Every measurement is performed under the rigorous framework of ISO/IEC 17025, and each report bearing the ILAC mark is unconditionally accepted by regulatory authorities, notified bodies and supply‑chain partners in all major economies. The anti‑static glass fiber board testing service subjects the sheet or the machined component to a comprehensive suite of electrical, physical, mechanical, thermal and chemical‑resistance evaluations, quantifying the critical parameters that govern the reliable dissipation of the electrostatic charge, the prevention of the electrostatic‑discharge damage to the sensitive electronic components, and the structural and the fire‑safety performance of the board in the semiconductor, the aerospace, the pharmaceutical and the defence applications.
Product Samples We Regularly Subject to Anti‑static Glass Fiber Board Testing
The surface‑resistivity meters, the static‑decay analysers, the universal tensile‑and‑flexural test frames, the pendulum impact testers, the thermal‑analysis instruments, the flammability‑test chambers, the environmental‑ageing ovens and the chemical‑immersion baths in our facility accommodate a broad variety of anti‑static glass‑fibre board grades and their converted products. The following categories represent the most frequently tested items:
- Anti‑static epoxy‑glass laminate sheets – the NEMA‑grade FR‑4, the G‑10 and the G‑11 types that are modified with the conductive carbon‑black, the metallic‑fibre or the ionic‑surfactant additives to achieve the static‑dissipative or the conductive electrical properties, used for the printed‑circuit‑board assembly fixtures, the soldering pallets and the ESD‑safe bench‑tops
- Anti‑static polyester‑glass and the vinyl‑ester‑glass boards – the pultruded and the compression‑moulded sheets that are used for the cleanroom wall‑linings, the floor‑panels and the equipment‑housings in the pharmaceutical and the biotechnology industries, evaluated for the chemical‑resistance and the low‑outgassing characteristics
- Anti‑static glass‑fibre‑reinforced phenolic and the melamine‑resin boards – the hard, the abrasion‑resistant and the low‑smoke‑emission grades that are specified for the mass‑transit vehicle interiors, the aerospace cabin panels and the defence‑electronics enclosures, tested for the flame‑spread, the smoke‑density and the toxicity compliance
- Multi‑layer and the surface‑coated anti‑static glass‑fibre composites – the products that incorporate a conductive‑polymer surface‑layer, a metallic‑mesh or a carbon‑nanotube‑reinforced ply to achieve the targeted resistivity range while preserving the mechanical and the dielectric properties of the base laminate
- Prototype, aged and the field‑retrieved anti‑static glass‑fibre board specimens – the samples that have undergone the thermal‑cycling, the elevated‑humidity exposure, the repeated‑cleaning or the long‑term service, submitted for the residual‑resistivity, the mechanical‑property and the surface‑degradation assessment
Electrical Resistivity and Static‑Dissipative Performance – Anti‑static Glass Fiber Board Testing According to ASTM D257, IEC 61340‑2‑3 and ANSI/ESD S20.20
- Determination of the surface resistivity and the resistance‑to‑ground by the concentric‑ring electrode method according to ASTM D257 (Standard Test Methods for DC Resistance or Conductance of Insulating Materials) and IEC 61340‑2‑3 (Electrostatics – Methods of test for determining the resistance and resistivity of solid materials used to avoid electrostatic charge accumulation): the board specimen is placed in a guarded‑electrode test fixture, and a defined direct‑current voltage – typically 100 V or 500 V – is applied between the inner and the outer ring‑electrodes. The surface resistivity in the ohms per square and the volume resistivity in the ohm‑metres are calculated from the measured current and the electrode geometry. The results are reported after the specified electrification time, and the board is classified as “conductive” (surface resistivity below 10⁴ Ω), “static‑dissipative” (10⁴ Ω to 10¹¹ Ω) or “insulative” (above 10¹¹ Ω) according to the ANSI/ESD S20.20 and the IEC 61340‑5‑1 standards. This anti‑static glass fiber board testing service is the primary classification test for every ESD‑safe worksurface and enclosure material.
- Measurement of the resistance‑to‑groundable‑point and the system‑level resistivity according to the ANSI/ESD STM4.1 (Worksurfaces – Resistance Measurements) and the IEC 61340‑2‑3: a conductive electrode is placed on the board surface, and the resistance between the electrode and the groundable‑point – such as the conductive‑foil backing or the grounding‑stud – is measured, providing the direct, application‑relevant data that the facility‑engineer uses to verify the correct grounding of the installed ESD‑protective worksurface.
