But I sincerely hope that you can support the authentic standard. This document shared by this website is only for learning, not for business activities. Published by ASTM International and designed for automotive applications, this classification system is used by many other industries because it’s clear, concise, and highly descriptive.

Many times, customers will ask engineers which specification should be used for a specific rubber compound. Measuring adhesiveness with ASTM D4Method C –. This system is designed to aid in the selection of practical rubber products for specific environments and provides a "line call-out" designation for the specification of elastomer seal materials.

BEOEOFis the second half of the original sample ASTM line call-out. When reading the line call-out the suffix letter denotes the test metho The first suffix “number”, in our grouping, specifies the test method and duration of the test. Tableexcept that a maximum temperature of 150°C (the upper limit of oil stability) shall be used.

Limits of swelling for each class are shown in Table 2. Oils have been replaced by IRM 9and 9Oils, respectively, under Practice D. Each requirement is com-prised of a su˚x letter, calling out the property being teste and the su˚x numbers, which call out the the test method and test temperature. Grade Number The Grade Number designates instances where more extensive tests are required.

In stock and ready to ship. Tables Aand Alist the SAE J2designation (Type and Class) and the type of polymer most often used in meeting the material requirements.

ASTM International è un organismo di normazione statunitense, acronimo di American Society for Testing and Materials International. For Annual Book of ASTM Standards volume information, refer to the standard’s Document Summary page on the ASTM website.

A Summary of Changes section appears at the end of this standard. This classification system covers the properties of vulcanized rubber materials (natural rubber, reclaimed rubber, synthetic rubbers, alone or in combination) that are intended for, but not limited to, use in rubber products for automotive applications. They call out specific Test Methods and Practices. View all product details Most.

We have a specification that applies to the line call out. We have some basic requirements information and then we have what’s known as the suffix requirements portion of the line call out. In our line call-out example, the A in the Asuffix means that a heat resistance test is require where indicates that the test method is ASTM D96 and indicates that the test temperature range is from -25.

Change in tensile strength: ±30% Change in hardness: -50% max. ASTM 美国材料实验协会(American Society of Testing Materials )前身是国际材料试验协会（International Association for Testing Materials, IATM）。19世纪80年代，为解决采购商与供货商在购销工业材料过程中产生的意见和分歧，有人提出建立技术委员会制度，由技术委员会组织各方面的代表参加技术座谈会，讨论解决有关.

Scope: Durometer Hardness is used to determine the relative hardness of soft materials, usually plastic or rubber. The test measures the penetration of a specified indentor into the material under specified conditions of force and time. When the Seal Matters…Gallagher Delivers. Search for: Categories.

This classification system tabulates the properties of vulcanized rubber materials (natural rubber, reclaimed rubber, synthetic rubbers, alone or in combination) that are intended for, but not limited to, use in rubber products for automotive applications. These materials are based on polymers that are all basically TFE and PVME copolymers with CSM presence to allow vulcanization. Su x Requirement tests.

These indicate the additional testing requirements needed to satisfy this speci cation callout.

Designed for automotive applications, this classification system is also used by other industries because it’s clear, concise, and highly descriptive. M = Requirements are in SI units “metric”, if there is no “M” indicate units are in English.

Fulfillment operation is ISO certified. Rubber Sheet, solid. In our example, the material specified would possess a hardness of 70:durometer.
