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 to use. Standards can be obtained from appropriate standards authorities. Already Subscribed to this document.
Further application areas include determining the effect of light on the shelf life of foods or technical oils, fats ast lubricants. Numerous upgrade possibilities allow adaption of this cost-effective calorimeter system to sophisticated applications. As the voice of the U. The reference compartment contains an empty aluminum pan and cover equivalent to those used to encapsulate a test sample.
Due to its versatility and the high significance of its analytical output, differential scanning calorimetry DSC is the asrm often employed method for thermal analysis. Play Differential Atsm Calorimeter Video. Your Alert Profile lists the documents that will be monitored.
The DSC Polyma is a completely new concept. The DSC head area contains equivalent sample and reference compartments located adjacent to each other.
Using a DSC differential scanning calorimeter the following are commonly determined: Subscription pricing is determined by: It is also astk to characterize materials for their thermal performance.

A sample weight of 10 to 15 mg is required. Note 1-True heats of fusion can only be determined in conjunction with structure investigation and frequently specialized crystallization techniques are needed.
The sample is heated at a controlled rate and a plot of heat flow versus temperature is produced. Proceed to Checkout Continue Shopping. Of course, our Differential Scanning Calorimeters DSC meet the respective instrument and application standards, including: We have no amendments or corrections for this standard.

The resulting thermal scan is then analyzed. Sensors with high calorimetric sensitivity, short time constants and a condensation-free sample chamber in the calorimeter cell guarantee high detection sensitivity and stable, reproducible baselines over the entire life cycle of a calorimeter: Note 4- To date, there is no similar or equivalent approved ISO standard.
Eutectic purity Specific heat c p Compatibility between components Influence of aging Distribution of the molecular weight peak form for polymers Impact of additives, softeners or admixtures of re-granulates for polymer materials What is the Wstm Between DSC and DTA? The DSC Sirius combines compactness, robustness and ease-of-use with high detection sensitivity, thus offering optimal conditions for quality assurance and failure analysis in areas such as foods, cosmetics, polymers, technical textiles, and organic and inorganic materials.
This standard is also available to be included in Standards Subscriptions. It unites excellent performance and highest flexibility. Compact solids granulates, components, molds, etc. The sample compartment is where an encapsulated sample of about 10 to 15 milligrams is placed for testing. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Note 2-This test method may not be applicable to all types of polymers as written see 6.
