This standard is based on ASTMD113. redrafted 1999. This standard ASTMD113.1999 main technical differences are as follows. --- The standard delete the reference file ASTMC670, ASTME1, ASTME11 three references (see ASTM D113.1999 Chapter 2); --- Because they do not belong to the state content standards, this standard delete meaning and purpose (see ASTMD113.1999 Chapter 3); --- Because sifting process may affect the ductility of the sample, so this standard sieving deleted the relevant content (see ASTMD113.1999 5.1); --- When the temperature of the sample can affect the sample ductility properties of sample time and sample quality-related, so this standard to increase the heating temperature and heating Between the restriction that "oil asphalt heating oil temperature does not exceed the expected softening point of 90 ℃; sample heating temperature coal tar pitch Coal tar pitch is expected to not more than the softening point of 60 ℃. Heating time of the sample does not affect the nature of the sample and the sample to ensure adequate As short as possible on the basis of the flow. "(See the present version 5.2); --- In order to correctly judge the effectiveness and proper report analyzed data sample parallel data, this report adds to the standard three measured values The limits. That is, "if the three measured value within 5% of their average value, averaged measurement results as three parallel measurement results fruit. If the measured value is not less than three times the average of 5%, but two high values \u200b\u200bwithin 5% of the average, the most discarded Low measured value, whichever is the higher value of the two as the average of the measurement results, otherwise re-determination. "(See Chapter 7 of this edition); Repeatability and expressed in 1999 in the form of graphs. --- In order to facilitate the use of precision standard, this standard will ASTMD113 Reproducibility repair translated into concrete figures (see Chapter 8 of this release, ASTMD113.1999 7.1). This standard ASTMD113.1999 reg changes are as follows. --- The 1.1 "asphalt specimen at a certain temperature at a constant speed to stretch the length of the fracture of the specimen shall comply with the provisions in 5.1 size. ECA special instructions, test temperature is 25 ℃ ± 0.5 ℃, tensile speed of 5cm/min ± 0.25cm/min. "Inside Yung moved to Chapter 3 of this standard method summary; --- The standard delete ASTMD113.1999 Chapter 3, meaning and purpose; --- The increase in Chapter 3, Standard Method summary; --- The standard delete ASTMD113.1999 in Chapter 8; --- This standard ASTMD113.1999 Chapter 5 Experimental procedure is divided into two chapters, namely Chapter 5 and Chapter 6 Preparing Real Inspection step; other chapter number changes accordingly. This standard ASTMD113.1999 compared to editorial changes as follows. --- Remove all brackets non-SI units, retained SI units (see text). This standard replaces GB/T 4508-1999 "Determination of asphalt ductility." This standard and GB/T 4508-1999 major content changes are as follows. --- This standard GB/T 4508-1999 range "1.1 asphalt specimen at a certain temperature at a constant speed to stretch at break The length of the specimen shall conform to the dimensions specified in 5.1. ECA special instructions, test temperature is 25 ℃ ± 0.5 ℃, tensile speed 5cm/min ± 0.25cm/min. "Move to Chapter 3 of this standard method summary; --- This standard 1999 Edition Chapter 1, the range of "1.2 This standard applies to the determination of the extension of the asphalt, also suitable for the determination of coal Ductility tar pitch. "To" This standard applies to the determination of ductility of bituminous materials. "; --- Delete this standard GB/T 4508-1999 Chapter 4, meaning and purpose. Corresponding changes for the subsequent chapter number; --- The standard delete GB/T 4508-1999 Chapter 4 instruments and materials, "5.5 to 0.3 ~ 0.5mm mesh metal Net "and make corresponding changes in the subsequent chapter number; --- This standard removed the restrictions sample heating time, the words "heating time of the sample does not affect the nature of the sample and the sample charge guarantee As short as possible on the basis of sub-flows. "(See this edition 5.2); --- The 6.2 sample heating temperature is limited to "tar asphalt heating temperature does not exceed the expected softening point of 60 ℃, petroleum pitch does not exceed It had expected a softening point of 90 ℃. "(See this edition 5.2); --- This standard GB/T 4508-1999 5.4 Notes content to "if the extension of the sample is placed in 25 ℃ standard penetration bath When the constant temperature above the thermometer can be used GB/T 4509 set forth in the thermometer in place "(see this edition 4.4); --- The GB/T 4508-1999 support plate in 5.7 "metal plate or glass" to "brass plate"; --- The GB/T 4508-1999 "on a sample drawn into a cone" to "sample was drawn into a tapered or linear or cylindrical." (See Excerpts 6.3, GB/T 4508-1999 7.3); --- The 1999 edition of the standard delete 5.2 "put the melted sample sieved." 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 was drafted. China University of Petroleum (East China) Heavy Oil Research Institute. The main drafters of this standard. Superficially, car Jinliang.
