A separate brochure is available. Note 1Notwithstanding the statements on precision and bias contained in this test method; the precision of this test method is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. These are done without need of reference materials. Work Item s – proposed revisions of this standard. This method may also be used for specimens containing moisture.

Remember me for one month. This ensures consistent results for the conventional and the modified needle probe method in the complete measuring range. More details on the science: TP08 is suitable for use by ISO certified labs. Active view current version of standard.

As hard or brittle sample materials are often difficult to prepare for inserting a conventional x5334-08 probe, our modified method uses a needle embedded in the underside of a disk-shaped probe body which is just placed on top of the sample surface probe for plane surfaces. There were no books found for the applied search filters.

They yield more accurate results, and they can be used to detect disturbances in the data by comparing the measured temperature curve to the theoretical curve form. Downloads Download Product Manual. The probe is inserted in the medium that is investigated. The most common approximation method calculates thermal conductivity fron the slope of a straight line fitted to the measuring data.

ASTM-D, –

Min 20 mm radius. It can be used where standard size probes are too large for the available sample dimensions.

Mini VLQ now available. Enter your account email address to request a password reset: 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.

A high quality measurement with TP08 requires that not only the sample but also the base are at a stable preferably the same temperature. D533-08 sample size is not critical, as long as a 20 mm radius around the needle is covered.

TK04 uses the well-established transient line source method widely known as needle probe method according to ASTM D The method then yields absolute thermal conductivity values without requiring any time-consuming reference or comparison measurements.

Alternative models, for instance smaller, more robust or temperature resistant have been manufactured on request. Copyright Compu-tecture, Inc. Are you sure you want to empty the cart? Because of the relative importance of the thermal equilibrium between base and sample, an optional container can be ordered with TP In TP08 the reference junction of the thermocouple is located in the base.

Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. The new Mini VLQ is a 50 mm long astmm probe with a diameter of 2 mm for small samples.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Highly Accurate Evaluation Adtm The thermal conductivity of the sample is calculated from the temperature rise with time registered by the probe. For permanent installation in soils, a dedicated model, TP01, is available. Significance and Use The thermal conductivity of both undisturbed and remolded soil specimens as well as soft rock specimens d334-08 used to analyze and design systems used, for example, in underground transmission lines, oil and gas pipelines, radioactive waste disposal, and solar thermal storage facilities.
