Six of the classifications relate to materials commonly used in manufacturing enclosures, structural parts and insulators found in consumer electronic products 5VA, 5VB, V-0, V-1, V-2, HB. Thank you very much for your input.
EC-Certificate for Geosynthetics
The remaining three classifications are assigned to very thin films commonly used in flexible printed wiring boards, generally not capable of supporting themselves in a horizontal position VTM-0, VTM-1, VTM Il existe deux modes d’hospitalisation sans consentement ou sous contrainte: View forum Certificaf forum without registering on UserVoice.
Test results may lead to one of the following outcomes:. When an end-product manufacturer orders a Recognized plastic in a custom color, the Recognized plastics supplier must stop production, clean the machinery, and proceed with a special run for the production of this custom-color. Mutual recognition of national accreditation bodies under the ILAC agreement, we ensure worldwide validity of your calibration certificate and test results. If a material has been investigated under the thermal-aging program, the relative temperature index RTIin degrees C, shown is based on a comparison with a material which has acceptable service experience and correlates numerically with the temperatures above in which the material is likely to degrade prematurely.
Test results may lead to one of the following outcomes: Calibrating materials testing machines and instruments Benefit from our many years of experience in calibrating testing systems at Germany’s biggest testing laboratory. This can occur in the presence of open switch contacts or in the event of the failure of an electrical connection.
Patents, Trademarks, Copyright Law: Return to KudoZ list. In the tensile direction: Also, these specimens may not drip any flaming particles. Vote Promote or demote ideas.
Calibrating materials testing machines and instruments
I have made the glossary entry to account for expressions used outside the MHA and put brackets round the word “compulsory”. Polymeric materials in direct contact with or in close proximity to overloaded or arcing electrical parts could ignite.
The Recognition of color concentrates requires submittal and testing for each Recognized vertically rated base resin. Hardness Calibration of hardness testers to Cetrificat, Vickers, Rockwell, Knoop, and ball indentation methods.
Property retention following exposure to long-term elevated temperature air-oven agingwater, ultraviolet light, cold, and other outside influences may also be evaluated. Our flexibility and proximity to our customers are unique and are especially important to us. By dry blending the two materials without exceeding the published maximum let-down ratio, end-product manufacturers can produce the contracted part, which is typically more cost-effective than ordering a custom Recognized plastic.
Recognition of a color concentrate for use with a vertically rated Recognized base resin is specific and requires the submittal of standardized test samples. A measured value is approached 50 times with a working standard master thus achieving an average value and standard deviation, so that together with a set value and a tolerance limit, a capability index of C g and C gk can be calculated. Term search Jobs Translators Clients Forums.
Thermal-aging program Most materials covered by this program have been investigated with respect to retention of certain critical properties including dielectric, tensile and impact as part of a longtime thermal-aging program conducted in accordance with UL B, Polymeric Materials, Long Term Property Evaluations.
Hardness Calibration of loading devices of hardness testing machines. Diane de Cicco France.
Certificate of Analysis | BioBall
Puncture and impact strength Calibration of impact testers. The Lancet uses this term in such cases. At a minimum this must reach a value of 1.
It is a request hft a next of kin, for instance, sees that someone is in such a state mentally for instance that he or she needs care. If a material has not been investigated under the thermal-aging program, the RTI shown is based on the generic class of the material.
The three vertical ratings — V2, V1 and V0 — indicate that the material was tested in a vertical position and self-extinguished within a specified time after the ignition source was removed.
The Recognized concentrate package can be shipped directly to the manufacturer as well. The vertical ratings also indicate whether the test specimen dripped flaming particles that ignited a cotton indicator located below the sample. Mental Health Act, where a third party applies to have someone admitted. Read more Show less. This test relates to the establishment of an electrically conductive path on the surface of a solid, insulated material as a result of electrical stress.
High temperature Calibration of thermo-elements of high-temperature furnaces. ZwickRoell service technicians are located in Germany, Austria, Switzerland, and Denmark, as well as in Benelux countries, enabling us to guarantee fast, flexible, and prompt on-site calibration service.
To that extent I agree with Kirsten in the necessity to make that clear in the translated version: Temperature device Calibration of temperature in center of test-chamber of temperature chambers. Reliable test results—we calibrate more accurately than the standard requires The range for calibration depends on the type of load cell on the materials testing machine, the machine electronics, and the display resolution.
Mechanical strength RTI ormechanical without impact is associated with critical mechanical strength where impact resistance, resilience and flexibility are not essential.
Post Your ideas for ProZ. Three of the remaining six classifications relate to low-density foam materials commonly used in fabricating speaker grills and sound-damping material HF-1, HF-2, HBF.
