Test method development and protocol

Test methods form the basis of performance specifications, allowing repeatable, controllable and meaningful assessment of the physical performance of a packed product. Whether it be routine validation testing or one-off technical investigation, using the correct test method is key to both running a successful assessment and to delivering the right conclusions for decision making.

Pira regularly undertakes testing in acccordance with internationally recognised distribution test methods including ASTM D4169, ISTA, ISO, EN, BS standards.

Bespoke test method development

For many clients and products, validation and troubleshooting requires a highly tailored laboratory assessment method which takes account of product, pack and supply chain specifics. Pira has been developing bespoke test methods for global brand owners for more than 40 years.

Commonly the bespoke method development process includes:

  • Site visits throughout the chain (point of manufacture, packing lines, palletisation, warehousing, handling, distribution centres, retailer DCs back of store, front of store, point of sale)
  • Hazard observation and identification
  • Remote field data acquisition
  • Supply chain process mapping
  • Rationalisation of process to produce core test method

Retail supply chain test method development - mixed loads (roll cages)

Prior to 2005 Pira undertook a multitude of test development projects on a single-client basis. During 2005 Pira set up and undertook a ground breaking test method development project specifically for the multiple retail grocery supply chain for a multi-client consortium (of leading brand owners and packaging suppliers).

A key feature of this project was to investigate and document the loading conditions of mixed arrangements of goods (roll cages, mixed pallets) not addressed in any previous supply test methods. This part of grocery distribution was shown to be the single most critical part of the supply chain in terms of damage in Pira's 2004 Strategic Futures member project entitled 'Damage in the Supply Chain'.