- Static‑decay and the charge‑dissipation time measurement by the charged‑plate method according to IEC 61340‑2‑1 (Electrostatics – Measurement methods – Ability of materials and products to dissipate static electric charge) and the US Federal Test Standard 101C Method 4046: the board specimen is mounted on a grounded metal plate, and a high‑voltage corona source charges the surface to a defined initial potential, typically 5 000 V. The time required for the surface potential to decay to 1 % or 10 % of its initial value is recorded in seconds, and the result must be below the limit – usually 2.0 seconds for the static‑dissipative materials – to guarantee the rapid dissipation of any accidental static discharge during the handling of the ESD‑sensitive devices.
- Influence of the relative humidity, the temperature and the surface‑contamination on the electrical properties: the surface resistivity and the static‑decay time are measured after the conditioning at 12 % RH and 23 °C, and at 30 °C and 80 % RH, and after the application of the common cleaning‑agents and the soldering‑flux residues, ensuring that the board maintains its anti‑static function across the full range of the manufacturing‑floor and the field‑service environments.
- Long‑term stability and the humidity‑ageing of the anti‑static performance: the board is stored at the elevated temperature and the humidity for a defined period, and the surface resistivity is remeasured at the intervals, quantifying the rate of the anti‑static‑additive depletion and the shelf‑life of the ESD‑protective material.
Mechanical Strength and Structural Integrity – Anti‑static Glass Fiber Board Testing According to ASTM D790, ISO 178 and ASTM D256

- Charpy and the Izod impact resistance according to ISO 179‑1 (Plastics – Determination of Charpy impact properties) and ASTM D256 (Standard Test Methods for Determining the Izod Pendulum Impact Resistance of Plastics): the notched and the un‑notched specimens are struck by a calibrated pendulum, and the energy absorbed during the fracture is reported, quantifying the toughness of the glass‑fibre board and its ability to survive the accidental impacts during the assembly, the maintenance and the service.
- Measurement of the board thickness, the flatness and the dimensional stability under the thermal and the humidity exposure according to the internal procedures: the thickness is measured by a calibrated micrometre, the flatness is checked on a surface‑plate, and the change in the dimensions after the exposure to the elevated temperature and the humidity is reported, ensuring the correct fit‑up of the panels and the long‑term geometric stability of the ESD‑safe installation.
Thermal, Fire and Environmental Durability – Anti‑static Glass Fiber Board Testing According to ASTM D648, UL 94 and ISO 175
- Determination of the heat‑deflection temperature and the Vicat softening point according to ASTM D648 (Standard Test Method for Deflection Temperature of Plastics Under Flexural Load) and ISO 75‑2: the temperature at which the board deflects by a specified amount under a defined flexural load is measured, defining the maximum service temperature for the anti‑static worksurface that may be exposed to the hot soldering‑irons, the rework‑stations and the elevated‑ambient industrial environments. This anti‑static glass fiber board testing service verifies that the board will not soften, warp or sag under the expected thermal load.
- Vertical‑burn and the horizontal‑burn testing according to UL 94 (Standard for Tests for Flammability of Plastic Materials for Parts in Devices and Appliances) and the IEC 60695‑11‑10: the glass‑fibre board is subjected to a defined gas‑flame, and the after‑flame time, the after‑glow time and the dripping‑ignition of the cotton indicator are recorded, providing the V‑0, the V‑1 or the HB flammability rating that is required for the electrical‑enclosure, the cleanroom‑panel and the mass‑transit‑interior applications.
- Resistance to the chemical agents – the soldering‑flux, the alcohol‑based cleaners, the acids, the alkalis and the industrial solvents – according to ISO 175 (Plastics – Methods of test for the determination of the effects of immersion in liquid chemicals) and ASTM D543: the board is exposed to the representative chemicals that are encountered in the electronics‑manufacturing, the laboratory and the industrial environments, and the change in the mass, the resistivity, the flexural strength and the appearance is reported, certifying the long‑term chemical compatibility of the ESD‑safe surface.
- Resistance to the ultraviolet radiation and the accelerated weathering according to ASTM G154 (Standard Practice for Operating Fluorescent Ultraviolet Lamp Apparatus for Exposure of Non‑Metallic Materials) and ISO 4892‑2: the board is exposed to a cycle of the UV‑A or the UV‑B radiation, the heat and the condensation, and the colour‑change, the surface‑cracking and the retained flexural strength are evaluated, predicting the outdoor‑storage and the exposed‑service life of the glass‑fibre board.
- Resistance to the mould and the fungal growth according to ASTM G21 (Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi) and the ISO 846: the board is inoculated with the spores of the Aspergillus niger, the Penicillium funiculosum and the other common fungi, and the extent of the mould‑coverage and the loss of the mechanical strength are evaluated, providing the data that the specifier uses to approve the board for the humid, the condensation‑prone and the tropical environments.
