Statement
of Quality Assurance
Since 1984 Hallam Polymer Engineering Co Ltd has sought qualified assessor
approval for its quality management system. This was achieved in January
1988 through British Coal who assessed and approved our quality system
to BS5750 part 2. This approval was maintained for 2 years until the demise
of British Coal, which made it necessary for us, to look at alternative
accredited bodies for registration.
We were assessed and approved by BSI in February 1992 to BS5750:1987 part 2 and have since this time undergone constant monitoring and 'improvement' of our quality system throughout the changes to the British Standard for the last 11 years.
However, the recent release of the new standard to BS.EN.ISO 9000:2000 has caused us to review our requirements as a company and the benefits afforded by us in maintaining registration to a constantly changing and ever demanding standard.
The main point of consideration is in the level of satisfaction achieved by the current quality system, against the need to use valuable resources in re-structuring over a 2-year transitional period without the assurance that this investment in resources will result in a justifiable return.
As a close knit company of 30 employees, we have strived to reduce rejects to an acceptable level and for the last 3 years have achieved levels of 1.5% average reject parts and 1.7% average reject weight of materials used. As manufacture is all manually cast by our workforce we consider these levels to be a tribute to both our monitoring and training techniques in conjunction with our present level of quality management system.
Therefore, we do not feel the need at this time to commit resources in the direction of registration to BS.EN.ISO 9000:2000 when we are satisfied with the quality management system currently in place at Hallam Polymer Engineering.
Testing
Capabilities
HPE carry out physical testing on all production
materials on a regular basis. We maintain an array of test equipment and
the following Iist shows the range of tests performed.
| Test Parameter | Test Units | Standard |
| Hardness, Durometer | Shore A and Shore D | ASTM D2240 |
| 100% Modulos | Mpa (and PSI) | ASTM D412 |
| 300% Modulos | Mpa (and PSI) | ASTM D412 |
| Ultimate Tensile Strength | Mpa (and PSI) | ASTM D412 |
| Elongation at Break | %age | ASTM D412 |
| Tear Strength Graves | KN/m | ASTM D624 Die C |
| Tear Strength Split | KN/m | ASTM D1938 |
| Compression Set | %age | ASTM D395 Method B |
| Rebound Resilience | %age | ASTM D2632 |
| Abrasion Resistance Tabor | Mg loss | ASTM D1044 Tabor H22 |
| Abrasion Resistance Din | mm3 | DIN 53516 |
| Abrasion Resistance NBS | Index | ASTM D1630 |
| Specific Gravity at 24° |
The above list is not definitive and HPE will carry such tests as are considered necessary for specific applications. HPE regularly prepare dedicated quality plans for compliance to customer specifications. Test records are maintained to provide tractability. Dedicated test rigs are available for accelerated material life testing.
