Both modulated differential scanning calorimetry (MDSC) and dynamic differential scanning calorimetry (DDSC) are registered tradenames for instrumental techniques which are part of the temperature-modulated differential scanning calorimetry (TMDSC) family. Both oscillate their input ramps differently in that the MDSC uses a sine wave while DDSC generates a sawtooth wave. Although we have found similarities between both techniques we do note some differences. These differences primarily occur in the melting reversing signal for the same conditions and as one changes period and amplitude. These differences may be ascribed to the different time response as noted between a heat flux and power compensation DSC.

Limited License. ASTM grants you a limited, non-transferable license as follows: The right to download an electronic file of this ASTM Document for temporary storage on one computer for purposes of viewing, and/or printing one copy of the ASTM document for individual use. Neither the electronic file nor the single hard copy print may be reproduced in any way. In addition, the electronic file may not be distributed elsewhere over computer networks or otherwise.

The single hard copy print may only be distributed to other employees for their internal use within your organization; it may not be copied. This ASTM Document may not otherwise be sold or resold, rented, leased, lent or sub-licensed. The Subscriber will be responsible for all access control and security measures necessary to ensure that the Subscriber's IP addresses are not used to access the journals other than by authorized Users.
ASTM International grants to the Subscriber and Authorized Users at the Subscriber's Authorized Site, online access to ASTM's journal for which the Subscriber maintains a current subscription to the print or online version. This grant extends only to the Subscriber and such Authorized Users individually and may not be transferred to, or extended to, others. For reprints of a journal article, please contact ASTM Customer Service, 100 Barr Harbor Dr., PO Box C700, West Conshohocken, PA 19428, phone: 610-832-9555; fax: 610-832-9585; e-mail: email@example.com
Verification: ASTM has the right to verify compliance with this License Agreement, at its expense, and at any time during the course of normal business hours. To do so, ASTM will engage an independent consultant, subject to a confidentiality agreement, to review your use of ASTM Documents. You agree to permit access to your information and computer systems for this purpose. Verification will take place upon no less than 15 days notice, during normal business hours and in a manner that does not interfere unreasonably with your operations. If verification reveals unlicensed use of ASTM Documents, you must reimburse ASTM for the costs incurred in verification and reimburse ASTM for any unlicensed uses. By invoking this procedure, ASTM does not waive any of its rights to enforce this Agreement or to protect its intellectual property by any other means permitted by law.
Passwords. You must immediately notify ASTM of any known or suspected unauthorized use(s) of your password, or any known or suspected breach of security, including the loss, theft or unauthorized disclosure of your password or any unauthorized access to or use of The ASTM Document. You are solely responsible for maintaining the confidentiality of your password and for ensuring the authorized access and use of The ASTM Document.
Definitions. For purposes of this License, an Authorized Site is a localized site (one geographical location) that is under a single administration at a single location. For a Subscriber with locations in more than one city, each city is considered to be a different site. For a Subscriber with multiple locations in the same city, each location is considered to be a different site. (If you are seeking online access for multiple sites, please contact Kathe Hooper, ASTM International, at firstname.lastname@example.org or phone: 610-832-9634). Authorized User means only the employees, faculty, staff, and students officially affiliated with the Subscriber at the Authorized Site, and persons with legal access to the library's collections and facilities at the Authorized Site, using an IP address within the range identified in the subscription. Authorized Users may be persons remote from the Subscriber's physical location whose access is administered from the Authorized Site, but not persons at remote sites or campuses with separate administrations. For example, an employee of the Subscriber may be considered to be an Authorized User when accessing the Subscriber's network from home or while traveling to another city; however, employees of a branch campus or facility in another city are not considered to be Authorized Users. Subscriber is the person or entity which has subscribed to the ASTM journal and agreed to the terms of this limited license.
