The Quality inspection process:

Quality Assurance testing of Latex exam gloves can be divided into the following steps:

  • Random Sampling of gloves as per the Mils standard.
  • Water-tight testing for pinholes as per AQL requirement.
  • Visual defect testing for Major and Minor defects.
  • Physical dimension and tensile strength testing.
  • Glove count per box.

1. Random Sampling

Gloves are randomly sampled from finished goods lots/batches as per the Mil’s standard after which they are taken for visual and water-tight testing. Production lots of 100-200 cartons per lot is sampled for glove inspection and a glove defect report is compiled. The process is repeated for all the production lots of the full order. Once small lots are sampled, a final sampling of a big lot of a full order is done to complete the inspection. The final glove report is sent to Management for approval of shipment.

 

2. Visual and Water-tight testing

The randomly selected gloves undergo stringent water-tight and visual testing. In this test, the gloves are tested for pinhole leakage, major and minor defects. Only batches that comply to the acceptable level for defects are approved for shipment to you. This test is done to ensure your hands are safe from cross contamination of any kind.

To note: 1000 ml of water is poured into sampled gloves and kept for 2 mins until any leak is detected as per the EN 455-2:2015  standard.

3. Physical dimensions and tensile strength testing

The glove lots that have passed the criteria for holes now undergo the physical strength and dimension testing. The gloves must comply to a minimum Force at break (N), elongation,dimension and thickness parameters to be given the green signal for shipping to you. All these tests are done to ensure that the glove fits comfortably in your hands without tearing and is easy to use.

Lab test equiments are calibrated once a year for assurance of correct results. You can be assured of correct inhouse reports.

4. Glove count

Last but not the least, the glove quantity must comply to:

  • 100 pcs in a dispenser box and 10 dispenser boxes in a carton.
  • 100 pcs in a polybag and 40 polybags in a woven sac depending on the requirement of the customer.

Glove count testing of packed gloves is done to ensure you are getting complete gloves as promised.
