Incorporated in 1959, originally serving the local textile companies in West Yorkshire.

We have considerable experience in fibre composition analysis of all forms of textiles, this expertise has been developed from analysis of many forms of textile waste over a number of years, some of the samples tested often contained 10 different fibres. Some of the techniques for fibre identification have been developed by ourselves, due to the introduction and more widespread use of new specialist high performance fibres, which are not covered by the relevant British and European Standards.

Increasing demand for performance testing of yarns and fabrics has resulted in our investing in new equipment to carry out a range of physical and colour fastness tests. The introduction of The Furniture & Furnishings (Fire) (Safety) Regulations 1988 has resulted in ASL developing the necessary expertise and experience in this field and offering a fast, reliable service for the relevant fire safety tests.

We also cover a variety of tests on raw wool including scoured yield, moisture regain, extactable matter, fibre diameter determinations by projection microscope or airflow techniques and the taking of core samples from wool bales for subsequent analysis.

As members of the BSI we receive monthly updates of all changes to British, BS EN and BS EN ISO Standards, and maintain our Standards accordingly, we offer a fast and reliable testing service at a reasonable cost.

Expert witness statement reports for legal cases involving driving whilst over the prescribed limit for alcohol can be provided by B. Rodney Smith. The calculations for these are performed using a computer program developed in house by Philip. J. Addinell to give accurate and quick calculated breath/blood alcohol levels using either the Widmark or Total Body Water equations.

The results for Fibre Compostion and Wool Fibre diameter together with the associated fibre diagram are calculated and printed using our own specially developed software to give accurate and quick results from the analysis figures, most of the other test results involving calculations are also processed by modules from the same program.
