“We have been working with you since more than 10 years. During this period your quality & delivery performance found is very good. Even when we arranged a supplier meet in 2012 we awarded you as a best supplier of the year in Bought out item category. Whenever we had any new developments your support was perfect. Overall your performance was very good & we hope the same in future too, We wish you all the best for your business growth.”

“We are working with Harkesh Rubber since 3 years. Our initial development of few seals for one of the important project developed and supplied by them as per the schedule. We found the quality and commitment for overall business is good. The response and technical support for our need is fair and on-time. Overall the services and co-operation found to be satisfactory. We wish the young and energetic Harkesh Rubber team a very best in all the future endeavours.”

“Harkesh Rubber Industries has been our co-partner for the supply of the rubber and its allied products from past 2 years which we used in our daily final product made for Indian Railways. We find the quality of product supplied by them in superior quality which lowest lead time. Overall the services and cooperation found out to be satisfactory in all key areas.”

“In all honesty I have to say that for us it's really a pleasure to do business with you now already more than 5 years. In the whole time you had never let us down, your delivery performance is nearly perfect, the service which we get is quicker than quick. The product quality has been never a problem and when we had an issue you help us always to solve it. This reliability is where we trust in and what makes our decision to work with you also in the future very easy.”

“Dear Harkesh Rubber Team, We have been working with you since last 6 years. During this period your Quality, Delivery and Performance found very good and consistent. During the development of new products specially FKM/FPM gaskets, we had very good technical support by your team, and we hope in future it will remain same. We wish you all the best for your business growth. Thanking you,”

Understanding ASTM D2000 Specifications

1. Standards

2. Year Last Revised

3. Units of Measure

4. Grade

5. Type and Class

6. Hardness

7. Tensile Strength

8. Additional Requirement Suffixes

To gain a better understanding of ASTM D2000 specifications, let us take the following example:

ASTM D2000 03 M2 BG 717 B14 EO14 EO34 F17

When it comes to potable drinking water (DW), the most important thing is to keep the water clean, safe, and pollutant-free. For the DW industry, our elastomer products comply with the following standards:

1) Standards

When it comes to specifying elastomer products, the standard will be ASTM D2000.

2) Year Last Revised

It is a two-digit code that specifies the year in which the standard was last revised. The value is 03 in our example.

3) Units of Measure

It is the units of measure that are used to report the results of the test. This will be denoted by including the letter M, which is included in our example.

4) Grade

The grade highlights the level of test requirements needed for the elastomer. A grade of value 1 specifies that only basic requirements are needed. Grades of 2-9 indicate necessary additional test requirements. The value is 2 in our example.

5) Type and Class

ThASTM D2000 classifies rubber materials types based on temperature resistance. The specification also indicates that the elastomers must meet specific requirements post 70 hours, and 100DC of heat aging at different temperatures.

Change in Hardness: ±15 points
Change in Tensile Strength: ±30%
Change in Elongation: -50%

Class is generally used to differentiate elastomer materials, based on their resistance when immersed in IRM 903 Oil for 70 hours.

Listed below are the type/class assigned to some common materials:

In the case of our example, the type/class is BG.

6) Hardness

The hardness of the elastomer is indicated by the durometer range specified in Shore A units, followed by ± 5 durometer. To get the actual value of the elastomer, the call-out value is multiplied by 10.

In the case of our example, the hardness is indicated by – 70 ± 5 durometer.

7) Tensile Strength

Tensile strength is measured in psi for English units and MPa for metric units. The minimum tensile strength is 17 MPa in our example.

8) Additional Requirement Suffixes

The rest of the ASTM D2000 specification is suffix requirements. They are preferred when the basic requirement for a specific type and class of a rubber material is not enough to achieve the required properties in the finished product.

As shown in the following table, the first letter of the suffix indicates the required test.

Suffix Required Test
A Heat Resistance
B Compression Set
C Ozone or Weather Resistance
D Compression-Deflection Resistance
EA Water Resistance
EF Fuel Resistance
EO Oil and Lubricant Resistance
F Low-Temperature Resistance
G Tear Resistance
H Flex Resistance
J Abrasion Resistance
K Adhesion
M Flammability Resistance
N Impact Resistance
P Staining Resistance
R Resilience

Note that for each suffix, the first letter(s) are always followed by numbers. The first number indicates the test method that needs to be used and the test duration. The second number specifies the testing temperature.

In the case of our example, the letter ‘B’ of the first suffix specifies the requirement of compression set, and the ‘14’ specifies the test methods.
