current situation of China's construction of petroleum asphalt products, this standard No. 10 Building bitumen 0 ℃ penetration index words "is not small In 3 ", 30 and 40, Building bitumen 0 ℃ penetration index changed to" not less than 6 "(see Chapter 4 of this edition, ASTMD 312-00 4.2); --- The standard according to GB/T 1.1-2000 requirements, delete keyword chapter (Chapter 9 ASTMD312-00 in). Editorial changes to the contents of this standard ASTMD312-00 (2006 confirmed) were as follows. The standard delete ASTMD 312-00-Africa International System of Units, SI reservations. This standard replaces GB/T 494-1998 "Building bitumen." This standard and GB/T 494-1998 main differences are as follows. --- This standard removed brittle point indicators and related content (GB /Chapter 2 and Chapter 4 494-1998 T); --- The standard adds the 10th Building bitumen 0 ℃ penetration index of "not less than 3", 30 and 40, Building bitumen Technical requirements 0 ℃ penetration index of "not less than 6" (see Chapter 4 of this edition); --- This standard solubility index requirement to not less than 99.0% (see Chapter 4 of this edition, GB/T 494-1998 in Chapter 4); --- This standard flash point Technical indicators to not less than 260 ℃ (see Chapter 4 of this edition, GB Chapter 4 494-1998/T). This standard by the National Standardization Technical Committee on Petroleum Products and Lubricants made. This standard by the National Standardization Technical Committee lubricant oil asphalt petroleum products and the Technical Committee. This standard by the Institute of Heavy Oil, China University of Petroleum (East China) responsible for drafting. The main drafters of this standard. Superficially. This standard replaces the standards previously issued as follows. --- GB/T 494-1965, GB/T 494-1975, GB/T 494-1985, GB/T 494-1998. Building bitumen
