ALLERGY STANDARDS - CERTIFYING PRODUCTS FOR HEALTHIER INTERIORS AN OVERVIEW OF THE asthma & allergy friendly™ CERTIFICATION FOR SPECIFIERS How do product claims such as the asthma & allergy friendly ® Certification Programs encourage innovation in the building industry? It is estimated that we spend up to 90% of our time indoors. The asthma & allergy friendly ® Certification Program is built around the concept of a “whole of building” approach to indoor air quality. Every product or building material brought into your environment can introduce Volatile Organic Compounds (VOCs) or allergens. The Certification Program challenges Industry to innovate and develop products that contribute to a healthier indoor environment. Over 60% of asthma and allergy sufferers find it difficult to choose appropriate products for their homes and work spaces. Our Certification Mark helps specifiers to make informed buying decisions on behalf for their customers, not only for those with sensitive airways, but for anyone concerned about their indoor environment. How does the   asthma & allergy friendly ®  Certification Program compare against other product claims in the building products industry such as the GreenGuard Gold and FloorScore? The asthma & allergy friendly ® Certification Program has a chemical and VOC aspect to the testing similar to other programs, however the program is mainly concerned with air-borne allergens and irritants that may aggravate sensitive individuals. As such we move beyond other industry certifications and assess the “in-use” phase of a products life-cycle. For example, our flooring standard examines how well allergens can be cleaned from the flooring. If the flooring traps allergens, then you may have a build up and get exposed to allergens even when cleaning the floor regularly. Our insulation standard tests the amount of fibre that is shed during the installation to ensure that a high amount of fibre isn’t collected in the building during this phase. We also carry out longer terms studies to determine the ability of the insulation to support mold growth. Can you talk us through the testing process; using flooring for example. After submitting your product for testing, we will review the details of the product range and send it to one of our approved testing partners situated world-wide. Testing can take 8-10 weeks to complete and usually includes chemical, biological and physical assessment. Using the flooring standard as an example, it is broken into two main parts, the chemical and the allergen testing. The chemical testing is carried out in a small environmentally controlled chamber that collects the VOCs emitted from the product. The flooring is installed in a test chamber using any adhesives that are supplied or recommended by the manufacturer. There is no conditioning period and samples are collected at 1-day, 2-days and 14-days after installation. The levels of VOCs measured must be within Dr Joey DeCourcey, the certification limits to pass. We Allergy Standards’ Senior assess these time points as often Scientific Officer people move into their houses immediately after installation of flooring, and VOC can emit from a floor for an extended period of time. High-quality flooring should be within the recommended exposure limits for specific VOCs that can trigger symptoms in sensitive individuals. The second part of the testing assesses the potential for the flooring to trap allergens and dust. The Flooring is installed in a large environmental chamber and test dust is introduced into the chamber and allowed to settle. The flooring is cleaned according to the manufacturer’s instructions and the air is sampled during the cleaning. After cleaning, the floor is tested to ensure that allergens are effectively removed from the surface. Flooring that can be cleaned well and does not trap dust and allergens reduces the risk of exposure. Once a product has met the strict criteria set out in the standard it is then eligible to join the certification program. How important is Research and Development to a company seeking Certification and how do your scientists help them achieve the  asthma & allergy friendly ®   Certification? We challenge companies to innovate and create products that contribute to a healthier indoor environment. This often requires significant R&D efforts by the manufacturer. ASL offers services to partner with manufacturers in the R&D phase to ensure that products are suitable for those with sensitive airways. This is becoming increasingly important as it is estimated that by 2025 more than 50% of all Europeans will suffer from allergies. We partner with companies to provide landscape analysis, consultancy on performance testing or formulations, and collaborate to effectively market the health-based attributes of their product and the certification program. We draw on our experience not just in building materials, but also other industries such as consumer electronics and textiles to help consumers to create the best indoor air environment with the goal of avoiding any unnecessary allergy triggers in the home.
