The company said it is on track to deliver 2018 targets of good organic revenue growth at constant rates, along with moderate margin expansion.

Intertek, along with its peers like Switzerland's SGS and France's Bureau Veritas, are benefiting from expanding regulations, notably for food safety and e-commerce, and have recently seen their minerals business recover.

Alongside carrying out safety tests on trains, toys and a range of other products, the FTSE 100 company also tests oil and equipment.

The company said its resources-related businesses saw stable trading performance in the period and reported an organic revenue growth of 0.3 percent on robust growth in demand for testing activities in its minerals business.

Revenue from Jan. 1 to April 30 fell 2.5 to 861.2 million pounds at actual rates, the company said.

Intertek, which acquired Malta-based Aldo Abela Surveys and Colombia's Proasem SAS this year, said its products-related businesses delivered a 6.6 percent organic revenue growth at constant rates.
