How to conduct product testing for safety, durability, and compliance

To sell products legally in the UK, you must ensure they are safe for consumers and meet specific British safety regulations. This involves identifying the legal standards for your category, performing rigorous durability tests, and often hiring an accredited third-party laboratory to certify that your product won't cause harm or fail under pressure.

1. Identify the Legal Standards

Before you test, you need to know what you are testing for. In the UK, the "General Product Safety Regulations 2005" require all products to be safe. However, certain items have much stricter, specific rules. You should check if your product falls into these categories:

• Toys: Requires strict chemical and physical testing (choke hazards, flammability).
• Electricals: Must meet electromagnetic compatibility and low voltage safety rules.
• Cosmetics: Requires a Safety Assessment by a qualified chemist.
• Food Contact Materials: Anything that touches food (like a bamboo plate) must not leach chemicals.

Most products intended for the UK market now require the UKCA (UK Conformity Assessed) marking. This replaces the old CE marking (though CE is still relevant if you plan to sell in Northern Ireland or the EU).

2. Set Your Quality Benchmarks

Compliance is the legal minimum, but durability is what builds your brand. Create a list of "real-world" tests your product should pass. For example:

• The Drop Test: Does it shatter if dropped from table height onto a hard floor?
• The Stress Test: If it's a chair, can it hold 150kg? If it's a bag, do the straps hold after 500 tugs?
• The Cycle Test: If it has a moving part, how many times can it be used before it breaks?

3. Decide: Self-Testing vs. Lab Testing

For low-risk items (like simple home decor), you may be able to "self-declare" compliance by performing your own documented tests. However, for high-risk items or to gain professional credibility, you should use a UKAS-accredited laboratory.

Pro Tip: When searching for a lab, look for "UKAS accreditation." This is the gold standard in the UK and ensures the lab's results will be accepted by insurance companies and retailers.

4. Create a Technical File

Testing is useless if you don't keep records. You are legally required to maintain a "Technical File" for every product you sell. This should include:

1. Detailed descriptions and photos of the product.
2. A list of the safety standards applied.
3. Reports from any lab tests or internal tests.
4. A "Declaration of Conformity" (a document signed by you stating the product meets the law).
5. Copies of the instructions and safety warnings provided to the customer.

5. Ongoing Batch Testing

Product testing isn't a one-time event. Even after your prototype passes, you should occasionally test samples from your production line. This ensures that the quality hasn't "drifted" because of a change in raw materials or a mistake at the factory.

Product Type	Common Test Required	Key Regulation
Soft Toys	Small parts/Flammability	Toy Safety Regulations
Kitchenware	Chemical Migration	Food Contact Materials Regs
Electronics	Insulation/Earthing	Electrical Equipment (Safety)
Clothing	Drawstring safety/Azo dyes	GPSR / REACH

Final Advice

Do not skip this step to save money. If a product is found to be unsafe, Trading Standards can order a mandatory recall, fine your business, or even pursue criminal charges. Proper testing is the best insurance policy your business can have.
