Personal Protective Equipment’s (PPE)

To ensure and meet your needs we provide rigorous evaluation and expansive testing capabilities to deliver assurance that, even under the most stressful or hazardous conditions, your products will provide sustained protection. Types of PPE testing includes Face shield testing, Alcohol/isopropyl Testing, Disinfectant testing, Medicinal gown testing, Gloves testing etc

Face Shield Testing

Face shields are personal protective equipment devices that are used by many people for protection of the facial area and associated mucous membranes (eyes, nose, mouth) from splashes, sprays, Bacterial spray and spatter of body fluids. Face shields are generally not used alone, but in conjunction with other protective equipment and are therefore classified as adjunctive personal protective equipment. Generally, a face shield is situated at the crown of the head and is constructed with plastic to cover the user’s eyes and face. Face Shields Intended for a Medical Purpose must not contain any materials that will cause flammability, or the product meets Class I or Class II flammability requirement per 16 CFR 1610

The main tests for face shield are follows.

  • Penetration of Synthetic Blood Testing (ASTM F1862)
  • Flammability Testing (16 CFR 1610)
  • Quality of material and surface (EN 167:2001)
  • Robustness (EN 168: 2001)
  • Resistance to Ageing (EN 168;2001)
  • Resistance to Ultraviolet radiation (EN 168;2001)
  • Resistance to corrosion (EN 168;2001)
  • Resistance to Ignition (EN 168;2001)
  • Protection against high speed particles (EN 168;2001)
  • Protection against droplet or splashed of liquid (EN 168;2001)
  • Protection against molten metals or hot solids (EN 168;2001)
  • Protection against large dust particles (EN 168;2001)
    • EN ISO 13688 Protective clothing — General requirements
    • EN 14126-B Protective clothing – Performance requirements and tests methods for
    • protective clothing against infective agents
    • EN 13034 PROTECTION AGAINST LIQUID CHEMICALS or Protective clothing against
    • liquid chemicals – performance requirements for clothing with liquid-tight (Type 3) or
    • spray-tight (Type 4) connections, including items providing protection to parts of the
    • body only (Types PB [3] and PB [4])
    • EN 343 for water and breathability or equivalent

Alcohol/Isopropyl Testing

ISOPROPYL ALCOHOL (IPA) is widely accepted as a good liquid for keeping cleanroom surfaces in pristine condition. At room temperature, methyl alcohol has three times the vapor pressure than that of IPA. This means methyl alcohol will evaporate at a much more rapid pace, making it difficult to keep wipers damp enough to efficiently remove surface particles. In addition, the higher vapor pressure of methyl alcohol means more of the alcohol will be in the vapor state, which means increased exposure to stringent alcohol fumes for cleanroom operators.

The main test done with Alcohol and IPA is as follows.

Purity DIN 55685

Water ASTM D1364

Appearance Clear & Free from Suspended Matter ASTM D4176

Colour ASTM D1209

Initial diluted odour SMS 547

Non-Volatile Matter ASTM D1353

Distillation ASTM D1078

Water Miscibility ASTM D1722

Disinfectant Testing

Disinfectant tests have the same final purpose, namely measuring the antimicrobial activity of a chemical substance or preparation, a large number of testing methods has been described. They are subdivided into suspension tests, carrier and surface disinfection tests and other practice-mimicking tests. The suspension tests comprise qualitative and quantitative suspension tests, and, as derived tests, the determination of the phenol coefficient and capacity tests. There is an essential difference between a carrier test and a surface disinfectant test: in the former case the carrier is submerged in the disinfectant solution during the whole exposure time, whereas in the latter case the disinfectant is applied on the carrier for the application time and thereafter the carrier is drying during the exposure. following are the tests.
