Candles and votives testing

Fitness-for-purpose assessment of glass containers intended for use as candle holders, or ‘votives’, in order to demonstrate proper due diligence when placing products upon the market.

This suite of tests is conducted in accordance with the American Standard ASTM-F2179. The featured tests comprise assessment of residual stress using the annealing method outlined in ASTM C148 (for transparent containers) or in accordance with the industry standard scratch-test (for opaque containers) and thermal shock resistance in accordance with ASTM C149.

Further complimentary tests, such as glass thickness and distribution and design and visual assessment, are recommended in order to give a fuller picture of product performance once in market.
