Is Pacific quartz safe? Yes: safe to prepare food on, safe for the air in your home, and made to tested, certified standards. Every quartz brand says its countertops are safe, so this guide shows the proof behind ours.

Certifications are how you check a safety claim. They are issued by independent bodies that test the product or audit the factory against a published standard, so they mean the same thing whichever quartz company you buy from. Pacific quartz holds four of the certifications buyers ask about most, NSF/ANSI 51, Greenguard Gold, CE marking and ISO 9001, and our low silica range is tested by SGS. Here is what each one means for you, and how to check it.

Safe for food: NSF/ANSI 51

NSF/ANSI 51 is a standard for materials used in food equipment, set by NSF International, an independent public health organisation. To be certified, a surface has to show that it doesn't release harmful substances into food and that it can be cleaned properly.

For quartz kitchen countertops, this is the certification that answers the most common question: is a quartz countertop safe to prepare food on? A surface certified to NSF/ANSI 51 is safe for direct food contact, so you can knead dough, roll rotis or rest cut fruit straight on the counter.

Pacific quartz is certified to NSF/ANSI 51, so it is safe for direct food contact in a home quartz kitchen and in commercial kitchens, restaurants and cafés, where food safety rules apply.

Safe for the air you breathe: Greenguard Gold

Greenguard certification is run by UL, the safety science company. It tests how much a product releases into indoor air as volatile organic compounds (VOCs), the chemicals that can give off a smell from new furniture, paint or surfaces.

There are two levels. Greenguard sets limits for ordinary indoor spaces. Greenguard Gold sets stricter limits, based on what is safe for sensitive groups such as children and older people, and it is the level asked for in schools and healthcare buildings.

A large slab of quartz engineered stone countertops covers a lot of surface in a kitchen or bathroom, so low emissions matter. Pacific quartz holds Greenguard Gold certification, the stricter level, so it is suitable for homes with children and for schools and hospitals.

Made to European safety rules: CE marking

CE marking shows that a product meets the European Union's rules for safety, health and environmental protection. For quartz and other agglomerated stone, it falls under the EU's rules for construction products. The manufacturer tests the product against the relevant harmonised European standard and issues a Declaration of Performance that lists its key properties.

CE is a declaration of conformity rather than a quality award, but it is a legal requirement for selling building products in the EU, and the Declaration of Performance gives buyers real numbers to compare. For homeowners in India, it means the same Pacific slab sold here meets the safety and performance rules of the European market. For quartz slab suppliers and importers in Europe, it is essential. Pacific exports to more than 45 countries and runs a European warehouse in Poland, and our quartz carries CE marking.

Safe, slab after slab: ISO 9001:2015

ISO 9001 is the international standard for quality management, published by the International Organization for Standardization. It certifies the company's processes rather than one product: how it controls raw materials, production, testing, complaints and improvement. An accredited certification body audits the factory before issuing the certificate and checks it again regularly.

For a buyer, ISO 9001 is about consistency. It means the slab you see as a sample and the one delivered to your home come out of the same controlled process. Pacific holds ISO 9001:2015 certification for quality management, so the safety standards behind one slab apply to every slab we make.

The test results behind the safety claims

Certificates tell you a product passed a standard. Test results tell you by how much. Pacific quartz is tested to European and American standards:

Water absorption below 0.03% (EN 14617-1), which is why the surface is non-porous and stain resistant.
Stain resistance rated "not affected" (ASTM C1378).
Mohs hardness of 6.5 to 7.5, which is why quartz stone resists scratches.
Flexural strength of 31 to 75 N/mm² (EN 14617-2).
A pass on the ASTM Z124 test for wear and cleanability.

For the people who cut and fit the slabs, silica content matters too. The crystalline silica content of Pacific's Ecosurfaces, our low silica quartz range, is tested by SGS, the independent testing company. Our guide to low silica quartz explains why.

Safe in your home, safer to make

Put together, here is what the certifications and tests mean for you. A finished Pacific quartz counter is safe to cook on, eat from and live with every day. It gives off no dust in normal use, keeps indoor emissions low, and its non-porous surface is easy to keep hygienic.

We also think safety should reach the people who make and fit the slab. That is why we developed Ecosurfaces, with zero-silica and low-silica options and silica content tested by SGS, so cutting and polishing on site is far safer for fabricators and installers.

We don't call any stone product "100% safe", because cutting any engineered or natural stone still needs proper dust control. What we can show you is the evidence: named certifications, published test results and independent testing.

How to check a certificate is real

A logo on a brochure is not proof. When you compare quartz countertop manufacturers, a few checks take only minutes:

Ask for the certificate itself, not just the logo, and check the company name matches the brand you are buying.
Look the company up in the certifier's own online listing. NSF and UL both publish searchable databases of certified products.
Check the scope. A certificate may cover one product range or one factory, not everything the brand sells.
Check the date. Most certifications are renewed or re-audited regularly, so an old certificate may have lapsed.
For CE marking, ask for the Declaration of Performance. For ISO 9001, check the certificate number with the certification body that issued it.

A trustworthy quartz company will share all of this without hesitation.
