Confirmation of the calibration of these aetm sensors shall be done at regular intervals. Link to Active This link will always route to the current Active version of the standard.
Measure the volume and record it as residue. Factors Causing Superheating Table 6 gives a summary of the relative bias observed for the samples used in the study. Have the bottom of the flask resting firmly in the hole of the heat satm.
This test method also provides an empirical value of residue, solvent recovery capacity, and loss or non-recovery on heating. Summary of Test Method 4. Both bore corrections and either ice or steam standardization corrections are recommended.
ASTM D – 05 Standard Test Method for Distillation Range of Volatile Organic Liquids
This standard has been approved d178 use by agencies of the Department of Defense. Current edition approved June 10, NOTE 2—Toluene is shown in reference manuals as boiling at Historical Version s – view previous versions of standard. Preparation of Apparatus 8.
If yields are not obtained within these limits, repeat the test. Specific 3 D factors conducive to superheating are as follows, and should be avoided: Therefore, this test method provides a test procedure for assessing compliance with a specification.
HDA 620: Distillation Analyzer
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Record the readings of the distillation thermometer after collecting 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, and 95 mL of distillate. Center the thermometer into the neck of the flask through a tight-fitting cork stopper so that the upper end of the contraction chamber or bulb if Thermometer 2C or IP thermometer 62C is used is level with the lower side of the vapor tube at its junction with the neck of the flask.
It was found that d10778 precision is dependent on the boiling point temperature. Therefore, this test method provides a test procedure for assessing compliance with a specification.
This test method provides a method of measurement of distillation range of volatile organic liquids. S1078 are a non-profit group that run this website to share documents. If a dry point is not obtained that is, if active decomposition should occur before the dry point is reached, as evidenced by a rapid evolution of vapor or heavy fumes; or if there is liquid remaining on the bottom of the flask when the maximum temperature is observed on the distillation thermometerrecord this fact.
Please help us to share our service with your friends. Other means can be employed, such as the use of a platinum-resistance ashm or a National Bureau of Standards thermometer.
Significance and Use 5. Organic liquids are used as solvents in many chemical processes. We need your help to maintenance this website. These should be used only after they have been proven to give results comparable to those obtained when using gas heat.
A small but statistically significant bias was indicated for the automatic and manual D dry point DP. Compound 6 Asm sole source of supply of the Lo-Cap heater known to the committee at this time is Precision Scientific Co. Users should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law. The hole must be perfectly circular, with no irregularities.
Specific hazard statements are given in Section 7. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior wstm use.
