Thermal shock resistance testing identifies the thermal failure areas of products. When a matter is exposed to heat and cold, it expands and contracts. Like other thermal qualities, the rates at which they experience this expansion or contraction differ amongst different materials.
Thermal shock is a sort of structural trauma that can occur to objects as a result of extreme temperature changes. It happens when the tensile strength of the surface material is overcome by strain brought on by the object’s surface expanding or contracting at a different pace than its internal components. The integrity of the product could be compromised by releasing that stress.
The thermal shock resistance test is performed by placing the test article in a unit designed to induce thermal shock by subjecting sample materials to rapidly changing temperatures for a predetermined number of cycles. The unit has a moving basket that allows test subjects to be quickly moved between its two chambers, one hot and one cold. The equipment can generate temperatures ranging from -60°C to 170°C, subjecting the sample to as harsh conditions as the client requires their product to withstand.
Individual product needs will dictate the temperature range and number of cycles applied to the sample, unless the client requests that the test is performed to an existing standard.

ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 test is a standard test method for the analysis of sulfochromate etch solutions used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
